摘要
目前我国通常采用驶入率参数来计算公路服务设施规模,但驶入率参数值难以准确确定.本文提出一种无须驶入率参数、更加贴近实际停车需求的服务设施停车容量计算模型.该模型基于司乘人员和机动车出行途中需要经常停车休息的规律,改进四阶段预测方法中交通分配模型,根据路网中车辆的出发地、行驶路径和停车间隔来确定路网中路段停车需求量,以此来计算该路段上服务设施的停车容量.本文给出了该预测模型的计算步骤、服务设施停车位数计算公式和相关参数,并利用实测数据对模型进行了验证.最后以内蒙古自治区S308的服务设施设置为例,采用模型计算了公路服务设施停车容量.
The size of highway service area is usually calculated by the parking rate which is difficult to be deterined accurately. A forecasting model of service area parking capacity is put forward to calculate the size without parking rate but meeting the parking demand. In view of the character that traveler and motor ve- hicle stop for relaxing, the traffic assignment model of four-stage forecast method is improved to compute parking demand according to the origination place, tip path, and rest interval in the network of each trip, and then determine the parking capacity. This paper presents the calculation steps, formula of parking ca- pacity, relevant parameters. The model is validated by observed data to calculate the capacity of the service area of S308 road in the Inner Mongolia Autonomous Region.
