MODELING DYNAMIC TRAFFIC ASSIGNMENT MODEL TO SATISFY FIFO (FIRST-IN-FIRST-OUT) WITH TWO VEHICLE CLASS TRANSPORT NETWORKS

Methods of performing dynamic traffic assignment are needed to simulate traffic conditions on urban highways during peak periods of congestion for traffic control or transport demand management. Dynamic traffic assignment model considering two vehicle types is developed in this paper. This model is based on user optimum. Link outflow is one of the basic variables used to describe the dynamic link state in dynamic traffic assignment problems. To calculate link outflow at each instant, appropriate link exit function is necessary, and therefore, it becomes one of the most fundamental functions in dynamic traffic assignment problems. On the other hand, first-in-first-out discipline (FIFO) is regarded to be a basic rule for any traffic assignment problem. In this paper, FIFO rule is formulated for each vehicle type first. Then, link exit function is formulated according to the definition of link travel time and FIFO rule. Investigators also prove that the link exit function formulated in this paper can satisfy FIFO rule. The link exit functions are certified by practical examples. The evaluation results reflect that the link exit function formulated in this paper can calculate link outflow correctly. In this model, car can outrun heavy vehicle. The developed model is applied to Nagoya's road traffic network to research the feasibility and efficiency.
