Abstract
A linear roadway vehicle sensor for sensing vehicular traffic thereover includes a flexible carrier member comprising an elongated flat elastomeric member having upper and lower surfaces, a recess formed in the lower surface. The recess has a first top surface and a linear weight is distributed along the length of the flexible carrier. An adhesive secures the linear weight in the recess in said flexible carrier. The weight has a second top surface and a weight per unit length which is sufficient to maintain the sensor on said roadway and substantially immune to lifting from the roadway because of air flow effects and turbulence caused by vehicles, and one or more sensor grooves formed in the top surfaces and an elongated sensor in the one or more sensor grooves and between the elastomeric member and the linear weight means.
