Abstract:Even though wrong way driving (WWD) crashes on
controlled-access highways are infrequent (less than
1 percent of all traffic crashes in Texas), they result in
severe injuries and fatalities, and continue to occur
despite more than 50 years of research and
countermeasure implementation. Questions
remained about which countermeasures actually
catch the attention of wrong way drivers and are
effective at getting them to self-correct before
reaching the main lanes, especially those drivers that
are driving under the influence of alcohol. In addition,
recent implementations of WWD countermeasures
and mitigation methods in several locations in Texas
provided the opportunity to assess the effectiveness
of these tools in actual operational environments.
The Texas Department of Transportation (TxDOT)
also posts wrong way driver warning messages on
dynamic message signs (DMSs); however, no
guidance existed about the design of these types of
messages
