Abstract So far most combined-modal traffic assignment models do not consider the influence of travel time reliability on travel behavior. Due to this reason this paper constructed a combined-modal traffic assignment model based on travel time reliability. This model took into consideration the stochastic factors of network in combined-modal travel behaviors, thus better depicted the model & route choice behavior. The algorithm was designed based on K-shortest paths algorithm coupled with the method of successive averages. Further the application of the proposed model and the algorithm were illustrated using real network of Shanghai North Bund. The results were compared with traditional models which do not consider the impact of reliability factors. This paper analyzed the effect of P&R policy on reducing traffic congestion and improving the link travel time reliability, and clarified the three-dimensional relationship among the rate of travel demand of two modes, reliability preference factor and travel demand utility factor.
