COMPARISON OF THREE METHODS FOR DYNAMIC NETWORK LOADING
The main approaches used to model traffic dynamics are microscopic simulation models which move vehicles according to behavioral car-following and plane-changing models along prescribed routes. This paper considers the dynamic network loading problem, where time varying demands on paths of the traffic network are given. Three methods for solving the problem are compared, based on analytical approaches, the cell transmission model, and a space queuing approach. The microscopic simulation model INTEGRATION is used to provide a benchmark for the comparisons. The numerical example chosen for experimentation is described before presenting the results obtained with each method.
