Visual analysis of route choice behaviour based on GPS trajectories

There are often multiple routes between regions. Many factors potentially affect driver´s route choice, such as expected time cost, length etc. In this work, we present a visual analysis system to explore driver´s route choice behaviour based on taxi GPS trajectory data. With interactive trajectory filtering, the system constructs feasible routes between regions of interest. Using a rank-based visualization, the attributes of multiple routes are explored and compared. Based on a statistical model, the system supports to verify trajectory-related factors´ impact on route choice behaviour. The effectiveness of the system is demonstrated by applying to real trajectory dataset.
