Development of a Visual Simulator for Traffic Flow/Safety Analysis at Railway Crossings

摘要

From a systems point of view, railway crossings are the weakest point in the railway system, accounting for a major part of fatal railway operational accidents in spite of several countermeasures taken, and as always, high priority continues to be given to safety countermeasures. With a view to more effective and elaborate prevention, we have developed a simulator using a personal computer to analyze complicated traffic situations near a railway crossing caused by train/road traffic, crossing installation etc. The simulator is aimed at reproducing visually, real-time and conveniently the traffic conditions such as traffic jam or accidents, thereby evaluating safety, effects of equipment improvement and control of gate and alarm, and eventually contributing to establishment of proper standards for signal design.
