Embodiment approach
[0060] The present invention also provides a method for using the system to realize the control of the green wave band of the main road traffic signal based on the Internet of Things. In one embodiment, the method comprises the steps of:
[0061] (1) The signal control center server determines the direction of the traffic signal green wave belt control through the traffic information obtained from the database server, and controls the sequence of intersections according to the signal in this direction, and sets the first group of two consecutive intersections to Set as the current control intersection group;
[0062] (2) The signal control center server obtains the vehicle (C 1 ) pass through the time information of the current control intersection group, and determine the vehicle speed VC of the vehicle passing through the current control intersection group according to the following formula 1 :
[0063] V C 1 = ...
