Abstract

Taxi trip-sharing is of great significance to improve the overall traffic efficiency of the city. The calculation of the matching possibility between any two taxi trips in a given time range is large, so it is difficult to meet the application needs of the whole urban space. This paper proposed a fast filtering strategy based on time, distance and direction constraints. It applied the strategy to the trip-sharing matching method which was based on graph. The results verified by the New York city taxi data set, show that the proposed filtering strategy can greatly reduce the matching time without affecting the effect of trip-sharing(the matching time of a single trip is reduced by about 82%). Based on the GPS trajectory data of 8 531 taxis in Qingdao on March 15th(Wednesday) and March 18th(Saturday) during 2017, this paper made an empirical analysis. It shows that when the delay threshold is set at 5 min, the number of shared trips in the city on workdays can reach 45% of the total trips, the total travel time can be saved close to 5 000 hours, and the total distance can be saved 80 000 km. The results of Saturday and Wednesday are very close. The number of trips during the morning rush hour from 6: 00 to 9: 00 is relatively small and the spatial distribution is relatively scattered. Therefore, the proportion of shared trips, the total saved time and saved distance are the least compared to other period. The benefit of trip-sharing during this period is the smallest.
