"Stop at a red light, go at a green light" is a well-trodden safety common sense, but there are still a lot of people put the lights aside, regardless of their own safety to run the red light, was joked as "gather enough people can walk, and has nothing to do with the traffic lights" "Chinese style road".Recently, in order to assist the traffic police to manage a motor vehicle to comity zebra crossing phenomenon, improve the traffic participants civilization quality, the first set of "the pedestrian red light capture system" in tongzhou district, town, LED display, with its unique display advantage "stand guard" traffic intersection, automatically capture and "live" red light traveller, has played a good warning role.

A powered pedestrians running red lights, LED display screen capture system Specializes in violations: the pedestrian red light capture system is no mystery, had earlier in shijiazhuang, shandong, jiangsu and other places to start pilot, mainly composed of a number of large Angle capture cameras, voice prompt system and LED display screen, if pedestrians, non-motor vehicle owners do not obey the traffic rules, camera recorded the whole process.Red light condition, the pedestrian across the waiting area into the early warning system and through the voice prompt, "do not cross the line" if pedestrians do not listen to discourage determined new lights, the system will enter the recognition capture zone, to obtain evidence, pedestrian violation and will capture images and video process in LED display screen, the exposure of the equipment.It may be that when a pedestrian runs a red light and is secretly pleased, he inadvertently raises his head and finds that his behavior of running a red light has been magnified by the LED screen for scrolling broadcast, and the resulting sense of shame inevitably makes the public pay more attention to his words and deeds.

As the system continues to upgrade, in addition to being able to capture pedestrians who run red lights, car owners who honk their horns at random will also be shown on the screen.Shenzhen yantian district is the first application of the sonar snapshot "equipment, through the use of sound source localization based on sonar array detection, video detection technology, can be in before and after the three lanes within 50 meters of the motor vehicle within the scope of illegal behavior in real-time acquisition, once has the illegal sound, the vehicle is known, the license plate number will be displayed on the LED screen.In this way, real-time detection, high-precision positioning and automatic investigation of honking vehicles in specific areas can be realized, and the horn can not only be "heard" but also "seen".

Second, technology upgrade highlight shows advantages: the pedestrian red light capture system is another innovative applications of LED display, compared with the traditional LCD, DLP, LED display can not only are more likely to achieve higher precision and better display color reducibility, and dustproof, waterproof properties is good, especially suitable for complex traffic environment.In addition, with the continuous progress of technology, small-space LED displays have also made breakthroughs in outdoor applications, which is more conducive to the qualitative improvement of the screen display effect of the system.

LED display in addition to the outstanding advantages, but also with facial recognition technology, video processing technology, combined with new technologies such as application of beamformer, after extraction and recognition of face in real-time, automatic face data storage through a red light, and through the real-time search, combined with the large data operation, find out the same person whether to have multiple red light behavior, by means of data docking, to verify the identity of the illegal personnel after penalties on traffic offenders.

Wisdom city drive LED display blossom everywhere: in wisdom city construction, the demand of urban rail transit construction to promote, LED display in the field of intelligent transportation shows hot, market share of the growing, from outdoor traffic-induced screen, bus intelligent display screen to indoor traffic monitoring platform, and then to major cities now have favored the pedestrian red light capture system, LED display has proliferated in the field of intelligent transportation, everywhere it figure.

In addition, with the maturity of VR, AR and other technologies, LED display combined with it will become a future trend, bringing more convenient applications for traffic command.For example, in the United Kingdom, there is a new intelligent pedestrian crossing system - intelligent crossing ground display system.The system will dynamically guide you across the road in real time using traffic signs and colors based on road conditions.When pedestrians cross the road, a pattern will appear on the ground through the LED screen, showing the zebra crossing, and a warning sign will appear in time to warn drivers and cyclists to stop.When a pedestrian crosses the road and the system confirms there are no other pedestrians, the zebra crossing disappears and the driver can proceed.The advent of this system, in the current phubbing, mobile phone is the biggest welfare.

The application of LED display screen in the field of transportation not only saves the social management cost, but also provides the premise guarantee for traffic safety. At the same time, it also brings great convenience for citizens‘ travel.At present, leading enterprises in the industry have made efforts in the field of intelligent transportation, and launched numerous related products. As the carrier of communication, LED display screen is believed to be a better one in the intelligent transportation display market.
