Fixed Installation Post Traffiphot S Piezo Sensor
This system from Peek Traffic, works on Piezo Sensors in the road. The strips are a known distance apart, and the time between compression's is measured to give the resulting speed of the vehicle. The system takes two readings on a two axle vehicle and uses the average time for compression's to calculate the resulting speed. Radar Detectors are useless with this type of camera. The picture above shows the strips in the road and in this case covers both lanes on the duel carriageway. |
