公交客车分区域站立密度分布特征

为分析公交客车车厢内站立密度分布的不均匀性,通过调查西安7条线路平峰、高峰的客流量,提出了车厢内站立乘客流的变化特征.基于不同座椅布置模式,分析了不均匀性的起因、分布特征及相互间的关联性,确定了各特征区间内的最大站立密度区域,分析了在乘客选择站立区域的倾向性.结果表明,第一次驻足在B区域和C区域的选择倾向性比重占93.23%;当车厢平均站立密度ρ超过6人/m2时,"轴距1+1后通道1+1"和"轴距1+1后通道2+2"座椅布置的最大站立密度区域分别是B区域和C区域;选择C区域站立的倾向性比重在车厢内站立密度ρ不超过2人/m2时降幅明显,当乘客选择倾向性比重降至40% 后降幅趋缓. 

An Analysis of Rider Density Distribution at Different Parts of Public Buses

To analyze inhomogeneity of density distributions in different areas of public buses,characteristics of standing density of passenger flow is studied through a investigation of 7 crowded bus routes in both off-peak hours and peak hours.Based on different layouts of seats,causes of inhomogeneity,distribution characteristics,and correlation within each other are analyzed.The parts have maximum standing density in each feature interval are verified.Tendency of passengers to choose standing areas are analyzed.The results show that,after get on a bus passengers firstly choose to settle down in area B or C,the possibility is 93.23%.When the average standing density ρin a bus exceeds 6 persons per m2,the maximum of standing density is in area B and C,as the layouts of seats are"1+1 on wheelbase,1+1 on posteri-or passage"or"1+1 on wheelbase,2+2 on posterior passage".When ρranges from 0 to 2 persons per meter2,propor-tion of standing density in area C decreases significantly.When it reaches 40%,the decrease tends to slow dow n.
