AI Technical Summary

Technical Problem

Existing traffic early warning systems are unable to quickly and accurately replan the optimal emergency guidance route based on real-time traffic congestion, and lack in-depth analysis of historical and environmental data, resulting in inaccurate predictions and unscientific emergency guidance.

Method used

The system collects historical congestion data, environmental data, and real-time traffic data through a data acquisition unit. It then uses a data processing unit to identify congestion-risk road sections and time periods, and combines graph theory algorithms to plan multiple alternative guidance routes. Finally, it selects the optimal emergency guidance route and uses a display module and a push module to provide detour suggestions to vehicles.

Benefits of technology

It improves the accuracy of congestion prediction, provides scientific and effective detour suggestions, alleviates traffic congestion, improves road traffic efficiency, and realizes the functions of real-time collection, analysis and guidance of traffic information.
