Traffic Sensors Are Equipped With Advanced Software Require A High Level Of Maintenance

 

Traffic Sensors

Traffic management, automatic incident detection, and data collecting all involve traffic sensors. To reduce congestion in major metropolitan areas, traffic sensors give standard data on traffic, speed, and area occupancy. Additionally, these sensors enable precise average flow speed measurement, allowing for the differentiation of various service levels, including crowded, congested, queued, and fluid. The effectiveness and capacity of transportation networks are increased by traffic sensors.

Traffic Sensor include inductive-loop detectors, magnetometers, video image processors, laser radar sensors, microwave radar sensors, ultrasonic sensors, passive infrared sensors, and passive acoustic sensors. These sensors are used for incident detection, traffic signal control, mainline control, and vehicle volume measurement.

Road traffic data is gathered using traffic sensors for signal control, and the gathered information is also provided to the Vehicle Information and Communication System Center (VICS Center). By taking the place of pushbuttons and detecting pedestrians crossing the street to prolong the length of the green light, pedestrian sensors offer security for pedestrians.

These sensors use the reflection of ultrasonic waves sent from ultrasonic transmitters/receivers mounted right above the road to detect the presence of a vehicle. By using a consistent sensory function, they are employed to measure traffic volume and occupancy rates.

The image-based vehicle sensor uses AI (deep learning)-based object detection technologies with a maximum measurement area of 30 metres to identify cars. This sensor is used for right turn sensing control, which involves detecting vehicles in right-turning lanes and optimally adjusting the 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 little traffic. In addition to measuring traffic congestion in the immediate vicinity of the vehicle.

The ultrasonic Doppler effect is used by these sensors. They use a change in frequency (the Doppler effect) in relation to the speed of the vehicle to detect vehicles moving in a specific direction. They are installed on low-traffic side roads and used for recall control to only turn the side road's traffic light green when a vehicle is spotted.

The optical beacon is a crucial piece of infrastructure for providing information to facilities for managing traffic on the road. It can assist relieve traffic congestion, lower CO2 emissions, and support the road vehicle cooperation system, which offers a variety of support for safe driving and regulates traffic flow using road-to-car communication between optical beacons and onboard gadgets.
