Traffic Management Solutions Traffic / pedestrian 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 / pedestrian sensors (image system)
Traffic image sensors can be placed to measure an area within 30 meters of a stop sign. These sensors can be used, among other things, to detect a vehicle in the right-turning lane, make the optimal changes to the length of time the right-turning arrow remains green, and turn the traffic light for a side road green only when a vehicle is detected on a side road with low traffic volume.
Pedestrian image sensors, on the other hand, ensure the safety of pedestrians crossing the road by extending the length of time the light for pedestrians remains green when there are pedestrians on the pedestrian crossing.
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.
Traffic sensors (far-infrared type)
These sensors use far-infrared rays to detect vehicles. Compared with active sensors such as ultrasonic waves and near infrared waves, the use of passive sensors that detect far-infrared waves emitted from an object results in a significant reduction in power consumption. This enables power supply by means of solar batteries and the use of wireless transmission, which means the sensors can be installed in various locations and used for various purposes.
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.
