多元收费方式下的高速公路收费站车道数优化研究

随着货车比增加和移动支付方式的应用,依据现有《收费公路联网技术要求》计算车道数用到的交通量换算和服务时间已不符合实际,造成车道数计算不准确,易导致车道拥堵或车道资源浪费. 本文围绕车道数优化计算展开研究. 首先分析多元收费方式服务时间及其差异性,提出多元收费方式服务时间计算模型. 考虑车辆跟驰、排队等行为因素,基于 VISSIM 建立收费站通行仿真模型,以车流量、车型比等数据为输入,获取满足设计需求的车道数. 将需求车道数和实际服务时间输入排队模型计算DHV修正值. 利用多项式回归,建立实际DHV值和DHV修正值间的DHV换算模型. 根据实际服务时间和DHV修正值,获得优化车道数. 最后,以典型收费站进行实证分析,表明本文方法可实现车道数的优化计算.

Optimization of Lane Number of Highway Toll Station Based on Multiple Payments

With the increase of trucks and the application of mobile payment methods, the number of lanes is calculated according to the "Toll Road Networking Technical Requirements". The traffic volume conversion and service time are not in line with reality, and the number of lanes is not accurately calculated, resulting in congestion or waste of lane resources. This paper focuses on the calculation of the number of lanes. Firstly, this paper analyzes the difference of service time and proposes a service time calculation model of multi payments. Considering behavioral factors such as vehicle following and queuing, a toll station simulation model is established based on VISSIM. Take the traffic volume, model ratio as input to obtain the number of lanes that meet the design requirements. Enter the number of required lanes and service time into the queuing model to calculate the DHV correction value. This paper establishes a DHV conversion model between the actual DHV value and the DHV correction value. Based on the service time and DHV correction value, the number of optimized lanes is obtained from the number of lanes in the technical requirements. Finally, with the empirical analysis of the toll station, this method can achieve the optimal calculation of the number of lanes.
