Our TOPO product family is the only radar system that can offer axle detection along with length and speed measurement. Its recording and classification functions – including an additional microphone for pinpointing the position of the engine block – open up new dimensions in traffic data capture. Our devices can be used on roads inside and outside of urban areas. They can be integrated in a standard reflector post or installed on various pole systems.
