【摘要】：为满足当前高速公路各类型车辆加油需求,解决各类型车辆等待加油时间过长等问题。选取主线驶入量、不同车型加油率及不同车型加油周转率等参数,基于排队论建立了加油区排队系统模型,确定了其系统在平稳分布下加油车辆平均逗留时间、服务强度及平均排队加油车辆数均值之间的关系;考虑排队车辆容忍等待时间少于加油车辆平均逗留时间的条件约束,通过对排队车辆调查,进而得出加油区合理用地规模。以大广高速衡大段威县服务区为例,计算得出加油区的用地量。结果表明:考虑不同车型加油率的加油区用地规模计算能有效协调并减少各类车型等待加油时间。
[Abstract]:In order to meet the current vehicle refueling demand of various types of freeway and solve the problem of long waiting time for each type of vehicle, select the main line input volume, different vehicle type refueling rate and different vehicle type refueling turnover rate and other parameters. Based on the queuing theory, the queuing system model of refueling area is established, and the relationship among the average sojourn time, service intensity and the average number of queuing vehicles under the steady distribution of the system is determined. Considering the constraint that the waiting time of queuing vehicles is less than the average stay time of refueling vehicles, the reasonable land scale of refueling area is obtained through the investigation of queuing vehicles, taking Weixian service area as an example. The results show that the calculation of the scale of the refueling area considering different vehicle type refueling rate can effectively coordinate and reduce the waiting time for all kinds of vehicles.
