Abstract:

Due to the lack of bus operating data, some scholars put forward a method, which uses the orthogonal transfer information between different bus routes, to derive the boarding station information of bus passengers. However, a lot of the bus single trips lack the orthogonal transfer information in practical applications, which lead to the difficulty in deriving the boarding station information of bus passengers. To solve this issue, based on the existing research, this paper put forward a method for deriving the boarding station information of bus passengers based on the comprehensive transfer information mined from IC card data. This method uses the comprehensive transfer information between the subways and buses information mined from the IC card data to confirm the driving direction of buses, and then, divide the passengers of the same single trip into groups. These groups would match the corresponding boarding stations more accurately. We fully take use of the orthogonal transfer information and non-orthogonal transfer information between different bus routes and the transfer information between subways and buses to recognize the fiducial groups and their boarding station information, then, we use the minimum error rule to derive the pending groups′ boarding stations. Using the transfer information to confirm the driving direction could enlarge existing research on how to determine a single trip's driving direction, which makes the method of driving the boarding station information of bus passengers more complete and scientific. In the end, through example analysis, this study greatly increases the number of fiducial groups. This method has a higher reliability and accuracy compared to the method which only uses the orthogonal transfer information between different bus routes to derive the boarding station information of bus passengers. In this study, we use the transfer information to confirm the driving direction of some single trips with the absence of the location data. In addition, we use the transfer information mined from three transfer approaches to derive the boarding station information of bus passengers as well as put forward a series of constraint rules to make the result more accurate and feasible, which are considered to be the most significant innovation and contribution. Deriving the boarding station information of bus passengers is the up-front work in getting the bus passengers' demands and the bus service ability data, which has a guiding significance to urban planning.
