【摘要】：伴隨著我國(guó)經(jīng)濟(jì)水平的快速發(fā)展和城市化進(jìn)程的不斷加快,城市機(jī)動(dòng)車保有量越來越大,而道路基礎(chǔ)設(shè)施的建設(shè)速度遠(yuǎn)遠(yuǎn)不能滿足不斷增長(zhǎng)的交通需求,由此帶來了交通擁堵、尾氣污染、交通事故等一系列的城市交通問題。干線信號(hào)協(xié)調(diào)控制和公交優(yōu)先策略在當(dāng)代社會(huì)被認(rèn)為是解決城市交通問題的兩種重要方法。干線信號(hào)協(xié)調(diào)控制可以通過各交叉口之間的協(xié)調(diào)聯(lián)動(dòng)來實(shí)現(xiàn)干線交通流的連續(xù)運(yùn)行,從而提高干線的通行能力,緩解交通擁堵。公交優(yōu)先可以保障公交車輛的優(yōu)先通行,減少公交車延誤,從而提高公交車的服務(wù)水平。然而,干線信號(hào)協(xié)調(diào)控制與公交優(yōu)先策略所追求的效益不同,前者追求社會(huì)車輛的效益最大,而后者只追求公交車輛的效益最大。因此,在干線協(xié)調(diào)下實(shí)施公交優(yōu)先時(shí),公交車輛和社會(huì)車輛的利益會(huì)相互干擾,而前人對(duì)這一現(xiàn)象的研究尚有一些不足之處,鑒于此,本文展開了學(xué)術(shù)研究。本文首先闡述了干線信號(hào)協(xié)調(diào)控制和公交優(yōu)先策略的相關(guān)基礎(chǔ)理論,為干線協(xié)調(diào)下的公交優(yōu)先研究奠定理論基礎(chǔ);接著以合肥市望江西路為例在交通仿真軟件VISSIM上進(jìn)行干線協(xié)調(diào)下公交優(yōu)先的實(shí)例仿真研究,將此干線上的公交車占社會(huì)車輛的比例、公交車的發(fā)車頻率、公交車在各站點(diǎn)的平均停靠時(shí)間作為三個(gè)關(guān)鍵因素,根據(jù)綜合交通效益指標(biāo)(PI)的結(jié)果進(jìn)行適宜性分析,探究在干線協(xié)調(diào)下最適宜實(shí)施公交優(yōu)先的狀況;最后基于適宜性分析的結(jié)果,對(duì)干線信號(hào)協(xié)調(diào)控制方案和公交優(yōu)先方案分別進(jìn)行優(yōu)化,從而提高干線的整體通行效率。
[Abstract]:With the rapid development of our country's economic level and the accelerating process of urbanization, the number of urban motor vehicles is increasing, and the construction speed of road infrastructure is far from meeting the increasing traffic demand, which brings traffic congestion. Tail gas pollution, A series of urban traffic problems, such as traffic accidents, are considered to be two important methods to solve urban traffic problems in modern society. The coordination and linkage between the forks to realize the continuous operation of the trunk traffic flow, So as to improve the traffic capacity of the trunk lines, alleviate traffic congestion. Bus priority can protect the priority of public transport vehicles, reduce bus delays, thereby improving the bus service level. The coordinated control of trunk signals is different from the benefits pursued by the bus priority strategy. The former pursues the greatest benefits of social vehicles, while the latter only pursues the greatest benefits of public transport vehicles. Therefore, when implementing public transport priority under the coordination of trunk lines, The interests of public transport vehicles and social vehicles will interfere with each other, but previous studies on this phenomenon have some shortcomings, in view of this, In this paper, academic research has been carried out. Firstly, the related basic theories of trunk signal coordination control and bus priority strategy have been expounded in this paper, which will lay a theoretical foundation for the study of bus priority under trunk line coordination. Then take Wangjiang West Road in Hefei City as an example to carry out the simulation study of bus priority under the coordination of trunk lines on the traffic simulation software VISSIM. The proportion of buses on this trunk line to social vehicles and the departure frequency of buses are put forward. As three key factors, the average stop time of bus in each station is analyzed according to the result of comprehensive traffic benefit index (PI), and the condition that bus priority is best implemented under the coordination of trunk lines is explored. Finally, based on the results of suitability analysis, the coordinated control scheme of trunk line signal and the bus priority scheme are optimized respectively, so as to improve the overall traffic efficiency of the trunk line.
