Signal control method and system for pedestrian detection

Abstract

The invention belongs to the technical field of pedestrian traffic signal control and discloses a signal control method and system for pedestrian detection. The method comprises the steps that by checking the size of the people stream of a pedestrian waiting area, the pedestrian crossing phase time is automatically distributed; according to the number of detected existing passing pedestrians on zebra stripes, the red lamp time for conflict phases of conflict motor vehicles is prolonged; when it is detected that no pedestrians exist on the waiting area and the zebra stripes, no pedestrian phases are executed or pedestrian phases are reduced; when it is detected that a large number of people continuously pass through the waiting area and the zebra stripes and it is detected by a vehicle detector that no motor vehicle passes or few motor vehicles pass, the phase time for the motor vehicles is shortened, or the phases of the motor vehicles are deducted. According to the method, based on pedestrian detection data, the traffic pedestrian crossing phase time distribution or arrival mode are reasonably adjusted; the optimal time for pedestrian crossing is dynamically adjusted, so that thecrossing time for a crowd of pedestrians is sufficient and reasonable; when no pedestrian crossing demand exists, the pedestrian crossing phases are reduced, and the maximum application efficiency ofa road is achieved.

Description

technical field [0001] The invention belongs to the technical field of pedestrian traffic signal control, in particular to a signal control method and control system for pedestrian detection. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] According to a study in the United States, human beings spend about 1.6 billion hours each year waiting for traffic lights to turn green, which translates into an economic cost of 2.6 billion U.S. dollars...   [0004] At present, major domestic manufacturers basically use vehicle detection as the basic data, and adjust the signal light time in real time according to the current traffic flow, so that vehicles can quickly pass through the intersection, reducing the number of parking times and parking waiting time, so as to achieve the purpose of alleviating congestion. For pedestrians, basically no control method is adopted. Regardless of whether there are pedestri...

Problems solved by technology

[0013] In the past, signal control was based on the control strategy under the condition of motor vehicle detection. At present, there is no signal control strategy based on pedestrian detection; it is very difficult to combine pedestrian detection technology and control strategy to form a pedestrian control method and system.
