3 Background Introduction Motorists driving the wrong way on divided roadways has been an area of concern for transportation agencies and the traveling public for over 50 years. Even though wrong-way crashes are infrequent, they are a serious problem because such crashes typically result in death or serious injury to the people involved (NTSB 2012)

4 ramps. To accomplish this, researchers undertook the following major efforts: • Assessment of data and findings from previous wrong-way driving studies to quantify crash characteristics, identify countermeasures, and assess the effectiveness of countermeasures; • Comprehensive review of the MUTCD regarding wrongway movement signing and markings at freeway ramps and non-signalized divided highway crossings; • Analysis of the effects of median width and traffic control devices upon wrong-way crashes on high-speed rural and urban divided highways using a multistate dataset developed under this research effort; • Evaluation of the effectiveness of LEDs within the border of WRONG WAY signs and red RFBs above and below WRONG WAY signs at freeway exit ramps; and • Development of proposed changes to the MUTCD based on the findings of the research.
