摘要
为缓解四平路周边交通拥堵状况,对四平路周边路网结构进行优化研究。通过对四平路周边现状用地情况、现状路网结构进行分析,提出周边路网进行优化的改造方案以达到减缓交通拥堵的目的,最后利用宏观交通软件TransCAD进行建模,从宏观角度分析四平路交通运行状况的改善效果,及路网完善后区域交通拥堵状况的改善。通过模型运行结果可知,对四平路沿线相交及平行道路进行扩容或者辟通后,四平路交通流量得以疏散,四平路流量总体上有一定程度的降低,对四平路沿线的拥堵状况改善起到很大作用。
In order to alleviate traffic congestion around Siping Road, this paper researches on optimizing the structure of road network around Siping Road.Based on the analysis of the present situation of land use and road network around Siping Road, this paper puts forward an optimized road network to relieve traffic congestion. Finally, the macro traffic software TransCAD is used to model, and the improvement effect of traffic operation condition of Siping Road and regional traffic congestion condition after the improvement of road network are analyzed from the macro perspective.Through the results of model operation, it can be seen that the traffic flow of Siping Road can be evacuated and the traffic flow of Siping Road decreases to a certain extent after the expansion or opening of intersecting and parallel roads along Siping Road, which plays a great role in alleviating the congestion situation along Siping Road.
