A Combined Approach of Microscopic and Macroscopic Simulation for Rail Traffic

Abstract

This paper presents a combined approach of rail traffic simulation using suitable models both microscopic and macroscopic. In rail traffic, the train motions do not directly depend on the preceding train motions like road traffic, but only depend on the code speed in the block section belonging at the present time. Using the history of the code speed in each block section, the simulation of each train running between stations can be performed independently. Based on this fact, we have formed a new microscopic model and proposed a combined approach applying the macroscopic model to normal train runs and the microscopic one to others. Our combined approach makes it possible to get quick responses of macroscopic simulation and detailed results of microscopic one.
