Abstract: The influence of service area’s space information, service level, and freeway topographic conditions on service area’s land was considered in the distribution function of vehicle continuous driving time, and the calculation method of service area’s drivinginto rate based on vehicle continuous driving time was put forward. Considering the composition of main line’s traffic volume and the service demand characteristics of different types of vehicles, the service traffic volume and the passenger flow volume of service areas were calculated; at the same time, the land of parking lots, public toilets, acceleration lane and deceleration lane, restaurants and other facilities were calculated respectively, and then the calculation model of service area’s land was determined. Finally, referring to OD survey data of Hengshui—Daming section on DaqingGuangzhou Expressway in the stage of engineering feasibility study, the calculation of the drivinginto rate and the reasonable land of each service facility in each service area along the expressway was completed, and the reasonable land of each service area was obtained.

Key words: traffic and transportation engineering, service area, drivinginto rate, continuous driving time

摘要： 将服务区间距信息、服务水平、高速公路所处地形条件等因素对服务区用地量的影响引入车辆连续行驶时间分布函数中，提出了基于连续行驶时间的服务区驶入率计算方法。考虑主线交通量的交通组成、不同车型的服务需求特性，计算服务区的服务交通量和服务客流量，并对停车场、公共厕所、加减速车道、餐厅等设施的用地面积分别进行计算，从而确定服务区的用地量计算模型。最后借用大广高速衡大段工可阶段OD调查数据，完成了对其沿线各服务区驶入率和各服务设施的合理用地量的计算，得到了各服务区的合理用地量。
