Modelling Stochastic Route Choice Behaviours with a Closed-Form Mixed Logit Model

الملخص EN

A closed-form mixed Logit approach is proposed to model the stochastic route choice behaviours.

It combines both the advantages of Probit and Logit to provide a flexible form in alternatives correlation and a tractable form in expression; besides, the heterogeneity in alternative variance can also be addressed.

Paths are compared by pairs where the superiority of the binary Probit can be fully used.

The Probit-based aggregation is also used for a nested Logit structure.

Case studies on both numerical and empirical examples demonstrate that the new method is valid and practical.

This paper thus provides an operational solution to incorporate the normal distribution in route choice with an analytical expression.
