Taxi, as an important supplement of urban public transport, plays an important role in resident daily traffic. However, because of the unbalanced spatial and temporal distribution of the potential passengers, high no-load rate and unhealthy competition keep releasing negative impacts on taxi business. With the development of ITS (intelligent transport system) technology, more and more attempts have been made to study approaches of seeking taxi passengers, while neglecting the analysis of high profitable seeking strategy. Based on mathematical statistics and geo-statistics, we propose a novel spatial and temporal analysis method based on an evaluation index, which takes the combination of income per unit time in the load state and the time for seeking passengers in the adjacent no-load state. We investigated the Shenzhen's taxi data set, which contained 13 798 taxis GPS trajectories during a week from April 18 to April 24, 2011 to conduct a comprehensive analysis on the characteristics of taxi operation and the spatial and temporal distribution of people's daily traffic. Our study indicates that the designed method yields a better reflection on the distribution of high profitable passengers, providing a new perspective for the efficient operation of the taxi.
