市域快慢车越行组织下乘客选择行为研究

快车对慢车的越行影响了市域轨道交通快慢车运营组织下乘客换乘选择行 为.本文考虑乘客的时间感知差异，按照乘客出行起讫点的车站种类划分乘客，建立出行 广义费用模型；采用了Logit 模型求解案例中各类乘客的路径选择概率，并分析影响因素 的灵敏度.结果表明：换乘时间感知系数或始发站发车间隔增加时，乘客选择需换乘路径 的概率减小而选择慢车直达的概率增加；乘客出行途经车站数量或快车越行慢车次数增 加时，乘客选择需换乘路径的概率增加而选择慢车直达的概率减小.说明快慢车运营方式 适用于线路较长且乘客出行距离较远的市域轨道交通，能诱发乘客为了节省出行时间而 选择可能需要换乘的快车.

Passenger Choice Behavior for Regional Rail Transit under Express/Local Operation with Overtaking

Passenger choice behavior for regional rail transit under Express/Local operation is affected if express trains overtake local trains. This paper sorts the passengers by the type of their origin-destination to obtain the optional choice set, and constructs a generalized cost model of passenger travel route considering perception difference of time; after that, Logit model is used to study passengers’selective probability under Express/Local operation; finally, sensitivity analyses of the influential factors show that: when transfer perception coefficient or the headway at origin station increases, selective probabilities of the routes with transfers decrease while those of the routes without transfers increase; when the number of stations covered by passengers’OD or the number that express trains overtake local trains increases, selective probabilities of the routes with transfers increase while those of the routes without transfers decrease, indicating that Express/ Local operation can attract more passengers to catch express trains for saving travel time though they may transfer one or two times.
