Abstract:Traffic engineers use transport models to predict future traffic streams. The route choice model is an important step of the transport model. We observe unrealistic routes in the results of the transport models used at DHV. But DHV has never calibrated or validated their transport model with regard to the route choices. From all the steps of the transport model we expect the biggest improvement of the transport model by improving the route choice model. DHV often uses the shortest route principle. We investigate literature for other route choice models. We found several promising route choice models besides the shortest route principle. We select the most promising route choice models on the basis of: reality, computational time, and ease of use. The C-logit and the game theory based route choice models are realistic route choice models with reasonable computational time, and are easy to use due to earlier experience with these approaches. We select both approaches for further investigation. Within the C-logit we vary different parameter values, including the scale parameter. We vary the scale parameter, because we proved that the C-logit results depend on the utility scale. The games of game theory we use are the congestion game, the demon player game, the smooth fictitious play under the Multinomial logit rule, and the smooth fictitious play under the C-logit rule. In literature, the smooth fictitious play is only described under the Multinomial logit rule. We verify the use of the C-logit by a proof of convergence of the smooth fictitious play under the C-logit rule. We formulate our research goal to investigate these two route choice model approaches: Investigate whether route choice models based on C-logit and game theory are able to produce more realistic route choices than the shortest route principle, and investigate the behavior of the C-logit and game theory models.
