Embodiment 1

[0035] Embodiment 1: as figure 1 , a signal traffic system based on time compensation, including a dynamic traffic signal subsystem 10, an identification subsystem 20, an integral change subsystem 30 and a time compensation supply subsystem 40.

[0036] (1) Dynamic traffic signal subsystem 10

[0037] The dynamic traffic signal subsystem 10 mainly provides time compensation for pedestrians whose crossing civilization points reach the requirements through the dynamic setting of traffic lights. In order to realize the dynamic regulation of signal light, the signal light module 11 that dynamic traffic signal subsystem 10 is provided with includes fixed signal red light 111, dynamic signal red light 112 and fixed signal green light 113. The performance of time compensation mainly depends on the presence or absence and the duration of the dynamic signal red light 112. In addition, the dynamic traffic signal subsystem 10 also includes a time compensation instruction mobilization m...

Embodiment 2

[0081] Embodiment 2: a signal traffic management method based on time compensation, comprising the following steps:

[0082] ①Collect images and videos of pedestrian crossing behavior.

[0083] In a certain section of the road, there was a pedestrian who ran a red light and jaywalked across the street. The time for the pedestrian to run a red light was 19:00 in the evening. The road fixed shooting device 21 is mainly used to record the pedestrian's jaywalking behavior, and of course it can also be combined with other collection methods, such as drone shooting, vehicle-mounted camera capture, etc. Provide comparison between several collection methods and repeatedly confirm the pedestrian’s uncivilized street crossing behavior, which can make the system record the pedestrian’s uncivilized street crossing behavior more accurately. The main use of collecting images and videos of pedestrian crossing behavior is the recognition subsystem 20 A reference example of the road fixed pho...

Embodiment 3

[0111] Embodiment 3: Implementation effect of a signal traffic system based on time compensation

[0112] (1) Safety of pedestrians crossing the street

[0113] The civilized crossing of pedestrians reduces the possibility of vicious interactions between pedestrians and vehicles in the process of crossing the street, and greatly improves the safety of pedestrian crossing. Through simulation, the specific improvement of pedestrian crossing safety is as follows:

Abstract

The invention relates to the technical field of intelligent traffic, in particular to a signal traffic system based on time compensation. The system comprises an identification subsystem, a dynamic traffic signal subsystem, an integral change subsystem and a time compensation supply subsystem, and is characterized in that the identification subsystem is used for identifying behavior information, identity information and integral information of at least one target pedestrian, the integral change subsystem is used for changing the integral information according to the behavior information, the time compensation supply subsystem is configured to: receive request information of at least one target pedestrian, judge whether the integral information of the at least one target pedestrian reaches a preset integral limit value or not, and if yes, send the request information to a dynamic traffic signal subsystem, and the dynamic traffic signal subsystem is used for adjusting the distribution duration of the signal lamp according to the received request information. The invention provides a signal traffic system based on time compensation, so that the problem of unreasonable signal lamp distribution time in the existing signal traffic system is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a signal traffic system based on time compensation. Background technique [0002] In the process of vigorously promoting urbanization in China, the automobile industry has developed rapidly. The development of urbanization has intensified the supply pressure of transportation resources. The increasing number of vehicles and population makes the interaction between pedestrians and vehicles more frequent. These The interaction has also triggered more uncivilized traffic phenomena. [0003] In today's social background, the pace of life of urban residents is accelerating, their time pressure is increasing, and their demand for time is becoming more and more urgent, so when they cross the street as pedestrians, they are likely to cross the street in order to save time. road. Pedestrians jaywalking constantly affects the traffic order in the city, threatens the sa...
