• Abstract:
  Since 2003, the Texas Department of Transportation (TxDOT) has embarked on an aggressive campaign to install ; median barriers to prevent cross-median crashes on freeway facilities statewide. In the few years prior to 2003, ; virtually all fatalities on interstate facilities (96 percent) were the result of cross-median crashes. TxDOT used special ; safety funding to accelerate projects and decided to primarily implement high-tension cable/wire rope median barrier ; systems in lieu of concrete so that more roadway miles could be protected. ; This report documents the development of guidelines for use of cable barrier systems in Texas. The research team ; performed a comprehensive review of currently available guidance on cable barrier systems. The guidelines review ; included four broad categories: ;  guidance on barrier selection, ;  guidance on barrier design, ;  guidance on barrier placement, and ;  guidance on general system considerations. ; The development of guidelines for cable median barrier systems in Texas concentrated on existing information in state ; departments of transportation (DOT) design manuals and memorandums, manufacturer product manuals, and ; completed studies – including the results of the in-service performance evaluation in Texas. The development of ; consistent and practical guidelines for the use of cable barrier systems is necessary so that TxDOT design, operations ; and maintenance staff can make sound decisions. Since the use of cable barrier systems is still a relatively new practice ; in Texas, the guidance is timely because many districts continue to look for sites and funding for implementation. This ; report is written primarily to convey the cable barrier system guidelines.
