The invention relates to a traffic control method and
system based on an intersection group.The method comprises the steps that 1, 360-degree panoramic video of intersections is dynamically collected in real time through an intelligent
robot, an intersection
operation model is established according to video data, and traffic characteristics of the intersection group are analyzed according to the intersection
operation model; 2, intersection index evaluation and online
simulation analysis are conducted according to the traffic characteristics, and the traffic operation state of the intersection group is identified; 3,
supersaturation state intersection
signal timing control scheme optimization is conducted on critical paths of a
supersaturation state intersection group, and a
supersaturation state intersection group
traffic signal control strategy is adjusted; 4, the adjusted intersection group
traffic signal control strategy is operated, and steady-state operation of an intersection
control signal timing optimization scheme and linkage command of the intelligent
robot are achieved.By means of the traffic control method and
system based on the intersection group,
traffic efficiency and service level of intersection
single point control can be improved, and therefore the operation efficiency of an urban
traffic system is greatly improved, and urban traffic
jams are relieved.
