I ran across this interesting graphic in the Victoria Transport Policy Institute’s report titled “Valuing Transit Service Quality Improvements“, by Todd Alexander Litman (2007). From the Abstract:
This report investigates the value travelers place on qualitative factors such as comfort and convenience, and practical ways to incorporate these factors into travel time values for planning and project evaluation. Conventional evaluation practices generally assign the same time value regardless of travel conditions, and so undervalue comfort and convenience impacts. Yet, a quality improvement that reduces travel time unit costs by 20% provides benefits equivalent to an operational improvement that increases travel speeds by 20%. This report recommends specific travel time value adjustments to account for factors such as travel and waiting comfort, travel reliability, and real time transit vehicle arrival information. It describes how service quality improvements can increase transit ridership and reduce automobile travel.
The walking and cycling numbers really jumped out at me. The report is written for transit planners, so it naturally focuses on getting people out of cars and onto public transit, but I was surprised that the ped/bike numbers were virtually ignored in the document text. It would have been nice to see a column for Mixed (Cycling & Transit), my usual mode. It’s interesting that Automobile Only fared better than Transit Only, but the two combined fared the worst.
So what does all this mean? Ride your bike to work and be happy! :-)
