【摘要】：交通路網(wǎng)作為社會(huì)發(fā)展的一個(gè)主要服務(wù)載體，其穩(wěn)定性是與國(guó)家經(jīng)濟(jì)發(fā)展直接相關(guān)的。城市在不斷發(fā)展，道路交通的擁堵問(wèn)題日益嚴(yán)重，逐步從單一的路段或者交叉口擁擠問(wèn)題演化為片區(qū)道路的擁堵。為了將這一問(wèn)題解決，本論文從以下幾個(gè)方面對(duì)城市道路交通狀況進(jìn)行分析研究。 首先，，本文針對(duì)國(guó)內(nèi)外交通狀態(tài)的研究狀況進(jìn)行概述，對(duì)于中外學(xué)者及專(zhuān)家對(duì)城市道路交通運(yùn)行狀態(tài)評(píng)價(jià)方法的研究，進(jìn)行進(jìn)一步的總結(jié)歸納。根據(jù)以往研究?jī)?nèi)容能夠看出，要分析道路的交通狀態(tài)情況，單純依據(jù)單點(diǎn)交叉口或路段的交通狀況來(lái)評(píng)價(jià)片區(qū)甚至整個(gè)路網(wǎng)的交通狀況是不全面的，因此，需要對(duì)某個(gè)片區(qū)，甚至片區(qū)路網(wǎng)整體的交通狀態(tài)進(jìn)行評(píng)價(jià)分析。 其次，闡述了專(zhuān)家學(xué)者針對(duì)交叉口延誤及車(chē)輛排隊(duì)的幾種常見(jiàn)模型，以烏魯木齊市友好北路與新醫(yī)路交叉口為例，借助VISSIM微觀仿真軟件與數(shù)學(xué)延誤模型，將仿真結(jié)果中的排隊(duì)長(zhǎng)度、延誤和行程時(shí)間等數(shù)據(jù)，與Webster延誤模型計(jì)算結(jié)果進(jìn)行比對(duì)，進(jìn)而確定交叉口延誤值，對(duì)交叉口的交通運(yùn)行狀態(tài)進(jìn)行分析。 最后，分別以烏魯木齊市高新區(qū)、克拉瑪依市老城區(qū)為例，對(duì)片區(qū)道路交通狀況進(jìn)行分析，提出以片區(qū)交叉口進(jìn)口飽和度、路段平均行車(chē)速度作為交通狀態(tài)評(píng)價(jià)指標(biāo)，以一種新的基于交通狀態(tài)系數(shù)的道路交通運(yùn)行狀態(tài)評(píng)價(jià)方法，借助VISSIM仿真模型輸出的相關(guān)評(píng)價(jià)數(shù)據(jù)，探討分析該評(píng)價(jià)方法是否適用于對(duì)片區(qū)道路交通運(yùn)行狀態(tài)的評(píng)價(jià)。
[Abstract]:Traffic network as a main service carrier of social development, its stability is directly related to the national economic development. In order to solve this problem, the traffic situation of urban roads is analyzed and studied from the following aspects. First of all, this paper summarizes the research situation of traffic status at home and abroad, and studies the evaluation methods of urban road traffic operation state by Chinese and foreign scholars and experts. According to the previous research content, we should analyze the traffic condition of the road. It is not comprehensive to evaluate the traffic condition of the whole road network or even the whole area based on the traffic condition of the single point intersection or the section of road. Therefore, it is necessary to evaluate the traffic condition of a certain area. Even the whole traffic state of the whole area road network is evaluated and analyzed. Secondly, this paper expounds several common models of intersection delay and vehicle queue, taking the intersection of friendly North Road and Xinyi Road in Urumqi as an example. With the help of VISSIM simulation software and mathematical delay model, the data of queue length, delay and travel time in the simulation results are compared with the calculated results of Webster delay model. Then the delay value of intersection is determined, and the traffic state of intersection is analyzed. Finally, taking Urumqi High-tech Zone and Karamay City as an example, the paper analyzes the road traffic situation of the district, and puts forward the saturation of the intersection entrance. As an index of traffic state evaluation, a new evaluation method based on traffic state coefficient is used to evaluate the road traffic running state, and the relevant evaluation data are outputted by VISSIM simulation model. This paper discusses whether the evaluation method is applicable to the evaluation of the road traffic running state in the area.
