Using path decomposition enumeration to enhance route choice models

Observing Unobserved Heterogeneity: Using Process Data to Enhance Choice Models

Analyzing how travelers choose scenic routes using route choice models

Finding a scenic route between two locations is a common trip planning task, in particular for tourists and recreational travelers. For the automated computation of a scenic route in a trip planning system it is necessary to identify which attributes of a route and its surroundings are associated with attractive scenery. This study uses a route choice model, more specifically a Path Size Logit ...

Evaluation of choice set generation algorithms for route choice models

This paper discusses choice set generation and route choice model estimation for large-scale urban networks. Evaluating the effectiveness of Advanced Traveler Information Systems (ATIS) requires accurate models of how drivers choose routes based on their awareness of the roadway network and their perceptions of travel time. Many of the route choice models presented in the literature pay little ...

An Alternative Approach to Route Choice Simulation: the Sequential Models

On the other hand, path choice is a very complex context to be simulated because of the above mentioned large number of alternative paths and of their overlapping which, within the random utility (RU) theory, means correlations among utilities. This complexity suggests the use of demanding models (like the Probit model) without a closed form which require simulation methods, thus inducing high ...

Decomposition of Path Choice Entropy in General Transport Networks

This paper shows that the LOGIT type stochastic assignment / stochastic user equilibrium assignment can be represented as an optimization problem with only link variables. The conventional entropy function defined by path flows in the objective can be decomposed into a function consisting only of link flows. The idea of the decomposed formulation is derived from a consideration ofthe most likel...
