We built a taxi recommender system based on a whole week real GPS data, and simulated a virtual taxi to evaluate the performance of the recommender system. We found that the revenue of the virtual taxi drivers who used the recommender system were 99% better than other taxi drivers in weekday, and also got 96% better than other taxi drivers in weekend. We built a taxi recommender system by a real GPS data in another week, and simultaneously simulated a virtual taxi to evaluate the stability and performance of our recommender system. We found that the revenue is 94% better than other taxi drivers in weekday and 82% better than other taxi drivers in weekend. As a result, taxi drivers who use our taxi recommender system get more revenue than other taxi drivers which drive by their experience.
