【摘要】：信號控制交叉口是城市交通系統(tǒng)的重要節(jié)點(diǎn)，最能體現(xiàn)我國城市混合交通的特征。大量機(jī)動車、非機(jī)動車和行人在交叉口匯集通過，使交叉口成為了交通沖突的匯集地。行人和機(jī)動車的沖突越來越嚴(yán)重，不但降低了交叉口的通行效率，導(dǎo)致了延誤，而且致使事故增多，影響整個交通系統(tǒng)的安全水平。行人是交通中的弱勢群體，且交通行為具有較大的隨意性，更容易受到傷害。本文對信號控制交叉口人行橫道處行人的交通特性進(jìn)行研究，通過人工觀測和視頻采集的方法進(jìn)行數(shù)據(jù)調(diào)查，分析行人的速度特性、到達(dá)規(guī)律和行人-機(jī)動車沖突特性。 從行人過街步速、需求空間、臨界時(shí)間間隙、可容忍等待時(shí)間以及行人過街時(shí)的行為方式和心理特征等方面對行人的交通特性進(jìn)行了分析和評述，并且對幾種行人交通微觀仿真模型進(jìn)行了對比評價(jià)。 通過實(shí)測數(shù)據(jù)對行人的步行速度進(jìn)行統(tǒng)計(jì)分析，得出行人步行速度的分布特征參數(shù)，并對影響行人步行速度的因素進(jìn)行分析，結(jié)果表明：性別不同、年齡不同時(shí)，行人的步行速度有差異，一起過街的行人群體的數(shù)量也對行人的步行速度有影響。對行人的到達(dá)規(guī)律進(jìn)行分析，，用數(shù)理統(tǒng)計(jì)中的離散分布進(jìn)行擬合并驗(yàn)證，認(rèn)為行人的到達(dá)規(guī)律符合負(fù)二項(xiàng)分布模型。 通過分析行人與機(jī)動車發(fā)生沖突的原因和沖突類型，基于二元Logistic回歸模型建立行人穿越機(jī)動車流時(shí)的可接受間隙模型，分析沖突對行人造成的延誤，并通過VISSIM對交叉口行人與機(jī)動車的沖突進(jìn)行仿真。
[Abstract]:The signal-controlled intersection is an important node of the urban traffic system, which can best reflect the characteristics of the urban mixed traffic in our country. A large number of motor vehicles, non-motor vehicles and pedestrians converge through the intersections. The traffic conflicts between pedestrians and motor vehicles are becoming more and more serious, which not only reduces the efficiency of intersections, leads to delays, but also increases the number of accidents. Pedestrian is a vulnerable group in traffic, and traffic behavior is random and vulnerable. This paper studies the traffic characteristics of pedestrians at signal-controlled intersections. By means of artificial observation and video capture, the velocity characteristics, arrival rules and pedestrian-vehicle conflict characteristics of pedestrians are analyzed. The pedestrian traffic characteristics are analyzed and commented from the following aspects: pedestrian walking speed, demand space, critical time interval, tolerable waiting time, pedestrian behavior and psychological characteristics, etc. Several microscopic simulation models of pedestrian traffic are compared and evaluated. Through the statistical analysis of pedestrian walking speed by measured data, the distribution characteristic parameters of pedestrian walking speed are obtained, and the factors influencing pedestrian walking speed are analyzed. The results show that: gender is different, age is different, The pedestrian walking speed is different, and the number of pedestrian groups crossing the street has an effect on the pedestrian walking speed. The regularity of pedestrian arrival is analyzed, and the discrete distribution in mathematical statistics is used to verify the pedestrian walking speed. It is considered that the arrival rule of pedestrians accords with the negative binomial distribution model. Based on the analysis of the causes and types of conflicts between pedestrians and motor vehicles, the acceptable gap model of pedestrians passing through vehicle flows is established based on the binary Logistic regression model, and the delay caused by conflicts is analyzed. The conflicts between pedestrians and motor vehicles at intersections are simulated by VISSIM.
