城市道路施工区交通延误建模与仿真

随着城市的快速发展,为了提高道路通行能力,许多道路必须扩建,而施工区广泛存在于路段和交叉口区域,城市道路施工区将改变车道的宽度,对车辆的正常行驶产生一定的影响,导致大量排队和交通延误.针对城市路段施工区的交通流和交通延误进行了仿真,研究施工区域环境中不同因素对车辆延误的影响、机动车和非机动车到达率,分析了受施工区影响的入口交通延误的特征,施工区的尺寸与位置等因素对路段施工区交通延误的影响,提出了基于社会力模型的城市路段施工区交通延误分析方法,并考虑了路段施工区长度、施工区宽度、大型车比例将对路段施工区的交通延误和平均通行速度产生显著影响.模拟结果表明,本文建立的基于社会力模型的施工区交通延误计算方法具有良好的适用性.基于分析结果可制定合适的交通管理措施,减少路段施工区的交通拥堵降低延误和事故率.

Modeling and Simulation Analysis of Traffic Delayin Urban Work Zone

With the rapid development of the city, to improve the road capacity, many roads must be expanded, so the work zone widely exists in the road sections and intersections. The work zone on the urban road will change the road width, which will have a certain impact on the normal driving of vehicles, resulting in a large number of queues and traffic delays. This paper, simulates the traffic flow and traffic delays in the work zone of urban road sections, studies the impact of different factors in the work zone environment on vehicle delays, the arrival rate of motor vehicles and non-motor vehicles, and analyzes the characteristics of the entrance traffic delays affected by the work zone, The size and location of the work zone and other factors affect the traffic delay in the work zone of the road section. The analysis method of traffic delay in the work zone of the urban road section based on the social force model is proposed, and the length of the work zone, the width of the work zone, and the proportion of large vehicles It has a significant impact on traffic delays and average traffic speeds in the work zone of the road section. The simulation results show that the calculation method of traffic delay in the work zone based on the social force model established in this paper has good applicability. Based on the analysis results, appropriate traffic management measures can be formulated to reduce traffic congestion in the work zone of the road section and reduce the delay and accident rate.
