【摘要】：近年來,隨著我國社會經(jīng)濟和城市經(jīng)濟快速發(fā)展,致使城市化水平不斷提高,城市人口大量增長,城市交通問題日益嚴重,而發(fā)展公共交通作為當(dāng)今緩解城市交通壓力的方式已成為共識。同時,經(jīng)過全面的技術(shù)升級,沉寂百余年之久的有軌電車又重新登上了改善城市交通的歷史舞臺�，F(xiàn)代有軌電車作為一種新型的公共交通工具,與傳統(tǒng)的公共交通工具相比,車輛外觀靚麗,在技術(shù)裝備上融入諸多現(xiàn)代化高科技元素,具備更高的運行速度、更舒適的乘車空間以及快捷的換乘方式,已成為城市公共交通不可或缺的一部分。目前,我國的很多城市都在規(guī)劃建設(shè)現(xiàn)代有軌電車系統(tǒng)。但是,有軌電車相比于社會車輛、常規(guī)公交和輕軌等交通方式有其獨特的行駛特性,尤其對于有軌電車平交路口信號的控制方式,對確保有軌電車的高效運行,提高有軌電車的服務(wù)水平,降低乘客在平交路口的延誤具有重要意義。因此,本文首先深入研究了現(xiàn)代有軌電車及城市交通信號控制理論基礎(chǔ);同時為了有軌電車在平交路口信號優(yōu)先控制獲取有效的車輛信息,文中研究了有軌電車信號優(yōu)先車輛檢測技術(shù),并針對環(huán)形線圈車輛檢測技術(shù)研究了其工作原理,對環(huán)形線圈車輛檢測器的硬件進行設(shè)計,結(jié)合硬件通過系統(tǒng)功能需求分析對軟件進行了設(shè)計,實現(xiàn)為有軌電車交叉口信號優(yōu)先控制提供車輛信息;進而,作為論文研究的重點,文中對有軌電車交叉口信號優(yōu)先控制策略進行了設(shè)計,詳細敘述了被動式信號優(yōu)先控制策略與主動式信號優(yōu)先控制策略。其中,為了確保交叉口有軌電車的優(yōu)先通行,主動式信號優(yōu)先將是本文研究的重中之重。而主動式信號優(yōu)先包括絕對優(yōu)先、完全優(yōu)先、部分優(yōu)先和實時優(yōu)先,文中對這些優(yōu)先策略的控制邏輯與流程進行了詳細描述與設(shè)計;同時,為了更好對交叉口信號控制,獲取有效地有軌電車通過交叉口的車輛信息是必不可少的,文中研究了交叉口信號優(yōu)先車輛檢測設(shè)備的設(shè)置位置,并給出了設(shè)置實例。研究了有軌電車交叉口信號優(yōu)先控制策略,同時在考量研究成本、時間及可行性的情形下,本文選擇模擬仿真作為本文的研究方法。根據(jù)研究理論,以固定配時信號控制為基礎(chǔ),將本文構(gòu)建的絕對優(yōu)先、完全優(yōu)先、部分優(yōu)先3種優(yōu)先策略,以微觀交通仿真軟件VISSIM為模擬平臺,建立單點交叉口路網(wǎng)仿真模型,模擬不同的同向交通量、橫向交通量與有軌電車不同班次的組合情景下,分析有軌電車、同向社會車輛、橫向社會車輛的延誤,綜合比較信號優(yōu)先控制策略的適用范圍,并決定各種情景下的最佳控制策略,歸納結(jié)論和建議,作為實際應(yīng)用的參考。
[Abstract]:In recent years, with the rapid development of our country's social economy and urban economy, the level of urbanization has been continuously improved, the urban population has increased a lot, and the urban traffic problems have become more and more serious. The development of public transport as a way to relieve the pressure of urban traffic has become a consensus. At the same time, after a comprehensive technological upgrading, trams, which have been silent for more than a hundred years, have once again stepped onto the historical stage of improving urban traffic. As a new type of public transport vehicle, modern tram has a beautiful appearance compared with traditional public transport, and has a higher running speed by incorporating many modern high-tech elements into its technical equipment. More comfortable ride space and fast transfer mode have become an indispensable part of urban public transport. At present, many cities in our country are planning to build a modern tram system. However, compared with social vehicles, conventional public transport and light rail transportation modes have their unique driving characteristics, especially for the control of tram intersection signals, to ensure the efficient operation of trams. It is of great significance to improve the service level of tram and reduce the delay of passengers at the intersection. Therefore, in this paper, the theoretical foundation of modern tram and urban traffic signal control is deeply studied, and in order to obtain effective vehicle information for tram signal priority control at intersection, In this paper, the detection technology of tram signal priority vehicle is studied, and the working principle of the loop coil vehicle detection technology is studied, and the hardware of the loop coil vehicle detector is designed. The software is designed to provide vehicle information for the signal priority control of tram intersection through the analysis of the system function requirements of the hardware, and then, as the focus of the paper, In this paper, the signal priority control strategy of tram intersection is designed, and the passive signal priority control strategy and the active signal priority control strategy are described in detail. In order to ensure the priority of tram at intersections, the priority of active signal will be the most important in this paper. The active signal priority includes absolute priority, complete priority, partial priority and real-time priority. The control logic and process of these priority strategies are described and designed in detail. It is essential to obtain the vehicle information of tram crossing effectively. This paper studies the setting position of signal-priority vehicle detection equipment at intersection and gives an example of setting up. The signal priority control strategy of tram intersection is studied. At the same time, under the consideration of research cost, time and feasibility, simulation is chosen as the research method in this paper. According to the research theory, on the basis of fixed timing signal control, three priority strategies, absolute priority, complete priority and partial priority, are constructed in this paper. The simulation model of single point intersection road network is established on the platform of microscopic traffic simulation software VISSIM. Under the simulation of different codirectional traffic volume, transverse traffic volume and different frequency of tram, the delay of tram, codirectional social vehicle and lateral social vehicle is analyzed, and the applicable range of signal priority control strategy is compared synthetically. The optimal control strategy, conclusions and suggestions are determined for practical application.
