基于随机过程的服务区停车位数计算方法

基于交通流理论,以随机过程分析为手段,从车辆和道路使用者对各种服务的需求周期性出发,讨论了不同类型服务高峰小时的成因,从机制上解释了服务区高峰小时停留率的形成模式,得出了服务区停车位数与服务区路网布局之间的定量关系,提供了实际路网的服务区停车位数计算方法,并通过算例与日本规范的计算方法进行比较。结果表明:提出的计算方法体现了服务设施间距等因素对服务区停车位数的影响,对服务区高峰小时停留率以及停车位规模计算方法进行了改进;计算结果与日本规范中的计算结果一致。

Stochastic Process-based Calculating Method of Amount of Parking Space of Service Area

Using the stochastic process analysis and starting with the analysis of the periodicity of requirement of each kind of service that was needed by vehicles and passengers on expressway,the causes of peak hour of different kinds of services on the basis of traffic flow theory were consulted,a systematic explanation of the constitutional mode of the pause rate in peak hour of service area was put forward,the quantitative relation between the amount of parking space and distribution of service facilities in roa...
