在总结国内外对车辆行为时间价值研究的基础上,提出了一种车辆行为时间价值计算方法———车型分类法。首先,对公路网上的车辆,按照其经济属性、社会属性和车型3个标准进行组合分类。然后,构建虚拟路网,并对各类型车辆的路径选择行为进行选择性偏好问卷调查,通过调查得到每类车辆选择各条路线的比例。最后,利用路线选择比例,通过建立交通方式选择数学模型,反算车辆广义费用,进而确定车辆的行为时间价值。车辆行为时间价值的计算对于确定车辆的广义费用,分析车辆路径选择行为具有重要意义,是交通流分配的关键环节,并且是交通流分析与预测的前提。
On the basis of summarizing the research on the time value of vehicle behavior both at home and abroad, this paper proposes a vehicle behavior time value calculation method --- vehicle classification. First of all, on the road network of vehicles, according to their economic attributes, social attributes and models of three combinations of classification. Then, the virtual road network is constructed, and the selective preference survey is conducted on the route selection behaviors of all kinds of vehicles. The proportion of each route selected by each type of vehicle is obtained through investigation. Finally, by using the proportion of route selection, the mathematical model of transportation selection is established to inverse the generalized cost of the vehicle and to determine the value of the vehicle’s behavior time. The calculation of vehicle behavior time value is of great significance to determine the vehicle’s generalized cost and to analyze the vehicle routing behavior. It is a key link of traffic flow distribution and a precondition of traffic flow analysis and prediction.
