Study On Transfer Walking Time Law Of Transfer Passengers In Urban Rail Transit

With the intensification and improvement of my country’s urban rail transit network,the transfer activities of passengers are also common,and the transfer process is the main component of the transfer activities.For transfer passengers,the travel time during the transfer process is an important factor that leads passengers to choose the transfer route;as a rail transit management operator,the study of transfer travel time has theoretical reference for the reasonable connection of train timetables.Moreover,the transfer travel time is an important indicator to reduce the transfer time and improve the transfer efficiency of the transfer station.In addition,the mastery of the transfer travel time rule can not only be used as the basis for the later reconstruction of the transfer station,but also for the new subway.The transfer channel and facility layout provide a theoretical basis.At present,most of the research on the influencing factors of transfer travel time focuses on transfer distance,ignoring the influence of other factors on travel time,such as the status attributes of passengers and the influence of transfer environment.This paper comprehensively considers the influence of transfer travel distance,passengers’ individual attributes and state attributes,and transfer environment on the transfer travel time,and further supplements and improves the relevant research system of transfer travel time,mainly including the following researches content.First of all,the travel distance and travel speed of passengers are the basic parameters that determine the travel time.The influencing factors are analyzed from these two aspects,and the transfer streamline formed by the spatial layout of the transfer station and the transfer mode is discussed from the macro perspective.It is an important factor affecting the transfer distance.The individual attributes and state characteristics of passengers and the transfer environment are the main factors affecting the walking speed of passengers.Then,the general situation of Chengdu rail transit transfer station is analyzed,and the influencing factors of transfer travel time are subdivided in order to explore the influence of each influencing factor on passenger transfer travel time.1872 pieces of travel time data corresponding to each influencing factor were collected and sorted,the importance of each influencing factor was sorted by random forest algorithm,and the influencing factor when the cumulative weight was greater than 0.85 was extracted as the main influencing factor and analyzed.Finally,the simulation analysis is carried out on the extracted factors influencing the congestion degree and pedestrians’ companionship during the transfer process.By inputting different passenger arrivals,comparing and analyzing the output average transfer travel time and passenger flow density map,it is concluded that the degree of crowding in the transfer process has a significant impact on the transfer travel time.And put forward corresponding improvement suggestions for the organization of passenger flow during peak hours at the Cultural Palace Station.In addition,the simulation results show that the larger the ratio of pedestrians is,the longer the average transfer time of passengers.Therefore,it is suggested that the transfer station with a large proportion of leisure and entertainment as the travel purpose should do a good job in the corresponding passenger flow organization.
