The 21st Century Truck – Safety, Security, Environmental, and Efficiency Challenges : 

The 21st Century Truck – Safety, Security, Environmental, and Efficiency Challenges Robert M. Clarke President, Truck Manufacturers Association AASHTO Subcommittee on Highway Transport Annual Meeting Cleveland, Ohio June 10,2004

TMA Members: 

TMA Members Ford Motor Co. Freightliner General Motors Corp International Truck and Engine Corp. Isuzu Commercial Motors Mack Trucks Inc. PACCAR Volvo Trucks North America

Average Annual Sales, 2000-02: 

Average Annual Sales, 2000-02

In-use Truck Population (US Census, VIUS 97): 

In-use Truck Population (US Census, VIUS 97) Classes 1-2 – 68,100,000 Classes 3-5 -- 1,435,000 Class 6 – 729,000 Classes 7-8 – 2,535,000 Over 600,000 Motor Carriers (2002) – 75% Operate 6 or fewer Vehicles

Key Issues the Industry Faces: 

Key Issues the Industry Faces Environment EPA 2007/10 Emissions Standards Efficiency/Productivity Fuel Efficiency Asset Utilization Safety Crash Avoidance Crash Protection Security Locating/Tracking


Environment By 2010, Particulates and NOx will have been reduced 99% from 1980’s levels Significant Technology Advances in Fuel and Air Management, and Exhaust Aftertreatment will be Necessary Availability of Ultra-Low Sulfur Diesel Fuel (>15ppm) critical for post 2007 vehicles Engine and Truck Manufacturers on Track for Successful 2007 Introductions

Productivity/Asset Utilization: 

Productivity/Asset Utilization Store and/or Broadcast Management Information On-Board Diagnostics/Prognostics Driver Work/Rest Scheduling Enroute Dispatching, Vehicle Location, Cargo Tracking Fuel Tax Reporting Mileage Patterns

Productivity/Asset Utilization: 

Productivity/Asset Utilization Possible Advent of Truck-Only Lanes, Coupled with Increasing Freight Demand Invites Reasoned Consideration of Larger, Safer, More Fuel-Efficient Trucks TRB 267 Study Results are an Excellent Basis for Renewed Deliberations

Safety – Crash Avoidance: 

Safety – Crash Avoidance Braking Control Systems On-Board Performance Monitoring Intelligent Collision Avoidance Systems Lane Change Rear-end Lane Keeping Driver Displays

Safety – Crash Avoidance: 

Safety – Crash Avoidance Lighting/Signaling Stopped Vehicle Warning Intelligent Forward Lighting/Glare Tractor-to-Trailer Control and Communication Tires Tire Pressure Monitoring Traction Handling/Stability/Maneuvering Rollover Turning/Offtracking

Safety - Crash Protection: 

Safety - Crash Protection Truck Drivers 21 fatalities/100K drivers in 2002, National Avg. = 4/100k workers (NIOSH data) Rollovers and Ejection are Predominant Cause Seat Belt Use only 49% Seat Belt Comfort an Issue

Safety- Crash Protection: 

Safety- Crash Protection Occupants of Other Vehicles Involved in Collisions with Trucks Largest Portion of Overall Heavy Truck Safety Issue – 79% of all truck crash fatalities in 2002 Actions of Drivers of Other Vehicles Most Frequently Precipitate These Collisions Crash Impact Attenuation Opportunities Conceivable, but are Stymied by Size and Weights Limitations


Security Electronic Vehicle Entry Driver Identification, Verification Cargo Identification, Tracking, Monitoring Smart Cargo Seals Vehicle Geo-Fencing, Tracking Enroute Navigation, Communication, Remote Vehicle Control

Summary – The Long Term View: 

Summary – The Long Term View Continual Social and Economic Pressure to Reduce Emissions, Fuel Use and Crashes Medium/Heavy Trucks will Continue to Rely on Clean Diesel for the Foreseeable Future ITS Technologies have Great Potential in all Key Issue Areas. Integrated, Multi-Function Systems are the Key to Costs and Acceptance

Summary – The Long Term View: 

Summary – The Long Term View Fewer, More Productive, Advanced Technology Trucks – Capable of Performing Well in Challenging Traffic Environments, are a Possible Key to Improving Safety, Emissions, and Fuel Use Federal/State Relationship with Vehicle Mfgs and Users Predominantly Regulatory. Positive Relationships would be Welcomed Proactive Leadership, Especially in Technology Demonstration and Fleet Testing, Needed to Achieve Accelerated Widespread Use of Advanced Technologies
