【摘要】：隨著我國城市對環(huán)境的要求,以及構(gòu)建多方式綜合交通體系的需要,很多城市開始大力發(fā)展公共交通。環(huán)境友好型的現(xiàn)代有軌電車交通系統(tǒng)是一種環(huán)保、高效的中低運(yùn)量城市軌道交通系統(tǒng),因其具有建設(shè)成本低、建設(shè)周期短、運(yùn)行速度快、舒適度高、節(jié)能節(jié)地等突出優(yōu)點(diǎn),在國外發(fā)達(dá)城市已經(jīng)得到大量應(yīng)用。我國現(xiàn)代有軌電車剛剛處于起步階段,由于我國的交通環(huán)境復(fù)雜,無法直接應(yīng)用國外先進(jìn)的經(jīng)驗(yàn),導(dǎo)致在運(yùn)營管理過程中存在平交道口通行效率低、安全隱患多等嚴(yán)峻問題�，F(xiàn)代有軌電車系統(tǒng)是后加入的地面公共交通,有軌電車的加入會(huì)改變原來的道路交通規(guī)劃、管理、控制,會(huì)對社會(huì)交通造成干擾,合理的交通信號控制將可以提高整體交通運(yùn)行效率。本文從智能交通控制的角度出發(fā),依托北京市科技計(jì)劃課題《現(xiàn)代有軌電車運(yùn)行協(xié)同智能管控系統(tǒng)研究》,以分析現(xiàn)代有軌電車特征為基礎(chǔ),展開現(xiàn)代有軌電車信號優(yōu)先控制方法的研究,實(shí)現(xiàn)有軌電車的預(yù)期運(yùn)營效果,保障有軌電車的運(yùn)營安全。課題首先分析了現(xiàn)代有軌電車的基本車輛技術(shù)特征、運(yùn)行狀態(tài)、調(diào)度規(guī)律以及站點(diǎn)設(shè)置等客觀因素,研究了現(xiàn)代有軌電車在交叉路口與社會(huì)車流的沖突關(guān)系以及有軌電車的加入對交通信號控制的影響,并根據(jù)有軌電車在交叉口不同的行駛狀態(tài),得出了現(xiàn)代有軌電車相位最小綠燈時(shí)間計(jì)算方法。結(jié)合現(xiàn)代有軌電車車輛的優(yōu)先等級和控制要求,重點(diǎn)研究現(xiàn)代有軌電車車輛在平交道口下的被動(dòng)優(yōu)先、絕對優(yōu)先、完全優(yōu)先、部分優(yōu)先等各種優(yōu)先策略,并以典型四相位信號控制為例,建立了現(xiàn)代有軌電車的交叉口控制模型。在現(xiàn)代有軌電車運(yùn)行特性的基礎(chǔ)上通過列車定位技術(shù)及交通流檢測技術(shù)獲取列車實(shí)時(shí)定位信息及交通流信息,結(jié)合有軌電車行車計(jì)劃,基于有軌電車安全保障技術(shù),建立了有軌電車的停車線到達(dá)時(shí)間預(yù)測模型,提出現(xiàn)代有軌電車協(xié)同優(yōu)先控制算法,從區(qū)域控制的角度實(shí)現(xiàn)信號優(yōu)先,降低信號優(yōu)先對區(qū)域交通的影響,實(shí)現(xiàn)有軌電車的線路協(xié)同優(yōu)先通行,提升有軌電車及道路交通的整體運(yùn)營效益。本文最后以沈陽渾南新區(qū)現(xiàn)代有軌電車線路為分析案例,選取部分區(qū)間進(jìn)行仿真實(shí)驗(yàn)。對比分析實(shí)施信號優(yōu)先前后,有軌電車以及社會(huì)車流的旅行速度、停車延誤等。
[Abstract]:With the environmental requirements of Chinese cities and the need to build a multi-mode integrated transportation system, many cities began to vigorously develop public transport. The environment-friendly modern tram transportation system is an environmental protection. High efficiency urban rail transit system with low cost, short construction period, fast running speed, high comfort, energy saving and land saving advantages. The modern tram in our country is just in its infancy, because the traffic environment of our country is complex, it is impossible to apply the advanced experience of foreign countries directly. In the process of operation and management there are serious problems such as low efficiency of level crossing and many hidden safety problems. The modern tram system is the ground public transportation after joining. The introduction of trams will change the original road traffic planning, management and control, and will interfere with social traffic. Reasonable traffic signal control will improve the overall traffic efficiency. From the perspective of intelligent traffic control, this paper relies on the Beijing science and technology project "modern tram operation cooperative intelligent management and control system research". Based on the analysis of the characteristics of modern tram, the research on signal priority control method of modern tram is carried out to realize the expected operation effect of tram. First of all, the paper analyzes the basic vehicle technical characteristics, running state, dispatching law and station setting of modern tram. This paper studies the conflict relationship between modern tram at intersection and social traffic flow and the influence of tram on traffic signal control, and according to the different driving state of tram at intersection. The calculation method of phase minimum green time of modern tram is obtained. Combined with the priority grade and control requirement of modern tram vehicle, the passive priority of modern tram vehicle under horizontal crossing is studied emphatically. Absolute priority, complete priority, partial priority and other priority strategies, and take typical four-phase signal control as an example. The intersection control model of modern tram is established. Based on the operation characteristics of modern tram, the real-time location information and traffic flow information are obtained by train positioning technology and traffic flow detection technology. Based on the tram safety and security technology, a model for predicting the arrival time of the tram stop line is established, and a collaborative priority control algorithm for modern tram is proposed. From the point of view of regional control, signal priority is realized, and the influence of signal priority on regional traffic is reduced. Finally, taking the modern tram line in Hunnan New District of Shenyang as an analysis case, selected parts of the section to carry out simulation experiments, and compared the implementation of signal before and after priority. Trams and social traffic travel speed, parking delays and so on.
