| 宝鸡市火炬路与清姜路交叉口交通组织设计 摘 要：火炬路与清姜路交叉口位于宝鸡市渭滨区，新老城区交界处的交叉口，周边商业区和住宅区，行人与机动车的流量较大，公共交通在此较为密集，在宝鸡市的路网结构中占据重要位置。首先，本文对该交叉口的路口现状进行说明，通过调查得到交叉口的道路几何数据、交通信号配时等数据资料，以及通过交通工程理论资料结合计算得出交叉口现有服务水平后发现交叉口现有通行能力不能满足当前交通需求，再以此为基础，根据交通工程相关理论、国家标准和设计规范，结合实际情况，从优化交叉口渠化、更改信号灯配时、加入区域信号控制等方面，提出可行的交通组织设计方案；再利用Vistro交通分析软件分析设计前后的效果，对比设计方案对交叉口机动车通行能力的改善情况。 关键词：平面交叉口；交叉口渠化；交通仿真评价；信号配时；区域协调控制 Traffic organization design at the intersection of Torch Road and Qingjiang Road in Baoji City Abstract: Torch Road and Qingjiang Road intersection is located in Baoji Weibin District, the intersection of the old and new urban areas, the surrounding commercial and residential areas, the flow of pedestrians and motor vehicles is large, public transportation in this more dense, Baoji City road network structure occupies an important position. First of all, this paper shows the present situation and problems of the intersection of the intersection, the road intersection geometry is obtained by survey data, such as traffic signal timing data, and the calculated data by traffic engineering theory combined with existing intersection service level and found existing intersection traffic capacity can't meet the current traffic demand, and on this basis, According to the related theories of traffic engineering, national standards and design specifications, combined with the actual situation, from the optimization of intersection channelization, change the timing of signal lights, add regional signal control and other aspects of the feasible traffic organization design scheme is put forward. Vistro traffic analysis software was used to analyze the effects before and after the design, and to compare the improvement of the vehicle capacity at the intersection by the design scheme. Key words: Plane intersection; Intersection channelization; Traffic simulation evaluation; Signal timing; Area coordinated control |
