In commenting on an earlier thread Paul H cited a graphic showing how the Chinese know what the short-run travel times are in a vast city like Beijing.  It is apparently based on the (real time) travel times of 10,000 taxis in the city. It provides a guide to instantaneous marginal congestion costs based on information from GPS [...]

The resulting excess demands are rationed primarily by restrictions on the [...]

This creates what is the most significant externality associated with road travel. For the UK congestion is estimated by Samsom et al. (2001) to provide between 75-84 per cent of total [...]
