【摘要】 专用道公交信号优先能显著提高公交系统运行效率,本研究针对单个交叉口主动信号优先策略可能失效的问题,以干线交叉口群为对象,建立专用道公交信号优先协调控制模型,在保证社会车辆协调控制效果不受影响的前提下,协调各个交叉口的公交主动优先策略触发与否,提高公交车辆运行效率的同时,减少主动优先策略被触发的次数,避免不必要的时空资源浪费。专用道公交信号优先协调控制模型为混合整数线性规划模型,利用分支定界法求解。以延安路常德路-茂名北路路段为例,对模型进行验证分析,结果表明,专用道公交信号优先协调控制模型使得主动优先策略被触发的次数降低了33%,并能减少公交车辆的延误和停车。更多还原

【Abstract】 Traffic signal priority can significantly improve the efficiency of public transport system. Focused on the problem that the active priority strategies of a single intersection may fail, this study established coordination model of transit priority strategies based on the arterial intersection group. Coordinate the transit priority strategies to trigger or not, under the premise of ensuring the coordination effect of social vehicles is not affected. Reduce the number of active priority strategy is triggered to avoid unnecessary waste of time and space resources, and improve the efficiency of public transport vehicles at the same time. Coordination model of transit priority strategies is formulated as a mixed-integer linear program, which can be solved by the standard branch-and-bound technique. Taking the Changde Road-Maoming North Road section of Yan’an Road as an example, the model is validated and analyzed. Results have demonstrated that the model reduces the number of transit priority strategies triggered by 33% and reduces delays and number of stops on transit vehicles.更多还原
