主辅分离道路在窄路密网模式中的应用分析

Application Analysis of Main and Auxiliary Separation Road in Narrow Road Dense Network Mode

为减少"窄路密网"路网模式中,主干路中长距离交通与短距离交通干扰严重导致道路通行能力下降、出入口存在安全隐患等问题,研究通过主辅分离断面对中长距离交通和沿线短距离交通进行分离的交通组织方案。通过对主辅分离断面中交叉口交通组织、主→辅转换交通、辅→主转换交通3类主要交通需求的功能进行分析,结合路网结构合理地进行交通布置。以赣州市创业路为例,验证该交通组织模式的合理性以及采用主辅分离断面后对交通的改善情况。

In order to reduce the interference of long-distance traffic and short-distance traffic on trunk road in"narrow road dense network"road network mode,the traffic capacity of the road is reduced,and there are safety hazards at the entrance and exit.The traffic organization scheme of separating the medium and long distance traffic from the short distance traffic along the line through the main and auxiliary separation section is studied.Through the analysis of the functions of the traffic organization of the intersection,the main to auxiliary transfer traffic,and the auxiliary to main transfer traffic in the main and auxiliary separation section,the traffic layout is reasonably carried out in combination with the road network structure.Taking Chuangye road in Ganzhou as an example,the rationality of the improved traffic organization mode is verified.
