A traffic sensor for dispostion across a lane or lanes of a roadway includes a pliable strip within which is housed a flexible carrier which in turn supports electrical sensors and coaxial cables. The components are in circuit with a roadside located recording device. Vehicle imparted loads applied to the strip and carrier are counteracted by an inelastic member extending lengthwise of the strip to prevent erroneous electrical impulses. The inelastic is embodied in strands of material embedded in the carrier. Fastener elements extend through the strip for insertion into the roadway for strip retention.
