The invention discloses a vehicle and traffic light two-way
information exchange controller. A traffic light intelligent module is connected with a vehicle-mounted intelligent module through a
wireless communication module, an input end and an output end of the traffic light intelligent module are respectively connected with a
central processing unit (CPU) module and a
signal switch module among traffic lights, an output end of the traffic light intelligent module is connected with an input end of a
driving circuit, and an output end of the
driving circuit is connected with input ends of the traffic lights. The vehicle and traffic light two-way
information exchange controller has the advantages that a traffic light
system is not controlled by a fixed program, the time for a
red light or a
green light in each direction can be determined by collected driving
direction information of each vehicle and the
traffic flow according to information transmitted from every adjacent crossing, and the traffic lights transmit the information collected at the crossing of the traffic lights to adjacent crossings, can collect
road condition information of every adjacent road, can transmit the
traffic flow information of every adjacent road to a driver in each vehicle, and can display the best running speed or the best
running time of each vehicle for passing the next crossing.
