A roadway sensor(10) is comprised of an elastomeric carrier having conductive properties. A sensor passage (11) formed in the carrier and a plurality of polytetrafluorethylene coated wire conductors (15') tightly fill the sensor passage (11). Signal output terminals connected to said carrier and said plurality of wires. The coating on said wire is selected from FEP or TFE polytetrafluorethylene. In a preferrred embodiment, the passage (11) is waterproof and in another embodiment, the sensor passage (11) has walls and means on the walls for preventing moisture from affecting signals induced in the coated wire conductors (15'). |
