Abstract:
In this note we extend the mixed mode logit model for intermediate destination choice to a similar model in which an explicit capacity is associated with each intermediate destination. This leads to a more realistic approach for modeling park&ride trips, since (in contrast to Kiss&Ride trips) the capacity of an intermediate zone is limited by the parking capacity it offers. We first show that this model can be expressed as a convex minimization problem. Then we look at the dual formulation and show that it can be solved efficiently with a coordinate descent method. A solution algorithm is proposed and its properties are discussed in detail. Finally, special attention is given to the practical aspects of applying such a model for real life projects, and a general implementation of the model in the form of a macro for the EMME/2 transportation planning package is outlined.
