STUDY ON TRANSPORTATION DYNAMIC SIMULATION MODEL ON THE URBAN EXPRESSWAY

The Metropolitan Expressway Public Corporation and other administrative agencies have applied the static traffic assignment method to prediction of future traffic conditions. This method is in the approximately completed stage theoretically, and an efficient calculation method has been developed. On the other hand, the greatest problem in Metropolitan Expressways is traffic congestion. Prediction of future traffic jam conditions is needed. The traffic flow in a congested condition is essentially non-steady, making it difficult to use the traffic assignment method to reproduce traffic flow, including traffic jams. A dynamic approach is needed for this. There are many studies related to dynamic analysis of the traffic flow. Dynamic analyses may be classified into several categories. The problem of dynamic traffic assignment among them is categorized into an approach through mathematical analysis and an approach using a simulation model. The former has merits such as the definite meaning of objective function. However, this approach suffers difficulties in application to multiple start and end points. At the present time, practical application is difficult. Examples of the simulation model practically applied to the Metropolitan Expressways include the input/output method and SOUND (Simulation model On Urban Networks with Dynamic route choice). SOUND is a micro simulation with endogenous route selection. It is considered to be suitable for prediction of traffic conditions when a new route is provided for service. The author and others developed and verified a simulation model called TRANDMEX (TRANsportation Dynamic Model on urban EXpressway), which is an improved version of SOUND, to adapt to practical business. This study discusses the improvement of speed reproducibility that has been a problem to be solved in TRANDMEX. (a) For the covering entry of this conference, please see ITRD abstract no. E204151.
