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 16):
The road traffic control system of  claim 15 , wherein the total delay time is 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 all pedestrians at the crossroad, wherein:\n the delay time for motor vehicles in the road flow direction being equal to a sum of vehicle delay times for motor vehicles on all branches, wherein a vehicle delay time for motor vehicles on each branch is equal to a product of an average delay time for each motor vehicle on the respective branch and an instantaneous vehicle flow of the respective branch in the road flow direction; and the average delay time for each motor vehicle on the respective branch is equal to a sum of an average signal delay time of the respective branch in the road flow direction and an average motor vehicle delay time caused by a conflicting area between motor vehicles and pedestrians; the delay time for pedestrians at all non-crossroad street crossings in the road flow direction being equal to a sum of signal delay times of the street crossings, wherein a signal delay time of each street crossing is equal to a signal delay time of the respective street crossing multiplied by an instantaneous pedestrian flow of the respective street crossing; and the crossing delay time for all pedestrians at the crossroad being equal to a product of a pedestrian flow at the crossroad and an average pedestrian delay time at the crossroad, wherein the average pedestrian delay time at the crossroad is equal to a sum of pedestrian delay times caused by conflicting areas between motor vehicles and pedestrians on all branches plus an average signal delay time for each pedestrian at the crossroad; wherein traffic light timing for pedestrians and non-motor vehicles and traffic light timing for motor vehicles are determined according to a minimum value of the total delay time.
