Track-oriented Urban Traffic Analysis based on Network Accessibility

Longfei Wang, Hong Chen, Yang Li

Abstract


Accessibility is a fundamental concept in traffic analysis. In this paper, we present a track-oriented traffic analysis method based on urban network accessibility. Firstly, a direct access relation network model is constructed to clarify the overall thought of this method, which can guide the whole procedure of track analysis. Then, two track analysis algorithms on track separation and track restoration are established to handle abnormal data acquisition. Experiment results indicate that the method can obtain detailed vehicle travelling tracks, through which rich and accurate traffic operation status information can be generated.

Keywords
