The invention relates to the technical field of traffic control, in particular to an intersection traffic control method and
system based on vulnerable group passage optimization. When the traffic light is in a
green light state, vehicles pass, pedestrians wait at the two sides of the
pedestrian path, the identification module obtains
human body characteristics and
modes of the pedestrians at the two sides of the path at the moment to identify whether vulnerable pedestrians exist or not, and if the vulnerable pedestrians exist, the identification module marks the vulnerable pedestrians as first vulnerable pedestrians and determines
vulnerability labels and levels of the vulnerable pedestrians; and the control module determines a
delay coefficient according to the
delay coefficient, and prolongs the duration of the traffic light in the
red light state next time according to the
delay coefficient, so that the first vulnerable
pedestrian has more passing duration. Besides, in order to avoid corresponding
traffic flow congestion caused by
red light delay, cloud and dynamic adjustment can be carried out on flow dredging of the original
traffic flow based on flow dredging compensation delay increment of the downstream intersection, a more humanized traffic environment can be constructed in an aging structure, and the method has remarkable
social benefits.
