Path Choice Models in Stochastic Assignment: Implementation and Comparative Analysis
Abstract
In assignment models, a key role is played by the path choice simulation that evaluates the path chosen by users in relation to the perceived paths and relative costs. This study deals with the effects of the implementation of some most adopted path choice models (Logit, Weibit, Probit, and Gammit) within a Stochastic User Equilibrium assignment procedure. Some considerations on parameters needed to make results comparable and the method used to estimate them are also suggested some extensions based on Weibit model are proposed. Results obtained both on a test network and on a real one are reported.
