摘　　要：因进路计轴区段的占用/出清等限制,CBTC系统站后折返能力存在瓶颈。TACS突破了联锁进路限制、精简了系统架构、弱化了轨旁设备,是信号系统新的发展方向,故深入研究TACS折返效率,以进一步提高系统性能和运营效率。着重分析TACS道岔区段线路资源申请过程和特点、线路资源管理特殊场景及建模过程;以蓝村路站折返作业为例,分析对比TACS、CBTC折返作业过程中线路资源申请、释放的区别;结合上海4号线实际土建参数和车辆参数,进行系统折返能力仿真验证。结果表明,TACS系统折返能力相较于传统CBTC系统提升了18%,有效提高了系统站后折返效率。Due to the occupancy/clearance of axle counter section within the route,there is a bottleneck in the turn-back capability of CBTC system.The train autonomous control system(TACS)breaks through the limitations of interlocking route,simplifies the system architecture,and weakens the trackside equipment,which is a new development direction of signal system.Therefore,it is necessary to study the TACS turn-back efficiency to further improve its performance and operation efficiency.The process and characteristics of line resource application in TACS switch section,the special scene of line resource management and the modeling process are emphatically analyzed.Taking the turn-back operation of Lancun Road Station as an example,the difference between the application and release of line resources in the process of TACS and CBTC turn-back operation is analyzed and compared.Combined with the actual civil engineering parameters and vehicle parameters of Shanghai Line 4,the simulation verification of the system turn-back capability is carried out.The result shows that the turn-back capability of the TACS system can be increased by 18%compared with the traditional CBTC system,which effectively improves the TACS's turnback efficiency.
