【摘要】：随着我国市场经济的飞速发展,城市机动车保有量不断增加,为了适应交通需求的增长,缓解城市拥堵问题,各类交通基础设施的建设都得到大力的推进与发展。而交通基础设施在建设的过程中往往需要占用道路资源,特别当施工占用道路资源较多、施工位置处于城市交通要道时,如不对区域路网进行及时有效的交通组织,就极易造成大面积的交通拥堵甚至瘫痪。本文以主干道占道施工影响区域路网为研究对象,以主干道拥堵程度降低,支路利用率提高为交通组织优化目标来探究路网禁限管理方式的合理性。本文首先阐述占道施工控制区的组成,分析施工区域影响路网内人员、车辆、道路与安全方面的交通特性。再根据Greenshields模型与Greenberg模型标定BPR函数参数,构造了更适用于施工区域影响路网交通分配与OD反推的路阻函数。对于OD反推算法,本文采用广义最小二乘模型与增量加载分配法结合的双层规划模型,并用遗传算法求解,从而根据路段交通量与先验OD矩阵确定路网分配的初始OD矩阵。同时本文将路网OD矩阵分配得到的路段流量作为评价路网交通状态的重要依据,并将不同的禁限管理方法特别是转向禁限通过权矩阵、通行能力矩阵以及路阻函数的改变与变形来使得管理方法在静态分配中得以体现。并在算例路网中对禁限管理后的路网OD矩阵进行重分配来判断路网交通组织的优化效果,从而给出禁限管理的适用性条件。
[Abstract]:With the rapid development of market economy in China, the number of urban motor vehicles has been increasing. In order to adapt to the growth of traffic demand and alleviate the problem of urban congestion, the construction of all kinds of traffic infrastructure has been vigorously promoted and developed. The traffic infrastructure often needs to occupy the road resources in the process of construction, especially when the construction takes up more road resources, the construction location is in the urban transportation roads, such as do not carry on the timely and effective traffic organization to the regional road network. It is easy to cause a large area of traffic congestion or even paralysis. In this paper, the main road construction affecting the regional road network as the research object, with the main road congestion degree reduced, the increase in the utilization of branch roads as the goal of traffic organization optimization to explore the road network ban management mode rationality. In this paper, the composition of the construction control area of the Occupy Road is first expounded, and the traffic characteristics of the construction area affecting the people, vehicles, roads and safety in the road network are analyzed. According to the Greenshields model and Greenberg model, the parameters of BPR function are calibrated, and the road resistance function which is more suitable for the road network assignment and OD backstepping in construction area is constructed. In this paper, the generalized least square model and incremental load allocation method are used to solve the inverse OD method, and the genetic algorithm is used to solve the problem. The initial OD matrix of road network allocation is determined according to the traffic volume and the prior OD matrix. At the same time, this paper takes the road flow from OD matrix distribution as an important basis to evaluate the road network traffic status, and uses different forbidden management methods, especially the weight matrix. The change and deformation of the capacity matrix and the road resistance function make the management method reflect in the static distribution. The OD matrix of road network after ban management is redistributed to judge the optimization effect of traffic organization in road network, and the applicable condition of forbidden limit management is given.
