A dynamic traffic assignment model of car and bus travel under road pricing

A road-pricing scheme with the objective of diverting travelers from the private car mode to the bus mode is proposed. The plan is to set up some tolling points on roads used by buses and cars. Compared to bus only lanes it is more flexible because it allows the road capacity that are allocated to buses to be more finely adjusted. A case study highway network with six at-grade signalized junctions and four OD pairs is used. A cyclic bus line is operated. A simulation-based dynamic traffic assignment model is developed to determine the modal choice and route choice of the travelers
