【摘要】 为探究高速公路差异化收费对货车驾驶员出行行为的影响，选取付费方式、运输时间紧急性、选择重视因素和情境选择行为4个因素作为外显变量，在提高高峰期收费费率的场景下，构建货车驾驶员群体细分的潜在类别模型。基于重庆市584份高速公路货车出行行为问卷调查数据，对其进行类别划分，并对比分析了各类货车驾驶员的出行选择偏好。研究表明：(1)货车驾驶员群体可划分为灵活型、无奈型和忠诚型3类，且货物类型和运输成本对驾驶员的类别划分有显著影响；(2)随着高速公路月通行次数的减少，忠诚型选择重视里程的概率呈线性增长趋势，且会显著影响灵活型选择改变出行路径的概率；(3)当运输成本提高时，灵活型出行选择会更加看重通行费用的高低，而忠诚型则注重高速公路良好的行车体验；(4)无奈型迫于货物的运输时间要求，提高收费场景下的行为特征差异较小。因此，针对不同类型货车驾驶员群体应制定差异化的收费定价策略，以避免高速公路货运用户流失。更多还原

【Abstract】 To investigate the impact of expressway differentiated charging on the travel behavior of truck drivers, the payment mode, transportation time urgency, choice factor, and situational choice behavior were selected as explicit variables. A latent class model of truck driver groups was established under the scenario of increasing charges during peak periods. Based on 584 questionnaire survey responses on expressway truck travel behavior in Chongqing, the drivers were classified and the travel preferences of various truck drivers were compared and analyzed. The results show that:(1) the truck drivers can be classified into three categories: flexible drivers, helpless drivers, and loyal drivers, and cargo type and transportation cost have a significant impact on the classification;(2)as the monthly usage frequency of expressway decreases, the probability of loyal drivers choosing to value mileage increases linearly, and it also will significantly affect the probability of flexible drivers changing their travel routes;(3)when transportation costs increase, flexible drivers tend to place greater emphasis on the toll, while loyal drivers focus on having a good driving experience on the expressway;(4)behavioral characteristics of helpless drivers under the increased charges situation have slight differences due to the transportation time requirements of cargo. Therefore, differentiated charging strategies should be formulated for different categories of truck drivers to avoid the loss of expressway freight users.更多还原
