Guardian / Warning board


With the continuous expansion of modern cities, traffic problems have increasingly become a key factor restricting the development of cities. The rules and order of public transportation are very important for the smooth operation and safety of traffic. The mobile “warning traffic light” installed on the bus serves as an effective supplement to the existing fixed traffic light indication system, which solves potential traffic hazards in an all-round way, greatly improving traffic safety and reducing traffic accidents. It has alleviated traffic pressure and guaranteed people's lives.
