呼和浩特火车站交叉口交通组织优化分析研究

Study on the organization of Hohhot railway station signalized intersection

针对呼和浩特火车站交叉口的交通组织方式和信号配时进行实地调查,并对当前组织方式下的交通运行状况进行分析,以车辆安全畅通运行及延误时间短为目标,提出适合该路口交通条件的提前放行左转的保护加许可型信号配时优化方案,并应用synchro进行仿真,仿真结果表明该优化方案有效提高了交叉口通行能力且降低了延误时间。

The paper analyzed the present channeling and signal timing of the traffic organization methods by the field survey on Hohhot railway station intersection,and studied traffic operational conditions under the present situations.In order to vehicles operate safely and reduce control delay,this paper proposed protected-plus-permitted phasing left-turn operation and using synchro simulation system to optimize.The result of simulation express that the plan of the optimized traffic organization can improve the capacity of the level signalized intersection and reduce control delay time.
