Method for acquiring taxi-hailing hot spot based on taxi GPS data

The invention discloses a method for acquiring a taxi-hailing hot spot based on taxi GPS data, and belongs to the field of intelligent traffic. The method comprises that: a taxi GPS record set in a period of time is acquired, and a record subset with occurrence of passenger getting on/off and empty taxi stoppage is selected from the record set; grids in which all GPS records in the record subset reside are confirmed, and number of times of occurrence of passenger getting on/off and empty taxi stoppage in each grid is acquired; hot spot grids are selected and spatially clustered; and taxi-hailing popularity of the hot spot grids is confirmed. With application of the method, searching of a surrounding empty taxi is facilitated for passengers, or the passengers are prompted to travel in other modes in case of no sufficient taxis so that travel time and cost of the passengers are saved, and thus operation efficiency of a taxi system and even the whole urban traffic system is enhanced.
