【摘要】：在汽車行駛過(guò)程中,強(qiáng)行并線會(huì)對(duì)城市道路交通帶來(lái)不利影響,也易造成交通事故。近年來(lái)隨著我國(guó)機(jī)動(dòng)車保有量的持續(xù)增長(zhǎng),城市道路強(qiáng)行并線問(wèn)題愈發(fā)明顯。本文根據(jù)強(qiáng)行并線的特性給出了城市道路強(qiáng)行并線的定義,并對(duì)其進(jìn)行了解釋。在對(duì)車輛并線軌跡進(jìn)行分析之后,確定了對(duì)城市道路強(qiáng)行并線的判定方法:在自由流、穩(wěn)定流、飽和流時(shí)可依據(jù)并線安全車距進(jìn)行判斷;在強(qiáng)制流情況下,應(yīng)當(dāng)主要依據(jù)并線動(dòng)作的突然性進(jìn)行判斷。安全車距分為高車速下的安全車距和低車速下的安全車距,兩者以30km/h為分界線。在推導(dǎo)出并線安全車距后,給出了并線安全車距值,可作為判定強(qiáng)行并線的參考。對(duì)于并線動(dòng)作的突然性,主要從轉(zhuǎn)向燈使用、并線行為車的加速度、速度和并線轉(zhuǎn)角三方面綜合考量。另外,從道路通行能力、行車舒適性的角度出發(fā),本文還提出了一種根據(jù)后車車速變化百分比來(lái)判定強(qiáng)行并線的設(shè)想。城市道路強(qiáng)行并線產(chǎn)生的原因主要有駕駛員安全意識(shí)、法制意識(shí)淡薄,新手駕駛員較多,城市道路交通擁堵等;根據(jù)行駛速度、并線動(dòng)機(jī)、并線路段等可將城市道路強(qiáng)行并線作多種劃分。在對(duì)西安市多條城市道路進(jìn)行調(diào)查統(tǒng)計(jì)后,總結(jié)出了城市道路強(qiáng)行并線的規(guī)律,用強(qiáng)行并線與正常并線進(jìn)行對(duì)比,計(jì)算出了西安市強(qiáng)行并線、正常并線發(fā)生率,統(tǒng)計(jì)出了西安市強(qiáng)行并線與正常并線用時(shí)和轉(zhuǎn)向燈的使用率,總結(jié)出了城市道路強(qiáng)行并線與車型的關(guān)系和車道分布規(guī)律;測(cè)出了強(qiáng)行并線前后車的速度,并對(duì)前后車速度關(guān)系進(jìn)行了分析。本文運(yùn)用交通沖突理論從車輛頻繁強(qiáng)行并線、交叉口車輛強(qiáng)行并線以及不穩(wěn)定流狀態(tài)車輛強(qiáng)行并線分析了強(qiáng)行并線對(duì)城市道路安全性的影響,以四個(gè)強(qiáng)行并線引發(fā)的城市道路交通事故做了例證,并針對(duì)城市道路強(qiáng)行并線提出了防治措施與建議。
[Abstract]:In the process of automobile driving, the forced merging of lines will bring adverse effects on urban road traffic, and will easily cause traffic accidents. In recent years, with the continuous increase of the number of motor vehicles in China, The problem of forced alignment of urban roads is becoming more and more obvious. This paper gives the definition and explanation of forced alignment of urban roads according to the characteristics of forced merging lines. The method of determining the forced alignment of urban roads is determined: in the case of free flow, steady flow and saturated flow, the judgment can be made according to the safety distance of the parallel line, and in the case of forced flow, The safe vehicle distance is divided into high speed safe car distance and low speed safe car distance. The 30km/h is the dividing line between them. After deducing the parallel line safe car distance, the safety car distance value of parallel line is given, which is divided into two parts: one is the safety vehicle distance at the high speed and the other is the safe car distance at the low speed. It can be used as a reference to judge the forced merging line. For the sudden action of parallel line, it is mainly considered from the angle of acceleration, speed and angle of the vehicle. In addition, from the capacity of the road, the traffic capacity is taken into account in the use of the turn signal, the acceleration, the speed and the angle of the parallel line of the vehicle. From the point of view of driving comfort, this paper also puts forward a tentative idea to judge the forced merging line according to the percentage of change of the rear vehicle speed. The main reasons for the forced merging line in urban roads are the driver's safety consciousness and the weak awareness of the legal system. There are more novice drivers, traffic jams on urban roads, and so on. According to the speed of driving, the motive of parallel lines, and so on, the urban roads can be forced to be divided into many kinds of lines. After the investigation and statistics of many urban roads in Xi'an, This paper sums up the law of forced merging line of urban road, compares it with normal parallel line, calculates the incidence of forced merging line and normal parallel line in Xi'an city. The usage rate of the forced and normal parallel lines and turn signals in Xi'an is calculated, the relationship between the forced parallel lines of urban roads and vehicle models and the distribution law of lanes are summed up, and the speed of vehicles before and after the forced merging lines are measured. Based on the traffic conflict theory, this paper analyzes the influence of traffic conflict on the safety of urban roads from the point of view of the frequent forced merging of vehicles, the forced merging of vehicles at intersections and the forced merging lines of vehicles in unstable flow state. In this paper, the urban road traffic accidents caused by four forced merging lines are exemplified, and the preventive measures and suggestions are put forward.
