ANALYSIS OF PEAK PERIOD TRAFFIC CONGESTION WITH ELASTIC DEMAND

This paper presents a dynamic model of peak period traffic congestion that considers a limited number of bottlenecks. The model predicts the temporal distribution of traffic volumes with an elastic demand model. In response to changes in the traffic conditions travellers can switch to a different mode, divert to an alternate route, or shift the trip forward or backward in time to avoid a long delay. A simple example would be the case of two parallel routes with travellers jointly selecting route and departure time. The choice of route and mode are dependent on travel times and travel costs. The choice of departure time is based on the tradeoff between travel time and schedule delay which is the difference between the actual and the desired arrival times. The delays at the bottlenecks are modelled with a deterministic queueing model that determines waiting time as a function of the length of the queue at the time of arrival at the bottleneck. The day to day adjustment of the distribution of traffic is derived from a dynamic Markovian model. Numerical simulation experiments are used to demonstrate the possible changes in the pattern of peak period congestion when a bottleneck capacity is changed.
