摘　　要：车辆的增加给城市道路交通带来了压力,尤其是在不同交叉口距离较近时,更易出现交通拥堵、事故频发现象。文章通过TruckSim软件建立模型,依托道路主干道交叉路口实际工程,分析了城市道路平面交叉口优化设计措施与评价方法。结果表明,优化城市道路平面路口的过程中,应按照交通分离、均衡通行压力、方便出行的原则进行优化;采取相关优化措施前后,行车轨迹误差最大值由0.252 m降至0.211 m,优化率为16.2%;优化后的路口采用垂直设计,降低了行车轨迹误差,提高了行车安全。The increase of vehicles has brought pressure to urban road traffic,especially when the distance between diff erent intersections is close,traffic congestion and frequent accidents are more likely to occur.The model is established by TruckSim software,and the optimization design measures and evaluation methods of urban road grade intersection are analyzed based on the actual engineering of main road intersection.The results show that in the process of optimizing the urban road grade intersection,it should be optimized according to the principles of traffic separation,balanced traffic pressure and convenient travel;before and after relevant optimization measures are taken,the maximum error of driving trajectory is reduced from 0.252 m to 0.211 m,and the optimization rate is 16.2%;the optimized intersection adopts vertical design,which reduces the driving trajectory error and improves the driving safety.
