traffic lights

There is a common problem in the use the traffic lights in the urban road. When the driver driving his or her saloon car, if there is a truck or bus in front, therefore,the driver cannot see the traffic lights, which may cause the violation of traffic rules and the rear-end accidents. This design features in the installation of a small traffic signal lights in front of three light poes, to sense the change of the traffic lights through radio signals. This design is quite helpful when the view of the driver was blocked by the truck or bus. It helps the driver to know the traffic light, thus avoiding possible accidents.
