ABSTRACT:
An elastic strip with inside electrical contacts and trapezoidal geometry for the detection of the transit of vehicles includes a deformable body made of an elastomeric material with a central cavity for metal contact elements. About the central cavity are a pair of channels which operate through structural shape deformation during compression to minimize shear stress on the strip. The upper surface of the strip is provided with a protective longitudinal armor-like surface part, made of metal or other suitable material which comes in contact with the wheels of vehicles.
