摘要: 公交车内拥挤成本是公交出行成本的重要组成部分,针对其非市场商品特性,引入条件价值法,以效用最大化为目标建立公交出行选择效用函数,并利用支付意愿法推导出以时间价值为自变量的拥挤成本测算模型。在此基础上,分析时间价值与车内拥挤程度的内在关系,指出现有时间价值-拥挤程度模型存在的问题并对其进行改进。最后根据杭州市拥挤度支付意愿问卷调查数据建立二元Probit模型标定相关参数,量化公交出行拥挤成本。结果表明:公交车内拥挤成本随着拥挤程度的增加而非线性增加,当乘载率大于2.0时,拥挤成本占公交出行成本的1/3。

关键词: 道路工程, 条件价值法, 拥挤成本, 时间价值, 乘载率

Abstract: Contingent Valuation Method (CVM), one of the most widely used methods to estimate non-market goods, was introduced to quantify the crowding costs in bus, which is an important part of the total costs of bus trip. With the goal of utility maximization, the relationship between the crowding costs and Value of Time (VOT) was deduced from the concept of willingness to pay. To further establish the model of the crowding costs and load factors, the relationship between VOT and load factors was analyzed and improved based on the existing models. Meanwhile, in accordance with the questionnaire data in Hangzhou city, the relevant parameters were obtained using the binary Probit model. Then, the crowding costs were quantified under different crowding conditions. The results show that the crowding costs are nonlinear, when the load factor is greater than 2.0 the crowding cost is one third of the total costs of bus trip.

Key words: road engineering, contingent valuation method (CVM), crowding costs, value of time, load factor
