【摘要】：隨著我國市場經(jīng)濟(jì)的飛速發(fā)展,城市機(jī)動(dòng)車保有量不斷增加,為了適應(yīng)交通需求的增長,緩解城市擁堵問題,各類交通基礎(chǔ)設(shè)施的建設(shè)都得到大力的推進(jìn)與發(fā)展。而交通基礎(chǔ)設(shè)施在建設(shè)的過程中往往需要占用道路資源,特別當(dāng)施工占用道路資源較多、施工位置處于城市交通要道時(shí),如不對區(qū)域路網(wǎng)進(jìn)行及時(shí)有效的交通組織,就極易造成大面積的交通擁堵甚至癱瘓。本文以主干道占道施工影響區(qū)域路網(wǎng)為研究對象,以主干道擁堵程度降低,支路利用率提高為交通組織優(yōu)化目標(biāo)來探究路網(wǎng)禁限管理方式的合理性。本文首先闡述占道施工控制區(qū)的組成,分析施工區(qū)域影響路網(wǎng)內(nèi)人員、車輛、道路與安全方面的交通特性。再根據(jù)Greenshields模型與Greenberg模型標(biāo)定BPR函數(shù)參數(shù),構(gòu)造了更適用于施工區(qū)域影響路網(wǎng)交通分配與OD反推的路阻函數(shù)。對于OD反推算法,本文采用廣義最小二乘模型與增量加載分配法結(jié)合的雙層規(guī)劃模型,并用遺傳算法求解,從而根據(jù)路段交通量與先驗(yàn)OD矩陣確定路網(wǎng)分配的初始OD矩陣。同時(shí)本文將路網(wǎng)OD矩陣分配得到的路段流量作為評價(jià)路網(wǎng)交通狀態(tài)的重要依據(jù),并將不同的禁限管理方法特別是轉(zhuǎn)向禁限通過權(quán)矩陣、通行能力矩陣以及路阻函數(shù)的改變與變形來使得管理方法在靜態(tài)分配中得以體現(xiàn)。并在算例路網(wǎng)中對禁限管理后的路網(wǎng)OD矩陣進(jìn)行重分配來判斷路網(wǎng)交通組織的優(yōu)化效果,從而給出禁限管理的適用性條件。
[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.
