信号优先和车地通信系统在现代有轨电车中的应用

Application of Signal Priority and Train/Ground Communication in Modern Tramcar Project

近年来,现代有轨电车的发展十分迅速。信号优先和车地通信系统在技术上日臻完善,是现代有轨电车提高服务水平的关键因素。信号优先可以根据公交运营计划、社会交通状况、路口通行条件,给予不同的信号优先级别,甚至转为人工干预控制。通过介绍信号优先和车地通信系统的原理,对优先控制方案和车地通信技术进行了比较分析。

The development of modern tramcar is very rap- id in recent years, the technology of signal priority and train/ground communication are approaching perfection and have become the key for modern tramcar service im- provement. The strategy for signal priority could be classi- fied into different priority levels according to the operation schedules, traffic conditions and intersection status, some- times could be ever turned into manual intervention. In this article, the system principle of signal priority and train/ ground communication are introduced, different technolo- gies and solutions of control priority and train/ground com- munication are comparatively analyzed.
