【摘要】:隨著北京市城市經(jīng)濟(jì)的發(fā)展,帶來(lái)了一系列社會(huì)問(wèn)題,其中交通擁堵成為北京市突出的社會(huì)問(wèn)題。信號(hào)交叉口作為城市道路的重要組成部分,在道路銜接中起著舉足輕重的作用。初步統(tǒng)計(jì)北京市五環(huán)之內(nèi)擁有信號(hào)交叉口2000余個(gè),,針對(duì)北京市信號(hào)交叉口進(jìn)行左轉(zhuǎn)掉頭車(chē)輛流釋放特性研究,對(duì)于緩解北京市交通擁堵具有十分重要的作用。 研究首先從信號(hào)交叉口車(chē)頭時(shí)距特性、信號(hào)交叉口交通工程設(shè)計(jì)、微觀仿真應(yīng)用三方面展開(kāi)國(guó)內(nèi)外研究綜述,確定論文研究方法及數(shù)據(jù)采集內(nèi)容。論文調(diào)研數(shù)據(jù)包括左轉(zhuǎn)掉頭車(chē)輛車(chē)頭時(shí)距及掉頭車(chē)輛運(yùn)行特性。研究選取6個(gè)具有左轉(zhuǎn)專(zhuān)用相位及左轉(zhuǎn)專(zhuān)用車(chē)道的信號(hào)交叉口,并依托北京市信號(hào)控制系統(tǒng)獲取信號(hào)交叉口交通流運(yùn)行視頻數(shù)據(jù),而后應(yīng)用車(chē)頭時(shí)距采集程序采集左轉(zhuǎn)車(chē)流車(chē)頭時(shí)距;應(yīng)用實(shí)驗(yàn)車(chē)搭載高精度GPS記錄車(chē)輛轉(zhuǎn)彎運(yùn)行速度及加速度數(shù)據(jù)。然后,圍繞左轉(zhuǎn)掉頭車(chē)輛車(chē)頭時(shí)距特性展開(kāi)研究,發(fā)現(xiàn)左轉(zhuǎn)掉頭車(chē)輛車(chē)頭時(shí)距明顯大于左轉(zhuǎn)車(chē)輛車(chē)頭時(shí)距;不同排隊(duì)位置左轉(zhuǎn)掉頭車(chē)輛對(duì)左轉(zhuǎn)車(chē)流車(chē)頭時(shí)距分布影響不同;左轉(zhuǎn)掉頭車(chē)輛數(shù)量及在車(chē)隊(duì)中所處位置對(duì)左轉(zhuǎn)車(chē)流運(yùn)行延誤有著重要影響。最后采用交通仿真研究表明車(chē)流運(yùn)行延誤與左轉(zhuǎn)掉頭車(chē)輛所占比例呈對(duì)數(shù)增長(zhǎng)關(guān)系,并給出計(jì)算模型。
[Abstract]:With the development of Beijing's urban economy, a series of social problems have been brought, among which traffic congestion has become a prominent social problem in Beijing. As an important part of urban road, signalized intersection plays an important role in road convergence. There are more than 2000 signalized intersections in the Fifth Ring Road of Beijing. It is very important to study the flow release characteristics of left-turn U-turn vehicles at the signalized intersections in Beijing, which plays an important role in alleviating traffic congestion in Beijing. In this paper, the characteristics of the headway of signalized intersections, the traffic engineering design of signalized intersections, and the application of microscopic simulation are summarized firstly, and the research methods and data acquisition contents are determined. The research data of this paper include the headway distance and the running characteristics of the turning-around vehicle. In this paper, six signalized intersections with left turn phase and left turn lane are selected, and traffic flow video data are obtained by Beijing signal control system. Then the head-length acquisition program is used to collect the head-length of the left-turn flow, and the high-precision GPS is used to record the turning speed and acceleration data of the vehicle. Then, based on the study of the head-length characteristics of left-turn turning vehicle, it is found that the head-time distance of left-turn turning vehicle is obviously larger than that of left turn vehicle, and the influence of left-turn vehicle on left-turn flow head-length distribution is different at different queuing positions. The number of left-turn vehicles and their position in the vehicle fleet have an important impact on the left-turn traffic delay. Finally, the traffic simulation results show that there is a logarithmic relationship between the traffic delay and the proportion of the left-turn turning vehicle, and the calculation model is given.
