SEISMIC DETECTION OF MOTOR VEHICLES
The technical feasibility of detecting the approach of motor vehicles by seismic means was determined by the recording and analysis of road vibration, and verified by the construction of a seismic switch which was reliably triggered at a distance of 50 metres (164 ft) along the pavement by vehicles travelling at 50 km/h (30 mph).
