AVC(Automatic Vehicle Classification) can offer information of car types, such as speed, traffic volume and wheel track. It detect these informations as a real time and make a specific data files to transfer to central traffic center. It can be also deal with a various types of piezo and loop configurations. The signal detected from each cars are calculated as a classification and statistic information, and it also accumulated data and transmitted periodically to the traffic control center using specified protocol as daly, weekly. It also support all types of communication methods, such as TCP/IP, CDMA. It has self diagnostic ability. The status of systems, such as door open, fan&heater and conditions of each sensors.

Road Sensor NOVACOS - Piezo

The RSN-P is designed to be installed in the surface of the road for collecting traffic reports. The sensor is possible to be built under the configuration of the road and also designed to reduce the bending of the road, decrease the noise of the side lane and approaching vehicles signal. The specialized technology of NOVACOS makes it possible to install with least cutting so lesson the damage of the road and also reduce the use of the material for road suture.

RSN-P Performance

RSN-P Properties

RSN-P generates stated of high amplitude of piezoelectric and it used for classification of vehicles and counting the number of the vehicles

It also can eliminate all of, signal noises of the side lanes and all kind of road signal noises by approaching vehicles

We are provided distinguished technology and material for load sensing It is designed for easily set up and reduction of road cutting and minimized the use of the resin material

The sensor signal leveling is possible by maintaining the depth of the surface of road equally

Best products provided that pass the pre-test, before take out, with 100 percent reliability

We are fully provided for confidence and Optimization to Korea expressway condition and the durability of the client demand
