摘要:
为了提高现代有轨电车运行效率，在道路平交路口处实施信号优先是应用最为普遍的方法。对现代有轨电车通过交叉口时形成的离散交通流，提出了其特定的延误公式，构建了以人总延误的减小量为参考指标的主动优先效益模型，并通过判断效益模型的结果是否为正来决定能否采取主动优先控制策略。以武汉市东湖高新区的现代有轨电车T1线为例，对模型进行仿真分析与验证。结果表明，与常规信号控制策略相比，主动信号优先具备更好的控制效果；与绿灯提前控制策略相比，绿灯延长策略的效果更加显著。
Abstracts:
Signal priority at intersection is the most commonly adopted method to improve the efficiency of modern trams. Aiming at the discrete traffic flow when the modern tram passing through intersections, a specific delay formula is put forward and an active priority benefit model is built based on the reference index of total delay reduction, and the adoption of active priority control strategy is decided according to the results of the model performance. Taking the modern tram T1 Line in the East Lake High-tech Zone of Wuhan City as a reference, the model is simulated and verified. The result shows that the active signal priority has better control effect compared with conventional signal control strategies, but is less effective compared with the green light advance control strategy.
