Research on Targeted Release Technology of Dynamic Traffic Information Based on Mobile Phone Signaling Data

The timely release of dynamic traffic information is of great significance to ensure smooth road traffic. In order to send the dynamic traffic information to the travelers within the affected range in a timely and accurate manner, this paper proposes a key tracking algorithm based on cell phone signaling data. The algorithm contains steps such as network calibration and sequence extraction, sequence matching to the road network, accompanying roads culling and determining whether it is within the target range. The field test proves that the algorithm can accurately identify the travelers within the affected range.
