研究了公交、单人驾驶和拼车三种出行方式的公交专用道在路网中的评价问题。建立了一个三式联运网络均衡模型来分析EBL在三种不同策略下的效果：(I)不使用EBL(称为策略1)；(Ii)EBL只能由公交车使用(称为策略2)；(Iii)EBL可用于公共汽车和拼车模式(称为策略3)。在综合考虑ENS设置方案和公交班次的基础上，建立了组合优化模型，对三式联运系统的性能进行了测试。数值结果表明，在单O-D对的交通走廊情况下，出行需求水平会显著影响不同政策下的系统总成本。分析了平均拼车占有率和出行方式选择参数对出行者选择行为的影响。最后，通过一个具有19条链路的三通道网络实例，说明了在不同的链路上采用不同的EBLS策略可以提高系统的效率。
This paper considers the evaluation of exclusive bus lanes (EBLs) in the road network with three travel modes: bus, solo driving, and carpooling. A tri-modal transportation network equilibrium model is developed to analyze the effects of EBLs under three different policies: (i) no EBLs (called Policy 1); (ii) EBLs can only be used by bus (called Policy 2); and (iii) EBLs can be used by both bus and carpooling modes (called Policy 3). By taking into account both Ens setting scheme and bus frequencies, a combinatorial optimization model is proposed to test the performance of the tri-modal transportation system. In a traffic corridor case with single O-D pair, numerical results show that travel demand levels will remarkably influence the total system costs under different policies. The effects of average carpooling occupancy and mode choice parameters on travelers' choice behavior are analyzed. Finally, a tri-modal network with nineteen links is used to illustrate that the system could be more efficient when different EBLs policies are adopted on different links.
