Embodiment Construction
[0056] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0057] like figure 1 As shown, a flow chart of a traffic control method provided by an embodiment of the present invention, the method includes:
[0058] Step 101: Obtain the traffic flow at the road intersection;
[0059] Step 102: Determine the delay time constraint condition of the road intersection according to the traffic flow of the road intersection, the delay time constraint condition at least includes the flow balance constraint condition of the road intersection;
[0060] Step 103: Based on the goal that the flow of the road intersection tends to be balanced, determine the capacity coefficient in the flow balance constraints;
[0061] Step 104: Based on the minimum delay time target of the road intersection, determine the cycle duration of the road intersection and the green light of each phase according to the traffic flow of the road inte...
