Analysis on the preference intention and its influencing factors of standing passengers in subway carriages

Abstract

Rail transit is an important part of urban public transportation and subway bears most of the urban public transportation volume as an important part of urban rail. The uneven density of standing seats in subway cars has always been a common problem. Passengers accustomed to gathering at the door will not only reduce the capacity of the vehicle, but also affect the comfort of passengers. The distribution of passengers in the compartment is affected by the passenger's personal attributes, travel characteristics and the layout of the facilities in the compartment. The first two types are subjective uncontrollable factors, while the third type of layout belongs to objective environmental factors.In this study, the factors influencing the position selection of standing passengers are focused on the differentiated layout of the compartment, and the standing space inside the compartment is divided into three areas, namely the door area, the transition area and the intermediate passage area. Based on the classification and summary of the layout of existing subway functional parts, three different layout factors that affect the preference choice of standing passengers are proposed. Including the number of center pillars (single carriage has 4 and more than 4), the door area handle type (vertical bar and high bar), seat layout (N+N type and N+2 type). A total of 184 people were selected to participate in the investigation of the attitude of preference for standing position. By introducing the concept of the preference degree of the standing position, the preference degree of the passenger standing position under the condition of the differentiated layout was compared, and the differentiated layout was shown on the paper prototype. And use the multivariate ordered Logit model to analyze the data.The results show that the number of central pillars in a single carriage is greater than 4 and the high ring bar in the door area is a risk factor for the transition zone to obtain a higher degree of preference. When the number of mid-pillars is greater than 4 and the door area is a high ring bar, passengers will The preference of the transition zone has declined; the N+2 layout is a risk factor for higher preference in the door area. With the N+2 seat layout, the passenger’s preference for the door area has declined; in a single compartment The number of uprights is greater than 4, the high ring bar in the door area and the N+2 seat layout are the protective factors for a higher degree of preference in the middle aisle area. When the number of columns in a single carriage is more than 4 or the door area is a high bar or the seat layout is N +2, passengers' preference for the middle aisle area will increase. The data results confirm that the layout of the compartment facilities will affect the preferences of passengers for different standing areas. The number and placement of the columns will guide the path of passengers, and the grip comfort of the handrail facilities is also an important factor that affects passengers’ willingness to choose. While, the degree of influence of the transition zone and the intermediate channel zone is exactly the opposite.
