江东路隧道交通组织设计与路网可靠度研究

Study on Traffic Organization Design and Road Network Reliability of Jiangdong Road Tunnel

为了给城市阳台建设提供宝贵的土地资源,位于城市阳台景观带的江东路以下穿道路的形式建设,因此对江东路隧道的交通组织设计和路网可靠度进行研究。通过对5个现状交叉口交通流量的调查,对现状交通进行了评价。在此基础上对江东路隧道项目进行了交通组织设计,并通过路网可靠度研究得出了隧道建成前后岙滩片区道路网络结构的稳定性结论。结果表明:江东路隧道建成后,岙滩片区南北通向路网系统可靠度从73.8%大幅度提高至92.6%,有效提高了整个岙滩片区的通行能力。

In order to provide the valuable land resources for the construction of urban balcony,Jiangdong Road located in the urban balcony landscape zone will be constructed in the form of underpassing road.Therefore,the traffic organization design and road network reliability of Jiangdong Road Tunnel are studied.Through the investigation of the traffic flow at five current intersections,the current traffic is evaluated.On this basis,the traffic organization design of Jiangdong Road Tunnel Project is carried out,and the stability conclusion of the road network structure in Aotan District before and after the tunnel construction is obtained through the study on road network reliability.The results show that the reliability of the north-south road network system in Aotan District has been greatly increased from 73.8%to 92.6%after the construction of Jiangdong Road Tunnel,which has effectively improved the traffic capacity of the whole Aotan District.
