Traffic system for predicting and providing traffic signal switching timing

A traffic system for predicting a traffic signal switching timing, the traffic system comprising:

• a camera sensor having a camera identification code (CID), the camera sensor comprising:
• a) a camera for capturing images of traffic signal lights along a traffic lane and the moving objects on the traffic lane;
• b) a CPU for running computer programs for analyzing the images of the traffic signal lights and the moving objects to learn traffic signal switching timing, wherein the traffic signal switching timing includes time stamps when traffic signal changes from green to yellow, a yellow lighting time being a duration time of a yellow light, a red lighting time being a duration time of a red light and a green lighting time being a duration time of a green light of each the traffic signal lights;
• c) a sound sensor for obtaining sound signals originated from the moving objects;
• and
• d) a communication interface for sending and receiving data associated with the traffic signal switching timing with the camera identification code (CID) to/from other camera sensors;
• and
• a server for providing traffic information including the traffic signal switching timing to drivers of the moving objects, the sever being arranged to receive and sends the data to/from the camera sensor.
