【摘要】：隨著我國經(jīng)濟(jì)的持續(xù)快速發(fā)展,交通需求的增長速度明顯高于道路資源增長的速度,我國許多大城市面臨著日益嚴(yán)重的交通擁堵問題。公共交通作為運(yùn)輸效率極高的交通方式,是解決城市擁堵問題的一個重要的方式,公交優(yōu)先也成為了國內(nèi)外交通學(xué)者的研究熱點(diǎn)。本文將以城市主干道為研究對象,研究如何通過信號控制的方法實(shí)現(xiàn)公交優(yōu)先。 本文所做的工作包括以下幾個方面： 1、對公交優(yōu)先的信號控制的基礎(chǔ)理論進(jìn)行了全面的研究,重點(diǎn)闡述了被動優(yōu)先及主動優(yōu)先兩種優(yōu)先控制策略的實(shí)現(xiàn)方法,作為本文研究的理論基礎(chǔ)。 2、以城市主干道為研究對象,對被動式線控系統(tǒng)中的幾個關(guān)鍵參數(shù)——周期、綠信比和相位差進(jìn)行研究,以人均延誤最小為目的,加入公交優(yōu)先作為控制條件,建立各個參數(shù)的優(yōu)化模型,得出基于公交優(yōu)先的城市主干道信號控制優(yōu)化方案。在此控制方案基礎(chǔ)上,引入公交車組的理論,建立公交車輛的優(yōu)先規(guī)則,在交叉口中對公交車采用主動優(yōu)先的方法,在對協(xié)調(diào)控制系統(tǒng)影響較小的情況下對公交車輛實(shí)施主動優(yōu)先。 3、以中山市中山路為仿真對象,建立兩套仿真優(yōu)化控制方案,在VISSIM軟件中對本文提出的公交優(yōu)先信號協(xié)調(diào)控制方案及公交車組的實(shí)施效益進(jìn)行評價。
[Abstract]:With the continuous and rapid development of China's economy, the growth rate of traffic demand is obviously higher than that of road resources, and many large cities in China are faced with increasingly serious traffic congestion problems. As a highly efficient mode of transportation, public transport is an important way to solve the problem of urban congestion. Public transport priority has also become a research hotspot of domestic and foreign traffic scholars. This article will take the city main road as the research object, study how to realize the bus priority through the signal control method. The work done in this paper includes the following aspects: 1. The basic theory of bus priority signal control is studied comprehensively, and the realization methods of passive priority and active priority are emphasized. As the theoretical basis of this paper. 2. Taking the city main road as the research object, the paper studies several key parameters in the passive line control system-cycle, green signal ratio and phase difference. In order to minimize the delay per capita, bus priority is added as the control condition, and the key parameters of the passive line control system are studied, which are the cycle, the green signal ratio and the phase difference. The optimization model of each parameter is established, and the signal control optimization scheme of urban trunk road based on bus priority is obtained. On the basis of this control scheme, the theory of bus group is introduced, the priority rule of bus is established, and the active priority method is adopted to the bus in the crossing port. In the case of small impact on the coordinated control system, active priority is given to public transport vehicles. Thirdly, taking Zhongshan Road in Zhongshan City as the simulation object, two sets of simulation optimization control schemes are set up, and the coordinated control scheme of bus priority signal and the implementation benefit of bus train set are evaluated in VISSIM software.
