Two major tasks were completed in the second phase of this project. Task 1 was to organize a national wrong?way driving (WWD) summit which was held in Edwardsville, Illinois, on July 18 and 19, 2013. The conference proceedings were published by the Illinois Center for Transportation (ICT) in 2014. An executive summary on the findings and ideas from the summit are included in this report. A survey was conducted during the summit to collect data on current practices regarding WWD countermeasures by various state agencies. Chapter 2 of this report contains details about the summit and survey. Task 2 was to develop guidelines for reducing WWD on freeways. The guidelines were published by ICT in 2014 as a separate report. These guidelines were developed based on the current guidelines and policies related to WWD prevention in the 2011 AASHTO Green Book, the 2009 Manual on Uniform Traffic Control Devices (MUTCD), and best practices from other states. The guidelines consist of four chapters: introduction, traffic control devices, geometric designs, and advanced technologies. A 4-hour training course was then developed based on the guidelines. A pilot training was conducted on March 26, 2015, in Springfield, Illinois. The participants’ comments and evaluation results are included in this report. The final training materials, consisting of instructor’s notes and a student handbook, are also submitted with this final report. Chapter 3 of this report contains detailed information on the participants’ evaluation results of the training material. Another subtask was to identify and develop methodology to evaluate implemented WWD strategies. The additional 2-year after period crash data (2012—2013) were collected and used to conduct a simple before-and-after study. The preliminary results showed that the number of WWD crashes had declined after the countermeasures were put into place. Because most countermeasures were implemented in early 2014, additional after-implementation crash data are recommended to be collected so that a more comprehensive evaluation of the countermeasures can be conducted. The preliminary evaluation results are contained in Chapter 4. (Author/publisher)
