【摘要】：公共交通是緩解城市交通壓力的重要途徑�，F(xiàn)代有軌電車作為城市公共交通的一種,經(jīng)過(guò)全面的技術(shù)升級(jí),近年來(lái)又逐漸受到人們的青睞。目前,我國(guó)很多城市都在規(guī)劃、建設(shè)有軌電車系統(tǒng)。但是,多數(shù)有軌電車的線路是布設(shè)在道路平面上的,其在交叉口信號(hào)控制方式的選擇對(duì)確保有軌電車的高效運(yùn)行,提高運(yùn)營(yíng)服務(wù)水平,降低交叉口的整體延誤具有重要影響。本文首先敘述了有軌電車的運(yùn)行特性和運(yùn)行的交通條件,同時(shí)對(duì)有軌電車的信號(hào)控制流程和信號(hào)優(yōu)先控制系統(tǒng)做了簡(jiǎn)要的概述。在有軌電車采取主動(dòng)式信號(hào)優(yōu)先控制策略的情況下,以交叉口各進(jìn)口道的車輛延誤為基礎(chǔ),建立了考慮所有人員的延誤和人均延誤損失的交叉口整體效益函數(shù)。并充分考慮有軌電車離站時(shí)刻和交叉口信號(hào)優(yōu)先方案間的內(nèi)在聯(lián)系,建立了一種組合控制策略。即將站臺(tái)控制模式(即刻離站或滯站調(diào)度)作為一種優(yōu)先反應(yīng)的控制方式,分析得出了各組合控制策略(即刻離站、即刻離站+綠燈延長(zhǎng)、即刻離站+相位插入、即刻離站+相位旋轉(zhuǎn)、即刻離站+綠燈提前)在交叉口的延誤模型,并給出了交叉口整體效益函數(shù)的計(jì)算公式。比較各組合控制策略和有軌電車滯站調(diào)度的效益值大小,并選擇效益最優(yōu)的控制策略為有軌電車提供優(yōu)先權(quán)。該策略在使有軌電車獲得優(yōu)先權(quán)、發(fā)揮其最佳運(yùn)營(yíng)效益的同時(shí),也降低了對(duì)社會(huì)其他車輛的影響,使交叉口的延誤損失降至最低。同時(shí)降低了有軌電車在站臺(tái)停靠時(shí)間這一不確定性因素對(duì)有軌電車信號(hào)優(yōu)先系統(tǒng)和調(diào)度系統(tǒng)的影響。本文最后以蘇州市有軌電車一號(hào)線金楓路與何山路交叉口為例,對(duì)各組合控制策略的效益函數(shù)進(jìn)行實(shí)例應(yīng)用,分析了有軌電車在信號(hào)區(qū)間的任意時(shí)刻到達(dá)交叉口,組合控制策略的選擇情況。并以效益函數(shù)最小為目標(biāo)函數(shù)對(duì)信號(hào)配時(shí)進(jìn)行了優(yōu)化。
[Abstract]:Public transportation is an important way to relieve the pressure of urban traffic. As a kind of urban public transportation, modern tram has been gradually favored by people in recent years after comprehensive technological upgrading. At present, many cities in our country are planning. However, most tram lines are located on the road plane, and the choice of signal control mode at intersections can ensure the efficient operation of trams and improve the level of operation and service. It is important to reduce the overall delay at intersections. This paper first describes the operation characteristics and traffic conditions of trams. At the same time, the signal control flow and signal priority control system of tram are briefly summarized. Having established an overall benefit function at intersections that takes into account delays for all personnel and loss of delay per person, and taking fully into account the inherent links between the tram departure time and the signal priority programme at the intersection, In this paper, a combined control strategy is established, which means that the platform control mode (immediate or delayed station dispatching) is considered as a priority response control mode, and the combined control strategy (instant exit, instant exit green light extension) is obtained. The delay model of instant off-station phase insertion, instant off-station phase rotation, instant exit green light advance) at the intersection, The calculation formula of the whole benefit function of intersection is given, and the value of the combined control strategy and the benefit value of tram stop station dispatching are compared. The optimal control strategy is chosen to provide priority for trams. This strategy not only gives priority to trams, but also reduces the impact on other vehicles in society. The delay loss at the intersection is minimized and the uncertain factor of the tram stop time on the platform is reduced. The signal priority system and the dispatching system of the tram are also reduced. Finally, the paper uses Suzhou tram as the example. For example, the intersection of Jinfeng Road and he Shan Road on Line 1, The benefit function of the combined control strategy is applied to analyze the tram arriving at the intersection at any time in the signal interval. The selection of combinatorial control strategy and the optimization of signal timing with the minimum benefit function as the objective function are also presented.
