The increased availability of large-scale trajectory data provides rich information for the
study of urban dynamics. For example, New York City Taxi 8 Limousine Commission
regularly releases source/destination information of taxi trips, where 173 million taxi trips
released for Year 2013 [29]. Such a big dataset provides us potential new perspectives to
address the traditional traffic problems. In this article, we study the travel time estimation

The increased availability of large-scale trajectory data provides rich information for the study of urban dynamics. For example, New York City Taxi 8 Limousine Commission regularly releases source/destination information of taxi trips, where 173 million taxi trips released for Year 2013 [29]. Such a big dataset provides us potential new perspectives to address the traditional traffic problems. In this article, we study the travel time estimation problem. Instead of following the traditional route-based travel time estimation, we propose to simply use a large amount of taxi trips without using the intermediate trajectory points to estimate the travel time between source and destination. Our experiments show very promising results. The proposed big-data-driven approach significantly outperforms both state-of-the-art route-based method and online map services. Our study indicates that novel simple approaches could be empowered by big data and these approaches could serve as new baselines for some traditional computational problems.
