提出了一种小汽车和公交车双模式可降解路网中公交专用道的评价方法。在考虑路段随机退化的情况下，分析了两种交通方式下有无EBL的路段行程时间。此外，路线一般行程成本的不确定性，制定了两种模式的路段行程时间的不确定性和不确定性，在一个公共汽车站的等待时间和车辆拥挤成本的公共汽车模式。公交车等待时间的不确定性被认为是有关的退化的前链接的公交线路。提出了一个考虑出行者风险厌恶行为的双模态用户均衡模型，用于评价EBL。最后，通过两个算例说明了道路退化水平、出行者风险厌恶水平和前路段与公交车等待时间不确定性的相关水平对有无EBL的用户均衡模型结果的影响，以及道路退化水平对EBL最优设置方案的影响。此外，本文还分析了EBL设置的一个悖论，即增加一条公交专用道可能会减少公交份额。(C)2015爱思唯尔有限公司版权所有。
In this paper, we proposed an evaluation method of exclusive bus lanes (EBLs) in a bimodal degradable road network with car and bus transit modes. Link travel time with and without EBLs for two modes is analyzed with link stochastic degradation. Furthermore, route general travel costs are formulated with the uncertainty of link travel time for both modes and the uncertainty of waiting time at a bus stop and in-vehicle congestion costs for the bus mode. The uncertainty of bus waiting time is considered to be relevant to the degradation of the front links of the bus line. A bi-modal user equilibrium model incorporating travelers' risk adverse behavior is proposed for evaluating EBLs. Finally, two numerical examples are used to illustrate how the road degradation level, travelers' risk aversion level and the front link's correlation level with the uncertainty of the bus waiting time affect the results of the user equilibrium model with and without EBLs and how the road degradation level affects the optimal EBLs setting scheme. A paradox of EBLs setting is also illustrated where adding one exclusive bus lane may decrease share of bus. (C) 2015 Elsevier Ltd. All rights reserved.
