Traffic Management Solutions Traffic sensors
Information Supply in Real Time
Traffic sensors are used to collect road traffic information for signal control, and the data collected is also supplied to the Vehicle Information and Communication System Center (VICS Center).
Pedestrian sensors provide security for pedestrians by replacing pushbuttons and sensing pedestrians crossing the street to extend the time of green light.
Traffic Sensors (ultrasonic type)
These sensors detect the presence of a vehicle using the reflection of ultrasonic waves transmitted from ultrasonic transmitters/receivers installed directly above the road. They are used for the purpose of measuring traffic volume and occupancy rates by means of a stable sensory function.
Traffic sensors (image system)
The image-based vehicle sensor has a maximum measuring area of 30 meters, and uses AI (deep learning)-based object detection technologies to detect vehicles.
In addition to measuring traffic congestion in the immediate vicinity of the vehicle, this sensor is used for right turn sensing control, which involves detecting vehicles in right-turning lanes and optimally changing the amount of time for green right turn arrows based on whether vehicles are detected, and recall control, which only turns traffic lights on subsidiary roads green when detecting vehicles on subsidiary roads with minimal traffic.
Traffic Sensors (Doppler type)
These sensors use the ultrasonic Doppler effect. They detect vehicles travelling in a particular direction using a change in frequency (the Doppler effect) according to the speed of the vehicle.
They are installed on side roads with low traffic volume, and are used for recall control to change the traffic light on the side road to green only when a vehicle is detected.
The optical beacon is a key infrastructure for supplying information to road traffic facilities.
It supports the road vehicle cooperation system (a system that provides various support for safe driving and controls traffic flow by means of road-to-vehicle communication between optical beacons and onboard devices), can alleviate traffic congestion and help reduce road traffic accidents and CO2 emissions.
