小区开放对周边道路通行的影响

The Impact of Community Opening on the Surrounding Roads

摘要: 本文通过探究开放小区的内部道路对于周边道路不同的分流能力，进而研究在通行高峰时段，小区开放后，对周边道路通行情况的不同影响。首先以层次分析法建立一个三层的完整评价体系来评价小区开放对周边道路影响。其次，基于无信号交叉口的理论通行能力模型，解决开放小区后形成的支路分流能力问题，并明确支路的分流能力模型，以此来研究开放小区对周边道路通行的影响。接着，会对支路通行能力和周边道路通行量分四种情况进行运算。最后通过评价指标综合考虑小区开放前后对周边道路的影响，并从不同小区的不同道路结构出发，结合周边道路的交通情况给出建议。

Abstract: This paper explores the capacity of branch roads under different trunk roads to discuss the impact of different road conditions around the community during peak traffic hours, and studies the dif-ferent impacts of community opening on the surrounding roads. Firstly, a three-level complete evaluation system is established by analytic hierarchy process to evaluate the impact of community opening on surrounding roads. Secondly, based on the theoretical capacity model of the un-signalized intersection, the problem of the branch diversion capacity formed after the open cell is solved, and the shunt capacity model of the branch is determined to study the influence of the community opening on the surrounding road traffic. And the calculation of the branch capacity and the surrounding road traffic are divided into four cases. Finally, this paper comprehensively considers the impact on the surrounding roads before and after the community opening with the evaluation indicators and combines with the traffic conditions of the surrounding roads to give recommendations from the different road structures of different communities.
