摘要

间歇性公交专用道可以缓解公交优先与普通车辆对道路资源的迫切需求之间的矛盾。然而,现有的IBL策略很少关注交叉口动态公交专用道的设置方法,这导致在交通拥堵环境下,交叉口公交车仍然严重延误。为了解决这个问题,本研究探索了一种新的方法,即设置交叉口的间歇公交引道(IBA),以实现交叉口的车道共享和公交优先权。特别是,为了充分合理地分配交叉口公交专用道的空闲时间,提出了一种具有交叉口信号协调模型的时间片划分策略。此外,考虑到交叉口普通车辆的变道需求,对IBA车道系统的参数进行了建模和优化。为了测试和验证该方法的可行性,通过微观交通模拟进行了对比实验。结果表明,所提出的IBA设置方法可以有效地解决交叉口公交优先故障的问题。它可以保持车辆在交叉口路段行驶的连续性,更好地发挥了动态公交专用道的运营效益。

Setting the Intermittent Bus Approach of Intersections: A Novel Lane Multiplexing-Based Method with an Intersection Signal Coordination Model
Intermittent bus lanes (IBLs) can alleviate the contradiction between bus priority and the urgent demand of general vehicles for road resources. However, existing IBL strategies seldom pay attention to the setting method of the dynamic bus lanes at intersections, which leads to the still serious delay of buses at intersections in the traffic congestion environment. To tackle this issue, this research explores a novel method of setting the intermittent bus approach (IBA) of intersections for lane sharing and bus priority at intersections. In particular, a time slice division strategy with an intersection signal coordination model is developed to fully and reasonably allocate the idle time of bus lanes at intersections. Besides, considering the lane-changing demands of general vehicles at intersections, the parameters of the IBA lane system are modeled and optimized. For testing and verifying the feasibility of the proposed method, comparative experiments are conducted through microscopic traffic simulation. Results show that the proposed IBA setting method can effectively solve the problem of bus priority failure at intersections. It can maintain the continuity of vehicle running on intersection sections, which better exerts the operational benefits of dynamic bus lanes.

期刊介绍: Applied Sciences (ISSN 2076-3417) provides an advanced forum on all aspects of applied natural sciences. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
