城市轨道交通作为一个复杂系统，由基于车－地双向通信的列车运行自动控制系统来保证运营安全。为了弥补普遍应用的列车控制系统过度依赖地面控制中心和车－地通道的不足，提出一种新型的城市轨道交通碰撞防护系统（CA-SUMT），该系统叠加于既有列车运行控制系统之上，基于“车－车通信”技术实现列车碰撞防护。设计列车碰撞防护系统总体结构和工作原理，并详细研究系统的关键技术；通过合理简化，并对系统的可靠性与安全性进行建模分析对比，研究结果表明：增加碰撞防护系统的城市轨道交通列车运行控制系统可有效提高运营效率，保障运营安全。

Automatic train control system (ATC)based on train-trackside radio communication can guarantee the safety of urban mass transit.To overcome the shortcoming of ATC and radio based train control (RBTC)'s o-verly dependence on trackside control center and train-ground communication system,a new safety-increasing system strategy for train control system,collision avoidance system for urban mass transit (CASUMT),which is based on the vehicle-vehicle communication technology to prevent train collision was introduced in this paper. We also designed the overall system structure and working principle to investigate the key technology of the new system in detail.Through reasonable simplification of the communication system,this paper modeled the reliabil-ity and safety of the improved ATC overlay collision avoidance system and traditional ATC.The contrasting re-sults show that the improved train control system by adding collision avoidance system is more effective and safe.
