Just what are the Benefits of Cycling Projects?: 

Just what are the Benefits of Cycling Projects? Glen Koorey Principal Researcher, Traffic Engineering & Road Safety Opus Central Laboratories, Lower Hutt

Introduction: 

Introduction What is a "Cycling" Project? Transfund Procedures Standard Benefits Other Benefits & Problems

What is a "Cycling" Project?: 

What is a "Cycling" Project? Traditional: Cycleways (off-road) Cycle lanes (on-road) Intersection markings/signals Cycle Parking facilities

What is a "Cycling" Project? cont'd: 

What is a "Cycling" Project? cont'd Revised: ANY Works that Benefit Cyclists Traffic Management / Calming Shoulder Widening Removal of Path Barriers "Pedestrian Improvement" Projects Regular Shoulder Clearing/Sweeping

Transfund NZ Funding: 

Transfund NZ Funding Funds Roading Projects "Benefit/Cost Ratio" > 4 State Highways fully funded Local Roads ~50% funded Also funds "Alternatives to Roading" (ATR) Projects Cycling included in Roading projects

Transfund Benefit Calculations: 

Transfund Benefit Calculations Calculated over 25 Years from Construction Future Year $$$ "discounted" to Present Value Standard Benefits detailed in Project Evaluation Manual (PEM) Hard to justify non-PEM Benefits

Travel Time (TT) Benefits: 

Travel Time (TT) Benefits Standard $Cost per hour of Travel Differs with Vehicle Type, Trip Purpose Transfer Trips from Motor Veh to Cycle Slower  More Cost? Benefits depend on Congestion "Short Cut" Routes for Cyclists TT Savings over previous Road Route Barrier Removal speeds up Trips

Veh Operating Cost (VOC) Benefits: 

Veh Operating Cost (VOC) Benefits Standard $Cost per km of Travel Differs with Vehicle Type, Road Grade, Vehicle Speed, Road Roughness NO Cyclist VOC costs in PEM Mode shift should save costs No Benefit from Cycle "Short Cuts"

Accident (Crash) Benefits: 

Accident (Crash) Benefits Most common Cycling Project benefits Standard $Cost per recorded crash Differs by Severity, Vehicle Involved, Crash Type, Speed Limit Crash numbers scaled up by "Under-reporting" factors Cycle-only crashes may still be under-represented Need to have SOME Crash History

Example: Petone-Ngauranga Cycleway: 

Example: Petone-Ngauranga Cycleway 1996-2000 (5 years): 10 crashes on SH2 1 Fatal, 3 Serious, 4 Minor, 2 Non-Inj Total Cost of Crashes over 25 years: $5.84 million Assume: 80% Reduction in Southbound Crashes 60% Reduction in Northbound Crashes Predicted Cost of Crashes: $1.48 million over 25 years Saving: $4.36 million

Other PEM Benefits: 

Other PEM Benefits Environmental CO2 & Other Emissions Noise Reduction Ground Vibration Social Severance Site-Specific Discomfort Reduced Maintenance Costs

Benefits Not Specified: 

Benefits Not Specified Physical Health Benefits Urban Speed Reduction Only TT Disbenefits No Standard Safety Benefits Perceived Risk Improvement Use of Typical Crash Rates Security Benefits for Parking Facilities Intangible "Willingness to Pay" (WTP) for Cycling Projects

Other Problems: 

Other Problems Modal Shift Effects How many people will switch to Cycling? Trip Generation Demand How many new people will take up Cycling? Cycle Count Data Typical Crash Savings of Facilities Network/Strategic Evaluation of Projects
