摘　　要：受信号控制和安全限速的影响,有轨电车在交叉口需要频繁制动。由于距离判断的不准确,有轨电车司机倾向于在交叉口预留一定冗余制动距离,以较低的制动系数制动,导致运行车速的下降。为减少冗余制动距离,提高车速,提出一种基于路侧固定标识的有轨电车交叉口制动引导方法,通过轨旁固定标识标记有轨电车起始制动位置和速度,从而引导司机以最短制动距离进行制动。开发了基于车辆动力学模型的有轨电车驾驶模拟系统,基于VISSIM实现仿真场景的创建。实验表明:该方法规范了司机的制动行为,提高了制动效率并减少了制动操作的随机性,对提高有轨电车的运行速度,改善运行时间的稳定性具有正面效用。Trams need to brake frequently due to signal control and safety speed limits at intersections.Due to the inaccuracy of distance judgment,tram drivers tend to reserve extra braking distance at intersections,resulting in lower braking coefficients and a decrease in speed.An intersection braking guidance method using lineside signs is proposed for trams to reduce braking distance redundancy and improve running speed.Drivers are guided to brake with the shortest possible distance by marking the initial braking position and speed of trams with fixed lineside signs.A tram driving simulation system was developed based on a vehicle dynamics model.Simulation scenarios were then created using VISSIM.The driving simulation experiments show that this method standardizes the driver's braking behavior,improves braking efficiency,reduces the randomness of braking operations,and therefore has a positive effect on speed improvement and time stability.
