Implementation Issues of Route Choice Models in Path-Based Algorithms (original) (raw)

Few of the recently developed route choice models have actually been applied in traffic assignment models. This paper discusses the implementation of selected route choice models in stochastic user equilibrium algorithms. The focus of the paper is on path-based algorithms, since they are essential in the implementation of route choice models. The paper analyzes the effect of choice set size and selected choice models on problem convergence, running time and selected results. The results presented in the paper indicate that for real-size networks, it is needed to generate a large number of alternative routes; in addition, convergence properties greatly increase if the generated routes are sufficiently disjointed.
