From increased recognition of property rights to adjustable walls and windows to biospheres, electronic implants in construction, behavior-centered products and force fields–it's all on the way. The expanding role of the front line–law enforcement.Slide10: Now Cain said to his brother Abel, “Let us both go away out to the field,” and while they were in the field, Cain attacked his brother Abel and killed him.” Genesis 4 verse 8Definition : Definition Crime is defined as “an act or commission of an act that is forbidden or the omission of a duty that is commanded by a public law and that makes the offender liable to be punished by that law.” Crime Figures for the United States: Crime Figures for the United States The UCR for 1995 reported nationally nearly 12 million serious crimes including murder, rape, robbery, aggravated assault, burglary, larceny, theft and motor vehicle theft. Not counted are a wide range of “minor” crimes, however the proportional data on the “major” crimes reported breaks down as 89 percent crimes against property and 11 percent crimes against persons.Reported Crime: Reported Crime Many of our decisions about what to do about crime are based upon reported crime, which do not include security incidents which may or may not be reported to the police. The national closure rate (solve rate) for all reported crime is approximately 21 percent.Unreported Crime: Unreported Crime National Crime Surveys, which are incorporated into census Bureau data, reveal that nationwide victimizations are reported to law enforcement approximately 35 percent of the time. A large number of unreported crimes, according to survey data, fall into the category of property crime and are considered minor by the victim. When unreported crimes are factored into the national closure rate, the law enforcement success rate falls to percent.Unacknowledged Crime: Unacknowledged Crime This is a large category of crime that is committed against corporations and organizations. Since it is not acknowledged, it obviously goes unreported. These crimes are measured, albeit poorly, by inventory shrinkage data maintained in accounting and inventory control systems. Inventory losses can be enormous. The commonly accepted shrinkage rate in retail corporations is 10 percent. Employee theft and shoplifting dominate this category. The ratio of employee theft to shoplifter theft is generally accounted as 5:1 to 7:1 depending on the product line. Reported and unreported crime losses were estimated to total $37 billion. It has been estimated that unacknowledged crime costs consumers in the United States an additional $100 to $200 billion.Undetected Crime: Undetected Crime Undetected crimes are losses which are yet to be discovered. Theft of time, illegal loans, illegally obtained insurance policies, fraud committed upon governmental agencies including Medicare/ Medicaid, false medical insurance claims and overpayment, welfare fraud and defrauding state and federal taxing bureaus. The cost of these losses has been estimated at to be $650 billion annually or 15 percent of the Gross National Product (GNP). The real long lasting tragedy is not the monetary loss but the societal loss of confidence in government and business and the elevated cost of some consumer products beyond the ability of a segment of the population to pay for it. Examples include, health insurance, auto insurance, the diminished ability to provide adequate health care, inability to provide livable mid and low-income housing etc.Slide17: The inherent fear women possess of the potentially aggressive behavior of the male half of the population against the weaker sex. The natural human fear of our own mortality and especially facing death in a sudden and violent incident. A universally held multi-cultural belief that causing the wrongful death of another is the ultimate crime for which the ultimate criminal penalty can by levied. FearWhat we know about Offenders can hold the Key: What we know about Offenders can hold the Key Whether the crime solution of the day is based on legal, social, psychological, biological or political theory, the fact remains that law enforcement must deal with the immediate results of crime regardless of what motivated the offender to commit the act itself. Criminal Justice and the Perceived Role of Law Enforcement: Criminal Justice and the Perceived Role of Law Enforcement “Catching bad guys” is the most visible and popular role for law enforcement/security. McGruff the Crime Dog is a symbolic reference to the traditional watchdog that catches crooks by the seat of the pants and Dudley Do Right, the cartoon Canadian Mountie always “gets his man”. Catching bad guys is the popular image of police and perhaps the image we, as law enforcement officers, want to perpetuate, however if we are honest with ourselves and reread the section on reported crimewe can realize that catching bad guys is the one thing that we fail to do most of the time.Criminal Justice and the Perceived Role of Law Enforcement: Criminal Justice and the Perceived Role of Law Enforcement The National Crime Prevention Institute defines crime prevention as “the anticipation, recognition and appraisal of a crime risk and the initiation of some action to remove or reduce it.” Criminal Justice and the Perceived Role of Law Enforcement: Criminal Justice and the Perceived Role of Law Enforcement “If it ain’t about arresting somebody - it’s gotta be crime prevention.”Criminal Justice and the Perceived Role of Law Enforcement: Criminal Justice and the Perceived Role of Law Enforcement The goal of this course is to systematically present crime prevention options in such a way that it enables the law enforcement problem solver to analyze and implement a blend of site specific solutions based upon proven, factually based principles. Read on and finally get “empowerment”... for real!Opportunity vs. Specific Target Crime–The Key: Opportunity vs. Specific Target Crime–The Key Somewhere in the problem solving process, we must look beyond the criminal events that make up the reported crime/calls for service quantification of area police effectiveness, and explore the motivation of the offender. Opportunity vs. Specific Target Crime–The Key: Opportunity vs. Specific Target Crime–The Key “Which Crimes can we truly prevent and which crimes are we simply displacing to another area, zone or city?”Example:: Example: A CPO routinely checking for repeat calls for service discovers a low-income motel along the main business corridor of his/her assigned area. This motel business is generating many calls for service linked to prostitution and drug sales and related issues and crimes. Residents in the neighborhoods immediately adjacent to the motel complain loudly and often of finding prostitutes servicing their customers in the alleys and residential driveways and business parking lots as well as people believed to be drug dealers frequenting the corners of street intersections directing their customers to the motel parking lot to complete the drug sale transaction. Evidence of narcotics use as well as used condoms from the prostitutes sexual activity litter the adjacent residential area and comprise a genuine health risk for the residents and especially the children in the area. Children are also at risk when numerous cars, not from the neighborhood, speed along their streets at all hours playing loud music and strangers openly shout vulgar language.Media Attention and the CPO’s Impact on that Resource: Media Attention and the CPO’s Impact on that Resource “Thou shalt never, ever speaketh to someone who holdeth a microphone or notepad or camera, lest one desirest one’s head to be handeth to him/her on a platter by the Chief (eth).”What is an Opportunity...Exactly?: What is an Opportunity...Exactly? Desire...ability...opportunity!” Slide28: “I wish I could run into one of those Nasty’s now; now that I’m a crime fighter!”Example One: Example OneExample Two: Example Two A basic and necessary tool this tradesman burglar has developed is a keen sense of observation and the ability to quickly and unobtrusively analyze a large number of ever changing variables within his environment as he looks for his next opportunity.Example Two: Example Two Approximately four minutes later, he is loaded up and back in his car and on the way to his local “fence” where he immediately disposes of the stolen goods, gets his money, satisfies his needs and plans for another day.Example Two: Example Two No newspaper articles, no film at eleven, no book deal or movie contract. In fact, the people who live in the neighborhood never even know about that home burglary until an alarm salesperson knocks on their door and tells them there was a house “robbed” in the neighborhood and the rest of the neighbors are all buying his $1500 alarm package which coincidentally is on sale this week only for $999.Opportunity: OpportunityQuestion: Question Is this an example of bug prevention or bug displacement? Has the overall statistical incidence of bugs in that neighborhood gone down, increased or stayed about the same? Did the bugs that ran out from under the rock stop being bugs and stop doing bug like things when they were forced out of their home?Opportunistic Crime: Opportunistic Crime What we can and do control very well and the reader will become especially adept at, as this study progresses, is displacing the opportunistic criminal out of selected areas.Specific Target Crimes: Specific Target Crimes Kidnapping for ransom Workplace Violence Contractual murder High profile well planned theft (i.e. Fort Knox, Hope Diamond, Great Train Robbery) Treason Serial Killing (Specific Victim Profile; prostitute, student, waitress) Industrial Espionage Theft of High profile Intellectual Property and Computer Crime.Squaring with the Problem: Community Policing: “Intelligence is not knowing everythingno one can. Intelligent people just know where to go to get their answers.” Henry Ford Squaring with the Problem: Community Policing It is time to organize our toolbox and come into a rational understanding of what we can do to control opportunistic criminal behavior. Read on as we systematically organize your toolbox and simply explain the options available to control opportunistic behavior.Controlling Opportunistic Crime: Controlling Opportunistic CrimeOrganized Controls: Organized Controls IMPORTANT: None of these options “stand alone” as the sole method of control.Goal of Organized Control: Goal of Organized Control Organized controls are characterized by people intensive methods of controlling opportunistic crime. The goal of organized controls is to displace the opportunistic potential offender by capitalizing upon his/her natural fear of being detected and or apprehended during the commission of an opportunistic crime. High Visibility Patrol : High Visibility Patrol Law enforcement officers are often tasked with the assignment to be visible. Whether the visibility is in a crowded daytime event with thousands of people or a dark and solitary neighborhood during the midnight shift, the presence of an uniformed symbol of control is desired. Uniformed high visibility patrols can include: Professional Law Enforcement Officer (on duty patrol) Professional Law Enforcement Officer (working off duty paid by site) Proprietary Security Force (owned by site) Contractual Security Force (hired by site) Courtesy Patrol (uniformed resident of apartment/ condominium site) High Visibility Patrol: High Visibility Patrol In addition to loss control, the effectiveness of the security force in the corporate environment and the amount of attention and support it receives from management is often influenced by employee feed back loops usually called employee safety committees who can provide input into implementation and effectiveness of the security personnel.Volunteer High Visibility Efforts: Volunteer High Visibility Efforts Neighborhood WatchTenant Unions/Condominium Associations and Watch Groups: Tenant Unions/Condominium Associations and Watch Groups The law enforcement officer should actively seek to maintain his/her position as impartial seeker of the truth and remembering the goal of establishing some type of organized control to displace opportunistic criminal behavior.Tenant Unions/Condominium Associations and Watch Groups: Tenant Unions/Condominium Associations and Watch Groups Apartment/Condo Watch Organized Controls; Written Policies/Procedures, Rules and Codes Reinforcing Organized Controls; Signage Deed Restricted Communities Frailties of Organized Controls and Human NatureMechanical Controls: Mechanical Controls The professional law enforcement/problem solver, when formulating a site specific, blended crime prevention plan formulated to displace the potential opportunistic offender must consider mechanical controls which comprise the second general crime prevention option. Mechanical Controls fall into the following general categories: Locks and locking devices and access control systems of all types. Alarm systems, both self-contained and monitored. Camera systems, both negative film and video. Fences and gates both interior and exterior. Lighting systems (see Natural Controls, next chapter).Mechanical Controls: Mechanical Controls Access Control and Security System Integration. This is a monthly publication from PRIMEDIA Intertec located in Atlanta, Georgia and is available by contacting (707) 955-2500. This publication also distributes an annual product buyer’s guide which lists mechanical controls by type and lists manufacturer and dealer information. American Society for Industrial Security (ASIS) Product Buyers Guide. This annual publication is distributed to all members of ASIS and is available by contacting (703) 522-5800.Definition and Goal of Mechanical Controls: Definition and Goal of Mechanical Controls Mechanical controls are defined as those devices put into place in an environment which are intended to define, promote and reinforce the physical security of that environment. Different types of mechanical controls can be layered into an environment to primarily secure the environment and secondarily displace the opportunistic offender away from that environment. See appendix on security devices and security assessment.Doors, Doorways and Locking Devices (Residential): Doors, Doorways and Locking Devices (Residential) The following items are common things to look for and common mistakes made by homeowners:Use of Spring Locks rather than Deadbolt: Use of Spring Locks rather than Deadbolt Exterior doors generally open outward which results in a gap or reveal where the door bolt enters the door frame. Spring locks are easily accessed and pushed back by placing a knife of similar device against the bolt and pushing it back into the door. Deadbolt locks are fixed into the locked position and therefore are not able to be pushed back. A door latch protector is a metal device which attaches to the door and covers the latch and prevents the bolt from being accessed from the exterior.Use of Single Cylinder Deadbolt Lock within 40 inches of Glass in door or door frame: Use of Single Cylinder Deadbolt Lock within 40 inches of Glass in door or door frame This is a common error even in new residential construction. The interior of the lock is equipped with a thumb latch which is easily opened by breaking the glass in the door or doorway, reaching inside and opening the lock.Improper Door Application: Improper Door Application This is observed most often in low income or rental property where a hollow core interior door is placed in an exterior door frame. The result is, the thin door veneer facing the exterior starts to peel away when exposed to the elements of rain and harsh sun light since the door was originally made for interior use only.Installing High Quality Locks in Low Quality Doors/Door frames: Installing High Quality Locks in Low Quality Doors/Door frames Generally speaking, when force is applied to a door, locks don’t fail–the door or door frame does. Before the law enforcement professional recommends upgrading locks, remember to examine the door and door frame.Exterior doors lack viewing device: Exterior doors lack viewing device Exterior residential doors should be equipped with some type of peep hole or door viewer which enables the occupant to view who is outside the door without opening the door and compromising security.Rear sliding glass doors not properly secured: Rear sliding glass doors not properly secured There are several simple methods available to properly secure sliding glass doors. These doors are especially vulnerable since they are hingeless and are generally able to be lifted out of the door frame. (See appendix)Doors and Doorways (Business): Doors and Doorways (Business) Compromised door security for Convenience Employees of corporations and small businesses will often devise methods to peg doors open by blocking complete closure, stuffing paper in the door latch box, or simply unlocking doors which are suppose to stay locked; all for the sake of employee convenience. It is not uncommon to walk behind small businesses in shopping centers and strip malls and find rear doors unlocked or standing open. Restaurants, bakeries and dry cleaners will often leave doors open for the sake of ventilation.Other Types of Access Control Methods: Other Types of Access Control Methods In addition to the traditional lock and key there are other types of access control systems available and in use primarily in the business environment. Keyless locks which uses a mechanical pin type key pad. The combination can be easily changed thereby eliminating re-keying. Magnetic Locks which are reprogram able and are most commonly seen in motel applications. These locks are stand alone or networked with a record keeping capability for logging employee number, door number and time of access. Other Types of Access Control Methods: Other Types of Access Control Methods Proximity Cards which are part of an automated and networked perimeter control system and have the capability of recording employee, door location and time of entry exit. These systems can also be integrated into a video system and may turn on video cameras when card is used. Hand Geometry, Retinal Scanner and other Biometric Controls. These systems which were considered “star wars” technology only a few years ago are now in use in some high profile corporate environments. These systems do not depend on cards which can be easily lost or stolen, but rather function on biological information specific to the employee only.Alarm Systems (Residential): Alarm Systems (Residential) The most important thing to remember regarding residential alarms is that they are simply comprised of components which are commonly used by all alarm companies:Common Alarm System Components: Common Alarm System Components Sounding Device which is some type of siren or loud electronic noise maker which is placed on both exterior and interior of the home and sounds when the alarm in activated. Motion Detector which is commonly infrared and ultrasonic which means the device will not activate without both motion and heat combined. This eliminates false activation’s due to plant motion or other ventilation related movement. Motion detectors can be modified with lenses called “pet alleys” which limit the detecting ability only above a certain height so that floor walking pets will not set off alarm. Vibration Sensor commonly called “glass break” detector which is usually installed in rooms with large windows to activate the alarm prior to motion detector being activated.Common Alarm System Components: Common Alarm System Components Control Panel which can be supplemented with remote panic alarms which are hand held and operate much like a remote garage door opener from both inside and outside the home. Battery Backup which notifies the alarm company when there is a loss of electrical power to the home or their is a discontinuance in the telephone circuit, as would occur if telephone lines to the residence were cut from outside the home.Camera Systems: Camera Systems Negative film camera installations are still fairly common in bank applications and, like any other camera installation, depend upon proper placement angle and camera height in order to be effective. The greatest advantage of the negative film camera is the high quality picture potential using a standard photograph negative versus the grainy appearance of an enlarged video reproduction, especially if a poor quality, old, or badly worn video tape is used. The quality of video reproductions is improving steadily as digital technology becomes more common place.Camera Systems: Camera Systems Video camera systems are component systems which are readily adaptable to many situations. As was stated above, the most important variables to be considered when recommending a video system are proper camera height, angle and an adequate light source for exterior applications. Modern video camera light gathering capabilities are better than they have ever been since the advent of the smaller chip camera, however these cameras will not work without some minimum amount of light being available.Camera Systems: Camera Systems Video camera installations are commonly networked with simple sequencer which individually activate the cameras in the system and allow viewing on monitors (television screens) which are also networked. Rather that using a sequencer which shows only one camera view at a time, there exists the option of using the monitor in a “quad plex” or greater, which simply uses the single monitor screen and segments the screen into many individual views of different cameras.Fence and Gate Methods of Control: Fence and Gate Methods of Control Some of the most common errors law enforcement professionals seem to make regarding the subject of fences are: Recommending a fence be stockade or other solid material which blocks the ability to see beyond it. Creating a private space also creates a criminal opportunity which an opportunistic offender can hide behind. (See Natural Controls; Surveillance) Recommending fence height above maximum allowable. Fence height, composition, etc. are regulated by city and county codes. Most cities require a permit to erect a fence which allows officials to insure fence is complying with code. Frustrated land owners often times express a desire to erect a very tall fence and are looking for agreement from the law enforcement professional. The officer can remind the landowner of the variance process if the proposed fence height exceeds maximum allowable height.Fence and Gate Methods of Control: Fence and Gate Methods of Control Recommending topping fence with barbed wire, razor wire, concertina wire etc. Frustrated landowners will often express a desire to place some type of formidable material on top of a fence. Again, the proper advice would probably be to consult city, county officials regarding the practicality and legality of such an application. Also, much like guard dogs being left at a business overnight, insurance companies are taking a hard look at urban installations of material designed for rural application. Automated gates and gated communities. Use of automated gates is on the increase, especially in apartment and condominium applications where concern about opportunistic crimes such as auto theft, auto burglary and to a lesser extent residential burglary, is a concern. Entry gates are often marketed by these communities as a security selling point for potential new residents.Natural Controls: Natural Controls Learning Objectives: Define the commonly misunderstood and mispronounced practice of Crime Prevention through Environmental Design. CPTED (pronounced “sep-ted”). Discuss the history of building and community design as it related to safety and the history and theories of the major players in 20th Century research, study and development of CPTED. Examine the necessity and benefits of examining all the data available in a community including crime analysis, community demographic information, land use and zoning maps, enterprise zones etc, Resident surveys and input, fear maps and design charettes. Examine the three basic principles of CPTED (natural access control, natural surveillance and territorial reinforcement) and maintenance. Zones of transition and types of space.Natural Controls: Natural Controls Learning Objectives: Define the “3-D” approach used in space assessment and how the use of this approach can be used as a diagnostic tool when examining trouble spots in a community. Discuss the importance of understanding traffic flow patterns, street designations and the effects of traffic on neighborhoods. Traffic calming; what it really is and how to do it. Examine outdoor lighting options and the effect of color and light on human behavior. Illustrate CPTED in other applications, (small business, schools, public housing parks.) Recognize the importance of developing CPTED assessment tools and Interdisciplinary Teams. The rubber meets the road: CPTED Assessment Tabletop Exercise.Definition of CPTED: Definition of CPTED The proper design and effective use of the built environment can lead to a reduction in the incidence and fear of crime and an improvement in the quality of lifeData Assessment: Data Assessment We have stressed throughout this manual that factual information must be at the base of the professional law enforcement/ problem solvers blended crime prevention plan. In order to properly assess the problem to be prevented, an environmental (natural) study needs to include input of the following sources of information: Crime Analysis Data–This data can be plotted on a map in order to determine the areas within the environment that are supporting certain types of offenses and crime patterns. Demographic Data–Data concerning the nature of the population available from city and county government as well as Census Bureau information.Data Assessment: Data Assessment Land Use Information–City and county planning departments, zoning boards, traffic engineers and city and county commissions maintain zone maps relative to land use which show residential, industrial, commercial, parks, schools and special use areas. These maps are vital when attempting to get a grasp on the physical setting, natural boundaries and the natural geographic characteristics of neighborhoods, which at times are not congruent with the enumerated boundaries.Data Assessment: Data Assessment Observations–It is very helpful to conduct either formal or informal visual reviews of the physical space in question in order to get a first hand knowledge of how the space is being used, when and by whom and where the problems may be. Observations may include pedestrian and vehicle counts, on and off street parking, maintenance of yards and fences, the degree of proprietary or challenging behaviors exhibited by the residents and users, the presence of either controlling or avoidance behaviors and other more subtle factors such as observing how many homes have their window shades drawn overlooking parks and schools.Data Assessment: Data Assessment Resident and User Interviews–These interviews include people’s perceptions of where within the environment they feel safe or endangered. This may or may not be consistent with the crime data maps which show the occurrence of offenses. Often times this type of data collection can be supplemented by “fear maps” on which residents rate their feelings as they assess their own neighborhood environment. As neighborhood plans become more involved, city planners and designers have the option of calling citizens together for as long as an entire weekend and cooperatively collecting their input into revising the design of their own neighborhood. These types of planning sessions are called design “charettes” (say “share et”) which is French for “little cart.”CPTED Actors: CPTED Actors Normal User–the desired user of space. Non-User–opportunity seeking potential offender Observer–persons temporarily within an environment for a legitimate reason. Goal of Crime Prevention through Environmental Design: Goal of Crime Prevention through Environmental Design The law enforcement professional/problem solver’s goal is study the target environment and propose changes in that environment which ultimately cause the normal or legitimate user of the environment to feel safe, secure, productive and “in control,” thereby exhibiting proprietary, challenging behaviors towards the non-user, opportunistic individual who is continually assessing the environment looking for an opportunity to commit an offense. The non-user will sense that the environmental cues of the target environment are non-productive as his seeks a venue to commit an opportunistic offense and will thus be displaced to another space located elsewhere.The overlapping CPTED principles and strategies available to accomplish the goal are:: The overlapping CPTED principles and strategies available to accomplish the goal are: Natural Surveillance–The placement of physical features, activities and people in such a way as to maximize visibility including lighting of public spaces and walkways at night. Purpose: Capitalize upon the fears of the non-user which are the fear of being observed, identified and apprehended. Simultaneously reinforce the feeling of safety and security of the user; the need to be observed and non-isolated.The overlapping CPTED principles and strategies available to accomplish the goal are:: The overlapping CPTED principles and strategies available to accomplish the goal are: Natural Access Control–The physical guiding of persons entering, exiting and occupying an environment by the judicial placement of entrances, exits, fencing, landscaping and lighting. Purpose: Legitimate users of space are reinforced when the purpose and designation of space is readily apparent and obvious and the movement of persons follows a natural and direct route. Non-users find greatly diminished opportunity when natural conflict and confusion have been designed out of the environment.The overlapping CPTED principles and strategies available to accomplish the goal are:: The overlapping CPTED principles and strategies available to accomplish the goal are: Territorial Reinforcement–The use of physical attributes within an environment to express ownership, such as pavement treatments, fences, signage, art and landscaping. Purpose: Users of space are reinforced by assignment of space and will care for their space and exhibit challenging or territorial behaviors when a non-user presence is detected within the user’s space. Maintenance–Allows for the continued use of a space for its intended purpose and serves as a continued expression of ownership. Purpose: To ensure the effectiveness of the natural controls explained above. Maintenance prevents the reduction of visibility resulting from landscaping overgrowth and obstructed or inoperative lighting.Space Assessment - The 3 “D” Approach:More Tools: Space Assessment - The 3 “D” Approach: More Tools When the professional law enforcement/problem solver is attempting to diagnose a problem or conflict within an environment it is imperative to consider the design and use of the subject space from the legitimate users perspective. The 3 D concept is based upon the following three functions (dimensions) of human space as follows: All human space has some designated purpose All human space has social, cultural, legal or physical definitions which prescribe the desired and acceptable behaviors within a certain space. All human space is designed to support and control the desired behaviors within that space.Designation: Designation What is the designated purpose for this space? What was this space’s originally intended use? How well does this space support its current use? How well does this space support its intended use? Is there conflict between intended and current use?Definition: Definition How is this space defined? Is it clear who owns this space? Where are the borders of this space? (Where does it start and end?) Are there social or cultural definitions that affect how this space is to be used? Are there legal or administrative rules clearly set out and reinforced in policy? Are those rules (organized controls) reinforced with signage? Is there some sort of conflict between the designated definition and purpose of the space?Design: Design How well does the physical design support the intended function of this space? How well does the physical design support the definition of the desired or accepted behaviors within this space? Does the physical design conflict with or impede the productive use of this space or the proper functioning of the intended human activity within this space? Is there confusion or conflict in the manner in which the physical design is intended to control the behavior within this space? Some of the Most Common CPTED Strategy Activities: More Tools! : Some of the Most Common CPTED Strategy Activities: More Tools! The following are some common examples of CPTED strategies “in action” and are meant to provide some illustrations for the law enforcement/problem solver in forming a mental picture of the integrated and overlapping application of CPTED strategies within a subject environment: Provide clear border definition of controlled space. Provide clearly marked zones of transition which indicate movement from: Public space to semi-public or semi-private space to Private spaceSome of the Most Common CPTED Strategy Activities: More Tools! : Some of the Most Common CPTED Strategy Activities: More Tools! Relocate gathering areas to locations of greatest natural surveillance and access control; or away from the view of would be offenders. Place safe activities into unsafe locations to bring along the natural surveillance of these safe activities thereby increasing the perception of safety for normal users and risk for non-users. Remember: People will assume considerable risk if there is an attraction and other people. Place unsafe activities in safe locations to overcome the negative potential of these activities with the natural surveillance and access control of the safe area.Some of the Most Common CPTED Strategy Activities: More Tools! : Some of the Most Common CPTED Strategy Activities: More Tools! Redesignate the use of space to provide natural barriers to conflicting activities. Redesign or revamp space to increase the perception or reality of natural surveillance in order to increase the perception of safety for the user and the fear of observation for the non-user. Overcome distance and isolation through better communication and design efficiencies such as pedestrian paths and properly placed emergency telephones.Outdoor Light Source Types: Outdoor Light Source Types Incandescent: Incandescent Incandescent light sources can include common filament lamps with which we are all familiar as well as fire, gas lamps, mantle lamps, torches, candles etc. Advantages: Low initial cost Instant oninstant restart Compact light source Simple maintenance High color rendering index value (CRI) No ballast Can be dimmedIncandescent: Incandescent Disadvantages: Low Efficiency (Cost v. amount of light) Short Life (2000-3000 hours) Most expensive to own Florescent: Florescent Advantages Low initial cost Nearly instant on -restart Very High Color Rendering Index Value (CRI) Low cost ballast system Disadvantages Low durability Medium rated efficiencyHigh Intensity Discharge Lamps (HID): High Intensity Discharge Lamps (HID) Mercury Vapor (Blue-White color): Mercury Vapor (Blue-White color) Advantages Least expensive discharge lamp Long Life Medium CRI (Coated lamps) Low cost ballast system Disadvantages Lower efficacy that HPS (High Pressure Sodium) Clear non coated lamps have a low CRI Long re-strike time when hotMetal Halide (Bright White color): Metal Halide (Bright White color) Advantages High initial efficiency Excellent white light source Very High CRI Temperature unaffectedMetal Halide (Bright White color): Metal Halide (Bright White color) Disadvantages High Cost Short Life Lamp to Lamp Color Variation High Cost ballast Require enclosed fixtures High Pressure Sodium (Amber color): High Pressure Sodium (Amber color) Most often used in urban applications Advantages High efficiency Low maintenance Good value Short restrike timeHigh Pressure Sodium (Amber color): High Pressure Sodium (Amber color) Disadvantages Low CRI Value Effected by temperature Cycles at end of life High ballast costLow Pressure Sodium (Orange color): Low Pressure Sodium (Orange color) Advantages Long life Excellent maintenance Mercury free High efficiencyLow Pressure Sodium (Orange color): Low Pressure Sodium (Orange color) Disadvantages Monochromatic (Nearly zero CRI Value) Not compact Slow warm up and restrike Light distribution is difficult to control (wrapping characteristic)Light Installation: Light Installation Lighting installations can be evaluated on the following simple guidelines: Does the light source have excessive glare which detracts from the light effectiveness and results in discomfort to the eyes? Does the light source annoy passing traffic, pedestrians and cause problems for adjacent properties? (Light pollution) Does the light cover the prescribed area with an adequate amount of light? Provide “corner covering” capabilities? (Proper light pattern distribution) (I to V rating) Is the light source unobstructed? (maintenance).Outdoor Light Source Types: Outdoor Light Source Types Pole Types:: Pole Types: Include wooden, cement, aluminum, cast metal, fiberglass.

Speed, traffic density, traffic volume and parking problems are mutual concerns of any neighborhood, sub-division or business district. Neighborhood Roadways: Neighborhood Roadways Neighborhoods and cities are developed along the following street pattern types: Linear–Most common in rural or undeveloped areas which use straight roadways with few intersecting roadways. Radial–Some neighborhoods or city districts have been developed using a wheel pattern of curving streets intersected by straight streets or spokes.Neighborhood Roadways: Neighborhood Roadways Grid Pattern–a plan using equidistant streets and avenues intersecting at 90 degree angles. Curvilinear–systems of curving streets and avenues usually named; not numbered and due to the difficulty and lack of an easily discernable pattern, require local knowledge to attain familiarity. These neighborhoods are usually considered less susceptible to high traffic volume, cut through traffic and problems associated with excessive traffic.Street Systems: Street Systems Private Residential Service Road Sub-collector Collector Arterial Limited Access InterstateDefinition: Definition Traffic Management–the modification if a roadway to make it less efficient at transporting large numbers of cars which travel at higher than residential speeds. Traffic management is seen as a long term way to re-direct traffic to more efficient thoroughfares and, in the process, restore a sense of livability and safety to neighborhoods that have become high speed commuter speedways. Broward County Traffic Management Manual Traffic Calming Devices–A toolbox of devices which may be employed to reduce vehicular speed on residential streets. Examples include speed humps, speed tables, round abouts, chicanes, pop-outs, neck downs, and any other device or tactic that can be used to reduce traffic speed in residential neighborhoods as well as discourage cut-through traffic. Broward County Traffic Management ManualComments by Dan Burden: Comments by Dan Burden “People fear traffic in residential areas because they sense the very real possibility of death. A vehicle traveling at 40 MPH that strikes a pedestrian will kill that pedestrian 80 percent of the time. At 30 MPH the chances of death are 50/50. A vehicle travelling at 20 MPH that comes into contact with a pedestrian will result in pedestrian death 5 percent of the time.” “Stop signs are not traffic calming devices. Stop signs punish the driver. Research shows that excessive and unnecessary placement of stop signs actually increases traffic speed as the driver races from sign to sign.”Comments by Dan Burden: Comments by Dan Burden “Neighborhoods which are built to the street, with sidewalks preferably separated from the street by grass and street parking on both sides of the street will naturally calm traffic and reduce fear.” “Short blocks with “T” intersections must be emphasized.” “The driver naturally drives at the speeds to which a roadway is designed, not to arbitrarily posted speed limit signs.” “A grassy median will cut down crashes on that roadway by 50 percent.”Comments by Dan Burden: Comments by Dan Burden “The issue of retrofitting traffic calming and traffic management happens in three steps. The first step is nothing works. The next is people start to consider traffic models that they have helped plan. The third step is the voting booth.” “Retrofitting trail systems into neighborhoods as linking tools encourage pedestrian and bicycle traffic as alternatives to neighborhoods which are sanitized of all commerce and require residents to drive to literally anything and everything.” “85 percent of the nation wants to live on a street with low traffic volume, low traffic speed and low traffic noise.”CPTED Interdisciplinary Teams: CPTED Interdisciplinary Teams Most teams strive to have members from the following areas of the municipal infrastructure. Planning and Zoning (coordinate with other “boards”) Traffic Engineering Energy Technology (lighting) Legal (drafting of new codes, code conflicts) Sanitation and Graffiti EradicationCPTED Interdisciplinary Teams: CPTED Interdisciplinary Teams Parks and Leisure Services (urban arborist, landscaper) Fire Codes Enforcement Building Review Services (building permitting) Neighborhood representatives and problem solvers Community Policing Law Enforcement ProfessionalsMonitoring and Evaluation of Objectives: Monitoring and Evaluation of Objectives Learning Objectives: Understand the importance of isolating issues and gaining consensus in the customer/citizen arena. Exploring voluntary compliance vs. codified forced compliance and the effects on the objective. Recognizing the clues when the ship is starting to sink. “Where is all this water coming from?” Organizing a team where all sides benefit from rowing the boat. Recognizing the critical times when issues are most likely to catch fire and using time to your advantage. Understanding when plans are unique or interchangeable. “Not in my neighborhood!”Organized Controls: Organized Controls Neighborhood Organizations Home Owners Associations Condominium/Apartment meetings Senior Groups Ethnically Centered Groups (German Club, African Club) Hobby ClubsOrganized Controls: Organized Controls Civic Organizations Business Area Organizations Girl Scout/Boy Scout and similar groups Church Organizations of all types including worship services Political Groups (Young Democrats, etc) Recreation activitiesThe Dangers of Being too Good at Sales : Overselling: The Dangers of Being too Good at Sales : Overselling “There is no greater enemy to the success of an idea, than those who vociferously promote it without the first notion of understanding” ...EdisonSuccessful Methods of Community Education: Successful Methods of Community Education Citizen ride along programs Citizen police academy Citizen volunteer road patrol Citizen volunteer programsEvaluating Results of Implementation Plans: Evaluating Results of Implementation Plans Implementation plans should ask important questions such as: Is the project necessary for the community and will the whole community benefit? What is the best way to communicate and educate the public on the benefits? Who are the stakeholders and who will be affected and inconvenienced? Are there time lines for implementation?Evaluating Results of Implementation Plans: Evaluating Results of Implementation Plans What type of authority or approval is needed to proceed? Media involvement: invited or uninvited? How do we involve the public in the planning process? Where will resistance and support come from? What are the real expectations of this project? Who will lead? Who will implement? Is real money needed and are there alternative monies available? You do not have the permission to view this presentation.
