摘　　要：智能网联技术的不断发展为实现公交信号优先提供了技术支持,也将助力智能网联公交向“精准公交”“安全公交”方向发展。本文从不同相位间的冲突博弈关系出发,构建智能网联环境下基于斗鸡博弈的公交信号优先引导策略。首先,利用斗鸡博弈,分析以公交优先相位与非优先相位作为博弈双方的博弈行为,建立以加权延误为收益矩阵的博弈模型;其次,考虑优先公交车的准时性、最小绿灯时长限制、优先相位及非优先相位延误等因素,结合建立的博弈模型,采取主动优先与车速引导相结合的方法,提出智能网联环境下公交优先引导策略及优化流程;最后,利用SUMO(Simulation of Urban Mobility)和采集的交叉口数据对提出的优先引导策略进行仿真。结果表明:与初始配时相比,本文提出的公交信号优先策略可有效提高公交优先相位的通行效益,减少对非优先相位的负面影响;50%渗透率条件下,对比未实施策略,20%的优先公交车准点情况优化显著,平均排队长度、平均停车次数、延误等通行效益指标至少降低33.27%,油耗及CO2排放至少降低12.20%;非优先相位各指标的劣化程度均低于8%。The ongoing development of intelligent connected technology provides crucial support for achieving transit signal priority(TSP)and assisting the development of the intelligent connected public transit towards"precision public transit"and"safe public transit".This paper starts from the conflict game relationship between different phases,and constructs a TSP guiding strategy based on chicken game in the intelligent connected environment.Firstly,the chicken game theory is used to analyze the game behavior of priority and non-priority phases of public transit,establishing a game model with weighted delay as the benefit matrix.Then,adopting the active priority and speed guidance,a TSP guiding strategy and optimization process based on the proposed game model is proposed by considering factors such as punctuality,limitation of minimum green time,priority and non-priority phase delay of priority transit.Finally,to validate the strategy,a case study is conducted using an actual intersection in Beijing,employing SUMO for simulation.The results show that the TSP guiding strategy can effectively improve the traffic efficiency of priority phases and reduce the negative impact on non-priority phases compared to the initial timing;under the condition of 50%penetration rate,compared to the implementation of strategy,20%of priority buses have been optimized significantly for punctuality,and the traffic efficiency indicators such as average queue length,average parking times and delay are reduced by at least 33.27%.Additionally,fuel consumption and CO2 emissions are reduced by at least 12.20%,and the negative influence of non-priority phase indicators is less than 8%.
