Ridesplitting is shaping young people's travel behavior: Evidence from comparative survey via ride-sourcing platform

摘要

To better understand the young people's sidesplitting behavior characteristics and behavioral impacts on the emerging ride-sourcing platform, we present a survey-based comparison of DiDi Hitch and DiDi Express Pool that provide ridesplitting services in Hangzhou, China. Hitch is a social carpooling platform that helps commuters share rides. Express Pool is a mobility network providing pooled rides as the sidesplitting option of Express. In this paper, we explore why ridesplitting is popular, which mode is the primary, and how sidesplitting affects young people's travel behavior. A total of 607 investigated responses were collected via the DiDi ride-sourcing platform. Based on the survey data, a variety of behavioral aspects were analyzed, including the trip purpose, temporal and spatial characteristics of trips, travel time/cost variation, and modal shift frequency. Behavioral impacts on modal shift were further analyzed in a binary logit framework. The findings show that Hitch and Express Pool have both similarities and differences. Hitch is intended for long trips, while Express Pool is mainly intended for short trips as a supplement of multimodal mobility. It also provides evidence for ridesplitting user identification and the market share loss of bus and taxi. Some suggestions are raised for discussions in future research.
