【摘要】：随着汽车保有量的不断增加和新型城镇化战略的推进,道路交通拥堵现象成为困扰城市发展的重要桎梏,城市中交通拥堵往往发生在道路瓶颈处。交叉口作为城市交通瓶颈,因为信号设置而引起车辆排队通行,这种排队现象往往延伸至交叉口进口道上。跟驰和换道作为车辆行驶的两种常见行为,在交叉口车辆排队通行的情况下,换道行为便成为插队行为,车辆的插队将使后车行驶速度和轨迹发生变化并随交通流向上下游传播,为道路交通带来更多不稳定因素,使道路交通安全受到影响。深入研究车辆插队行为,从插队行为的全过程对插队行为进行分析,对减少插队行为的负面影响,改善城市交通环境具有重要意义。论文将车辆的插队行为划分为插队决策、插队实施和插队影响三个阶段,应用博弈论、元胞自动机、交通流理论等科学理论对三个阶段进行了研究和分析。首先,针对车辆插队决策,考虑到插队车辆和被插队车辆间动态的持续博弈,应用演化博弈论建立相关模型并通过道路交通实例进行验证;其次,针对车辆插队实施,根据现实中插队换道的不同类型,结合演化博弈论研究成果,确定元胞自动机的换道规则,建立了还原车辆插队过程的元胞自动机模型,并利用计算机软件进行仿真验证;最后,针对车辆插队影响,在微观层面分析了其他车辆行驶受到的影响,在宏观层面上分析了交通流运行在插队成功和插队失败两种情况下受到的影响。另外,结合论文研究过程中的启发和思考,针对交叉口排队情况下车辆插队对道路交通安全产生的影响,提出了较为具体的改善建议。
[Abstract]:With the increasing number of cars and the promotion of the new urbanization strategy, the phenomenon of road traffic congestion has become an important shackle to the development of cities. Traffic congestion often occurs at the neck of the road in the city. As a bottleneck of urban traffic, intersections lead to vehicle queuing due to signal setting, which often extends to the intersection entrance roads. As two common behaviors of vehicles, car-following and change-over become queue-cutting behavior when vehicles are queued at intersections. The speed and trajectory of the rear vehicle will change and propagate along with the traffic flow up and down, which will bring more unstable factors to the road traffic and affect the road traffic safety. In-depth study of vehicle queue-cutting behavior, from the whole process of queue-cutting behavior analysis, to reduce the negative impact of queue-cutting behavior, improve the urban traffic environment is of great significance. In this paper, the vehicle queue-jumping behavior is divided into three stages: decision-making, implementation and impact. The research and analysis of the three stages are carried out by using the game theory, cellular automata, traffic flow theory and other scientific theories. Firstly, in view of the decision-making of vehicle cut-in, taking into account the dynamic continuous game between the queue-jumping vehicle and the cut-in vehicle, the evolutionary game theory is used to establish the relevant model and verify it by the road traffic example. Secondly, aiming at the implementation of vehicle queue-jumping, according to the different types of route-cutting in reality, combining with the research results of evolutionary game theory, the lane-changing rules of cellular automata are determined, and the cellular automata model of reducing the process of vehicle queue-jumping is established. And use the computer software to carry on the simulation verification; Finally, aiming at the effect of vehicle queue-cutting, the paper analyzes the influence of other vehicles on the micro-level, and on the macro-level, analyzes the influence of traffic flow operation on the success of queue-jumping and the failure of queue-jumping. In addition, combined with the inspiration and thinking in the research process of the paper, this paper puts forward some concrete suggestions to improve the road traffic safety caused by vehicle insertion in the condition of intersections queuing in the light of the influence on road traffic safety under the condition of intersections queuing.
