Abstract

This paper presents an analytical framework for evaluating the performance of dedicated bus lanes. It assumes that under a designated travel demand, the traffic volume on a corridor changes with the modal shifts. The modal shift affects the operations of both bus traffic and car traffic and eventually, an equilibrium bus share ratio that maximizes the performance of the corridor will be reached. Microsimulation modelling is employed to assess the traffic operations under various demand levels and bus share ratios. The results show that converting a general lane into a bus lane significantly reduces bus delay. For car traffic, the overall trend is that delay increases after converting a general lane to a bus lane. In addition, delay decreases with the increase of bus share ratio. Nevertheless, when bus share ratio reaches 0.6 (demand less than 10,000 passengers per hour, pph; or 0.8 when demand increases up to 14,000 pph), there is no significant difference in delay between the two scenarios. The identified bus share ratios have the potential to direct the development of bus lane warrants. Finally, this research recommends that the Transportation Demand Management (TDM) strategies shall be developed to stimulate the modal shifts towards the identified optimal bus share ratio.

将普通车道改为公交专用道的模态转换效应建模

本文提出了一个评价公交专用道性能的分析框架。假设在一定的出行需求下，走廊上的交通量随交通模式的变化而变化。模式转换同时影响公交交通和小汽车交通的运行，最终达到一个平衡的公交份额比，使走廊的性能最大化。采用微观仿真模型对不同需求水平和公交共享比例下的交通运行进行了评估。结果表明，将普通车道转换为公交车道可显著降低公交延迟。对于汽车交通，总体趋势是将普通车道转换为公共汽车车道后延迟增加。延迟随母线共享比的增大而减小。然而，当公交车份额比达到0.6时(需求低于每小时10,000人次，pph;或者当需求增加到14,000 pph时为0.8)，两种情况之间的延迟没有显着差异。确定的巴士共用比率有可能指导巴士车道权证的发展。最后，本研究建议制定交通需求管理(TDM)策略，以刺激模式向确定的最优公交份额比例转变。
