Abstract: Ride-hailing service (RHS) has become an important transportation mode in our daily life. Although many works have been proposed to improve RHS from different aspects, only few works focus on the selections of pick-up locations, where rider and driver meet and start a trip. In this paper, we present MPLRec , a data-driven pick-up location recommendation system that exploits riders’ specific mobility demands, e.g., destination, and historical experiences to meet riders’ travel requirements. MPLRec generates potential pick-up locations over the road network and characterizes them with rich features that describe a location from the riders’ perspective. We also build spatio-temporal indexes to organize potential pick-up locations and historical data for facilitating online recommending. When processing an online recommendation request, MPLRec derives candidate pick-up locations and investigates them with materialized features, which are computed from historical order and trajectory data while considering rider's mobility demands. Based on these features, a novel scoring function is used to derive the best pick-up location for each request. Moreover, we implement an RHS simulator to evaluate MPLRec using large-scale practical ride-hailing datasets. Extensive experiments and simulations demonstrate the effectiveness and efficiency of MPLRec , which can complete each request within 0.5 s and largely reduce the ride-hailing costs when compared to baseline methods.
