Exploring the Intermodal Relationship between Taxi and Subway in Beijing, China

الملخص EN

Taxi is an indispensable mode in the urban public transportation.

Although many studies have explored the travel patterns of taxi trips, few have combined taxi and subway to reveal their intermodal relationship.

To bridge the gap, this study utilized taxi’s trajectory data to investigate its relationship with subway.

Considering the multifaceted relationship between taxi and subway in operation, taxi trips are categorized into three types, namely, subway-competing, subway-extending, and subway-complementing taxi trips.

The characteristics of each type of taxi trips reflect the specialties and their interactions with subway.

The origin/destination distributions of taxi and subway trips are compared and analyzed.

Furthermore, the supply and demand of taxi within the buffer zone of each subway station are analyzed to reflect the difficulty of hailing taxis.

The negative binomial regression models are used to explore the relationship between taxi trips and subway ridership.

The results show that there is a significantly positive correlation between taxi trips and subway ridership.
