A receiver/decoder is located remotely from the transmitter for receiving the radiofrequency signal from the transmitter, and a camera is positioned to photograph persons and/or vehicles within a predetermined area adjacent to the traffic sign during the period of time that a signal is received by the receiver/decoder.

Abstract: An improved roadway sign comprising a light retroreflective indicia region and colored retroreflective background region is provided. The retroreflective properties of the regions are selected such that the ratio of the retroreflective brightness of the indicia to that of the background is substantially larger at observation locations within the legibility zone for the sign, than the ratio is at observation locations outside the legibility zone. The sign is conspicuous by virtue of the bright retroreflection and distinctive color of the background outside the legibility zone, yet is legible because of the increased contrast ratio of the indicia to the background in the legibility zone.

Abstract: A slalom gate which has a lower support member adapted to be inserted into the snow. There is a retractable anchoring member mounted in the support member, in a manner that downward deflection of the post about a lower pivoting connecting portion pulls the anchor member upwardly to cause it to expand outwardly into the snow, thus resisting retraction of the support member from the snow. When the gate returns to its upright position, the anchoring member retracts so that the gate can more easily be removed from the snow.

Abstract: Support structures for highway signs and barricades include collapsible assemblies which cause the structure, upon impact by a vehicle, to rotate away from the impact without flying apart. The collapsible assemblies utilize a connector fixture to couple a first member to a second member. The connector fixture includes a pivot pin which provides an axis of rotation for the second member and shear pins which hold the second member in a fixed orientation until the application to the second member of an impact. The impact fractures one of the shear pins and the second member rotates about the pivot pin away from the impact. Single post and multiple post support structures are disclosed. A support structure having two vertical members collapses to a flattened position when struck from any direction. The vehicle passes over the flattened support structure. In an alternate embodiment, the support structure rotates upward upon impact and passes over the vehicle.
