【摘要】：随着交通需求的增加,目前城市路网经常呈现出高度过饱和的交通状态,在交叉口处排队等待通行的车辆不断累积,当车辆排队长度逐渐增加至超过路段长度时就会出现排队溢出现象,排队溢出的车辆会阻碍交叉口其他方向车辆的运行,严重时会导致交叉口“死锁”,造成交通拥堵。为了解决由此引发的交通拥堵,提高路网的通行效率,预防交叉口排队溢出措施的研究显得尤为重要。针对排队溢出现象频繁发生引发的严重交通拥挤问题,本文对预防交叉口排队溢出的交通信号控制方法进行了研究。通过交通调查和在对排队溢出现象及其影响进行简要描述之后,对排队溢出进行了分类,并分析出交叉口排队溢出形成的原因。综合考虑通过上游交叉口的车辆到达下游交叉口时,下游交叉口的信号灯状态及交通流排队情况,应用停车波和起动波的传播机理,建立了相邻信号交叉口之间最大排队长度计算模型,并利用实际调查数据通过计算跟踪误差验证了该模型计算结果的可靠性。在此基础上,根据路段容量的定义建立了基于排队长度的剩余容量预测模型,为后续优化控制模型的研究奠定基础。随后提出了基于交叉口出口车道剩余交通容量限制的交通信号控制策略,借鉴公交优先的信号控制思想,通过压缩绿灯时间、延长绿灯时间、跳跃相位等方法,建立了基于出口车道剩余容量限制的交通信号优化控制模型,并对该优化控制模型的运行过程及结果进行仿真模拟,仿真结果表明,该优化控制模型的实施能够有效地预防交叉口排队溢出的发生,提高交叉口的通行效率。最后从工程措施、技术措施、交通管理措施三方面提出了一些预防交叉口排队溢出的对策。
[Abstract]:With the increase of traffic demand, the urban road network often shows a highly saturated traffic state, the vehicles waiting in line at the intersection continue to accumulate, when the queue length gradually increases to exceed the length of the road section, there will be queue overflow phenomenon. The queue overflow vehicle will hinder the operation of vehicles in other directions of the intersection, and in serious cases, it will lead to "deadlock" at the intersection, resulting in traffic congestion. In order to solve the traffic congestion and improve the traffic efficiency of the road network, it is particularly important to study the measures to prevent the queue overflow at intersections. In order to solve the problem of serious traffic congestion caused by the frequent occurrence of queue overflow, the traffic signal control method to prevent queue overflow at intersections is studied in this paper. Through traffic investigation and a brief description of queuing overflow phenomenon and its influence, the queuing overflow is classified, and the causes of queue overflow at intersections are analyzed. Considering the signal light state and traffic flow queuing of downstream intersections when vehicles arrive at downstream intersections through upstream intersections, a calculation model of maximum queue length between adjacent signalized intersections is established by using the propagation mechanism of parking wave and starting wave, and the reliability of the calculation results of the model is verified by the actual investigation data through the calculation and tracking error. On this basis, according to the definition of road section capacity, a residual capacity prediction model based on queue length is established, which lays a foundation for the subsequent research of optimal control model. Then the traffic signal control strategy based on the residual traffic capacity limitation of intersection exit lane is put forward, and the traffic signal optimization control model based on the residual capacity limit of exit lane is established by reducing the green light time, prolonging the green light time and jumping phase by using the signal control idea of bus priority for reference, and the operation process and results of the optimal control model are simulated. The implementation of the optimal control model can effectively prevent the occurrence of queue overflow at intersections and improve the traffic efficiency of intersections. Finally, some countermeasures to prevent queue overflow at intersections are put forward from three aspects: engineering measures, technical measures and traffic management measures.
