| Abstract: | This paper presents a novel reliability-based stochastic user equilibrium traffic assignment model in view of the day-to-day
demand fluctuations for multi-class transportation networks. In the model, each class of travelers has a different safety
margin for on-time arrival in response to the stochastic travel times raised from demand variations. Travelers' perception
errors on travel time are also considered in the model. This model is formulated as an equivalent variational inequality problem,
which is solved by the proposed heuristic solution algorithm. Numerical examples are presented to illustrate the applications
of the proposed model and the efficiency of solution algorithm. |
