Efforts to Reduce Wrong-Way Driving: A Case Study in San Antonio, Texas

In response to several severe wrong-way driving (WWD) crashes and a perceived increase in area-wide WWD activity, San Antonio transportation and enforcement agencies formed a task force in the spring of 2011 to discuss the issue and identify means to address the problem. The task force became a forum for agencies to discuss means of combatting WWD and led to a number of efficiency improvements in how quickly local agencies were able to respond to WWD events and how consistently those events were documented for later review. In addition, several forms of WWD signing improvement countermeasures were applied to US Highway 281, the freeway corridor in San Antonio most frequently experiencing WWD events. To date, the signing countermeasures have resulted in a reduction in WWD activity in the test corridor.
