In order to avoid pedestrian traffic accidents caused by distracted attention, the Korea Institute of Civil Engineering and Building Technology (KIET); KICT”) We have developed an intelligent pedestrian system that uses LED warning lights to alert drivers and pedestrians to pay attention to traffic safety. 

KICT researchers have designed the next generation pedestrian traffic accident prevention system, which integrates LED embedded pavement, thermal imaging cameras, electronic signs, and an application software. 

When the thermal imaging camera detects pedestrians approaching the sidewalk, it will activate the LED lights embedded on both sides of the sidewalk to alert pedestrians to incoming vehicles. According to KICT, the brightness level of the warning light is 220 cd/m2, which can be seen from a distance of about 50 meters. When the vehicle approaches the sidewalk, the electronic sign (Variable Message Board VMS) will flash to remind the driver again that pedestrians are crossing the road.

It is reported that this is a three-way warning system. When a car with a speed of 10km/h or faster approaches the sidewalk, the projector will project a warning image on the ground. At the same time, the auditory alarm system is activated, and the smartphone application alerts the user through vibration and sending warning notifications.

The research team tested the system on 1000 cars and reported that 83.4% of car drivers noticed pedestrians and slowed down. Researchers say that the system can also reduce the average speed of cars by nearly 20% when approaching sidewalks.

Dr. Jong Hoon Kim, the project leader of KICT, stated that they will continue to develop the warning system so that drivers can notice upcoming intersections through the navigation app and automatically slow down when dangerous situations are detected.
