Siemens' sensor offers lane-wide cyclists detection

189 Siemens has introduced a microwave radar-based cycle detector called WiMag. The sensor is buried in the road surface and covers a 3m wide lane which the company said means that unlike loops, the cyclist does not have to pass directly over the sensor to be identified. It is secured in a 100mm diameter core-drilled hole using silicone sealant, has a minimum five-year battery life and transmits to repeaters at a distance of up to 30m. The sensor can now be used to detect the presence of bicycles, provide count information and enable traffic signal phasing to be based on actual cycle demand.
