Modelling route choice behaviours are essential in traffic operation and transportation planning. Many studies have focused on route choice behaviour using the stochastic model, and they have tried to construct the heterogeneous route choice model with various types of data. This study aims to develop the route choice model incorporating travellers’ heterogeneity according to the stochastic route choice set. The model is evaluated from the empirical travel data based on a radio frequency identification device (RFID) called dedicated short-range communication (DSRC). The reliability level is defined to explore the travellers’ heterogeneity in the choice set generation model. The heterogeneous K-reliable shortest path- (HKRSP-) based route choice model is established to incorporate travellers’ heterogeneity in route choice behaviour. The model parameters are estimated for the mixed path-size correction logit (MPSCL) model, considering the overlapping paths and the heterogeneous behaviour in the route choice model. The different behaviours concerning the chosen routes are analysed to interpret the route choice behaviour from revealed preference data by comparing the different coefficients’ magnitude. There are model validation processes to confirm the prediction accuracy according to travel distance. This study discusses the policy implication to introduce the traveller specified route travel guidance system.

探索适应随机选择集生成的路线选择行为

建模路线选择行为对于交通运营和交通规划至关重要。许多研究都集中在使用随机模型的路径选择行为上,并且他们试图用各种类型的数据构造异构路径选择模型。这项研究的目的是根据随机的路线选择集建立结合旅行者异质性的路线选择模型。该模型是基于称为专用短程通信(DSRC)的射频识别设备(RFID)从经验旅行数据中评估的。定义可靠性级别是为了探索旅行者在选择集生成模型中的异质性。异构K-可靠的最短路径-(HK建立了基于RSP-)的路线选择模型,以将旅行者的异质性纳入路线选择行为中。考虑到路径选择模型中的重叠路径和异构行为,为混合路径大小校正logit(MPSCL)模型估计了模型参数。通过比较不同系数的大小,分析了与所选路线有关的不同行为,以根据揭示的偏好数据来解释路线选择行为。有一些模型验证过程可以根据行进距离来确认预测准确性。本研究讨论了引入旅行者指定路线旅行引导系统的政策含义。
