ABSTRACT:
A barrier system which provides a new and unique approach to separating traffic and provides a safe, convenient and effective means of controlling traffic. Segmented continuous interlocking barriers embedded in the roadway rise out of the roadway to prevent head-on collisions between opposing lanes of traffic to aid in the prevention of serious accidents and loss of life on any undivided roadway on a suspension or truss bridge. All electro-mechanical mechanisms are controlled by PLC programmable controllers, automation software and a data processor control system link with mobile end-system wireless link compatibles in a multi-capability environment to perform the electro-mechanical tasks in altering traffic lane configurations. A set performance schedule is set up according to traffic flow by user in the alternating of its mechanical barrier devices in sequential order, with means from pneumatic air cylinders. The system is provided with a protective ground motion seismic sensor device in the safety circuits.
