A Structural Model of Peak-Period Congestion: A Traffic Bottleneck with Elastic Demand.

This paper considers the modeling of road congestion subject to peak-load demand. The standard model contains ambiguities and is poorly specified. These problems can be eliminated by working with a structural model that explicitly treats the congestion technology and drivers' behavioral decisions. The paper provides a detailed analysis of a particular structural model--William Vickrey' s model of bottleneck congestion in the morning rush-hour auto commute extended to treat elastic (i.e., price-sensitive) demand--and examin es some economic implications of the structural approach.
