AI Technical Summary

Technical Problem

Existing urban road traffic signal systems are prone to signal interruption, slow response, and traffic disorder during natural disasters, sudden power outages, or communication disruptions. Traditional emergency solutions are inefficient and cannot meet the real-time dispatching needs of high-density traffic in smart cities.

Method used

The system employs a laser hovering emergency flight traffic light system based on intelligent scheduling and multi-source perception. It includes a flight execution unit, a perception and acquisition unit, a command scheduling unit, and a laser display unit. By using drones to hover, it replaces ground traffic lights, achieving real-time data acquisition, path planning, and signal display. It has dynamic deployment capabilities and can independently control signal indication according to pre-stored rules when communication is interrupted.

Benefits of technology

It enables rapid replacement of traffic signals within seconds, ensuring the continuity and safety of traffic order, improving the system's fault tolerance and operational reliability, and enhancing the city's traffic management capabilities and emergency response efficiency in the event of an emergency.
