An environmental cost model for travel time differences between bicycles and cars

What is the environmental cost of choosing to travel by car rather than by bicycle given complete modal interchangeability? Firstly, travel times on selected arterial roads have been collected for motorized vehicles in Adelaide and other major cities in Australia for many years. The routes surveyed and the times of travel (in the AM peak, inter-peak and PM peak) are set by in conjunction with local road authorities. Secondly, the University of South Australia’s Thinking on Two Wheels Cycling Research Program has funded the collection of travel time data by bicycle on the same Austroads routes as the cars and starting at the same times. Discovering the true environmental cost of the travel time differences entails consideration of many factors. This paper reports on the first stages of development of an environmental cost model that uses the empirical travel time differences, and car manufacturers’ published emissions data to give an estimate of the costs measured in terms of carbon dioxide-equivalent emissions per minute of travel time saved. The model presented applies to a single person who decides to drive a car rather than to cycle. (a) For the covering entry of this conference, please see IRRD abstract no. E216409.
