Toward a Highway Traffic Flow Monitoring System Based on Mobile Phone Signaling Data

With the rapid growth of the population, the resulting amount of pedestrian traffic puts greater pressure on the traffic management and travel services of cities. The original-destination analysis of residents' travel can effectively promote the optimization of urban regional traffic planning and the release of accurate traffic information. The rapid construction of the cellular network and the expansion of the personal smart phone, with which the user terminal interacts with the cellular network, generate a large amount of communication data, including additional time for the intelligent terminal to transmit the carrier base station. This paper proposes a mobile phone signaling-based user travel feature recognition and road network traffic monitoring system. This solution uses mobile phones as a probe to collect vehicle signaling data along the road to evaluate vehicle distribution and road traffic flow. It reflects the congestion status of the road, simultaneously analyzes the user's travel characteristics and regional distribution in the area through user trajectory, and dynamically evaluates the running status of urban road traffic.
