True cost of road travel

摘要

A key strategy in achieving sustainable transportation is the full cost charging regime for the motorists. However, the development of rational and fair charging policies must be based on the recognition of true externalities that are currently not paid for by the motorists. This research has revealed that contrary to common belief, the external components of the highly publicized community cost of accidents and congestion are insignificant. However, the environmental impacts of transportation are significant and very little of this cost is recovered from the motorists. This finding is useful for developing full cost charging system.
