摘　　要：PRT个人捷运交通系统为无人驾驶功能的新型交通系统,具备乘坐舒适、搭乘便捷、较低建设成本、较低运营成本的优点。PRT系统由小型车辆及其专用走行线路组成,将传统"人等车"的理念转变为"车等人"。文章分析了适用于PRT车辆的专用自动防护系统(AVP系统),其独立于PRT的中央控制系统,利用物理块原理实现车辆自动防护及防撞,确保所有车辆在线路上有序运行,确保车辆无追尾、碰撞等安全事故发生,确保车辆在线路交汇处安全有序通过。文章从AVP系统的结构组成、信号时许、可靠性分析入手,可为后续PRT工程提供参考。PRT is short for personal rapid transit,which is a new type of transportation system with driverless function.PRT system has the advantages of comfortable riding,convenient riding,low construction cost and low operating cost.The PRT system consists of small vehicles and their dedicated routes,transforming the traditional concept of people waiting for cars into cars waiting for people.This paper analyzes the special automatic vehicle protection(AVP system)for PRT vehicles,which is independent of PRT the central control system,using the physical block principle to realize automatic vehicle protection and anti-collision The system makes all PRT vehicles run orderly on the straight and branch guideway,so as to ensure that there is no collision,speeding and other unsafe accidents.This paper starts from the structure composition,signal timing and reliability analysis of the AVP system,which can provide references for subsequent PRT projects.
