城市快速路交叉口运行的VISSIM仿真评价

通过实地交通调查后对数据的整理和分析,发现交通拥堵的城市快速路交叉口,对其进行交通组织优化,缓解其拥堵状况,疏散拥堵的交通。在取得了大量的基本数据和资料并进行整理分析后,对具体交叉口进行道路交通优化组织,对交叉口的交通现状进行仿真,得到交叉口存在的交通拥堵问题根本原因,提出改善措施。通过对交叉口交通状况前后仿真数据进行评价分析,为科学进行交叉口改善设计提出量化依据。

VISSIM simulation evaluation design of city expressway intersection

This paper has operated the traffic survey,collected and analyzed the data,found the congestion of the road and optimized it,alleviated the congestion,evacuated the traffic jams.Taking real intersection as example,this paper records the traffic flow and timing control,analyzes traffic condition.At the last,this study simulates the traffic operation status under the present condition with traffic simulation software VISSIM and improves the signal timing.
