小区开放后车辆通行能力研究

针对开放小区对小区开放后道路通行能力及路口通行能力的影响,本文构建了车辆通行的数学模型,用以研究小区开放对周边道路通行的影响。通过将周围道路通行能力分为道路通行能力与路口通行能力,建立以流量、平均通行时间、车辆密度为指标的道路通行模型和路口通行模型。然后,根据M/G/1排队模型构建交叉入口个数与安全性之间的模型。最后,构建车辆可达度与便捷性的模型,通过研究小区开放前后各指标的差异反映小区开放对周边道路通行影响。

aiming at the influence of the open community on the road traffic capacity and the traffic capacity of the intersection after the opening of the community,this paper constructs a mathematical model of vehicle traffic to study the influence of the opening of the community on the surrounding road traffic.By dividing the surrounding road capacity into road capacity and intersection capacity,the paper establishes the road capacity model and intersection capacity based on traffic flow,average passage time and vehicle density.Then,according to the M/G/1 queuing model,the model between the number of crossings and security was constructed.Finally,the model of vehicle accessibility and convenience is constructed to reflect the influence of the opening of the community on the surrounding roads by studying the difference of each index before and after the opening of the community.
