Abstract:
A system includes a video traffic information analysis module configured to acquire a traffic condition parameter of a road network from video traffic information; a traffic condition prediction module configured to predict a traffic condition in a future period of time according to the traffic condition parameter to obtain a traffic condition prediction result; an actual traffic condition assessment module configured to assess an actual traffic condition based on the traffic condition parameter and according to a traffic condition evaluation model to obtain an actual traffic condition assessment result; and a traffic control decision module configured to determine a control scheme for a controllable traffic element using an optimization algorithm according to the traffic condition prediction result and the actual traffic condition assessment result. Traffic conflicts between motor vehicles, pedestrians and non-motor vehicles at intersections in a road network are reduced, thus effectively alleviating traffic congestion at the intersections.

Claim (Index 13):
The road traffic control system of  claim 10 , wherein a linear objective function used in the linear planning method is a total delay time in a road flow direction of each road section being equal to a sum of a delay time for motor vehicles in the road flow direction, a delay time for pedestrians at all non-crossroad street crossings in the road flow direction, and a crossing delay time for pedestrians at all crossroads, wherein:\n the delay time for motor vehicles in the road flow direction is equal to a sum of delay times for motor vehicles on all branches leading to the road flow direction, and the delay time for motor vehicles on branches is equal to a product of an average vehicle delay time for the motor vehicles on branches and an instantaneous vehicle flow in the direction, a delay time for pedestrians at all non-crossroad street crossings in the road flow direction is equal to a product of a sum of instantaneous flows of all street crossings in the flow direction of the road section and an average crossing delay time for pedestrians at non-crossroads, a crossing delay time for pedestrians at all crossroads is equal to a product of a sum of pedestrian crossing flows at crossroads of all branches in the road flow direction and an average delay time for pedestrians at the crossroads, and the control scheme is determined by calculating a minimum value of the linear objective function.
