Route Choice Modeling without Route Choice

This paper presents and tests a dynamic discrete choice approach for the estimation of the parameters of a route choice model. In the dynamic modeling approach, the individual is seen as taking sequential decisions on which link to choose, and the choices are made at the nodes in the network. The obvious advantage with this approach is that the choice set at every stage is quite small and well-defined, while a correlation structure may be imposed among different paths, even if each sequential decision follows a multinomial logit model. The complexity of estimating dynamic discrete choice models lies in the fact that a dynamic programming (DP) problem needs to be solved for each trial value of the utility parameters. Research shows that an approximation of the DP problem is sufficient to obtain consistent parameter estimates. The authors present numerical results for a real network (Borange, Sweden) where the authors compare exact value functions from synthetic data with approximations. For this model specification the authors obtain consistent parameter estimates using the approximated value functions. The authors also present some preliminary estimation results based on real observations for the same network and the results are very promising.
