Vehicle axle sensor

A roadway vehicle sensor includes a coextrusion having a linear conductive section and a linear non-conductive section forming a vehicle deformable closed housing. The linear conductive section has an inwardly projecting conductive plunger along the length thereof which is fused to wedge removal arms. The linear non-conductive section has a pair of inwardly projecting insulating wings having wing tips spaced apart a distance defining a plunger gap. The insulating wings also define a contact chamber into which the plunger protrudes only upon deformation of the vehicle deformable housing by a vehicle. Preferably, the vehicle deformable housing has a flat side on the exterior for engagement with a roadway surface. A contact assembly in the contact chamber has one or more flat conductive lane switch segment, each flat conductor lane switch segment having a width which avoids phantom switch closures.
