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.
