Identify methods, physical improvements, and technologies to mitigate wrong way driving that looks holistically at an agency's entire roadway system.
IV creates a virtual world in which to model projects accurately in 3D, then render videos and images as well as immersive visualizations to create interactive simulation products. IV models are built from existing and proposed data, including agency design files (i.e., a Microstation roadway surface), while a game engine powers real-time presentation. When optimized with adjacent infrastructure to produce performance simulation, touch screen kiosks and virtual reality (VR) applications can provide a virtual helicopter tour over a proposed project, for instance.
Project NEON, Nevada's largest and most expensive public works project ever, was the catalyst for the initiative. IV helped convey complex planning and design scenarios to the public while helping project development personnel identify and resolve design and construction challenges, such as site impacts and right of way, geometric, and line-of-sight issues. IV products allowed the traveling public, homeowners, and businesses to see the potential impact of the project on their interests, while addressing their concerns and those of regulatory agencies about safety and environmental impact. As a result, IV vastly enhanced interagency coordination, regulatory review, and approval.
IV supplies much more freedom of camera movement than typical state-of-the-practice project visualizations, which provide views from specific angles. That enables non-outreach products like technical clarity visuals, graphics for related legal cases, landscaping details, and more. While conventional visualizations render various images for delivery via video files from which models are constructed for a given purpose, rapid, real time rendering through IV’s game engine technology eliminates the need to remodel, bringing its overall cost in line with traditional 3D visualization.
Research by the AAA Foundation for Traffic Safety found that from 2010 to 2018 an average of 432 people were killed each year due to wrong way driving crashes on controlled-access highways.  This analysis shows the increased incidence from previously reported data that had indicated an annual average of 360 fatalities from 2004 to 2009.  Of further concern, the annual number of fatalities over the more recent time period generally exhibits an upward trend.
Many transportation agencies currently implement wrong way driver detection and deterrence tools and practices, but the variety of potential tools and practices vary, are often expensive, and are, in some cases, adopted as “spot treatments," typically at the corridor scale. Recent research has found that risk factors for wrong way driving do not limit themselves to high-volume corridors. For example, the risk of being a wrong way driver increases with blood alcohol content and vehicle age, and for drivers with suspended or revoked licenses and those ages 70 and over. Further, wrong way driving is not limited to divided highways or freeways and can also be addressed along arterials where wrong way driving crashes occur more frequently, though with a lower risk of fatality.
The AASHTO Innovation Initiative revisits wrong way driving—first examined under
Wrong Way Driver Detection Systems—by applying a systemic approach to detection and deterrence that looks holistically at an agency's entire roadway system. A Systemic Approach to Wrong Way Driving Safety will identify methods, physical improvements, and technologies to mitigate wrong way driving as an agency objective that integrates into existing approaches and programs for safety. Recent agency experience has shown a range of proven and emerging countermeasures are effective, depending on roadway characteristics such as interchange type, as well as demographic and land use factors. Many of these treatments are low-cost countermeasures, and readily implemented without substantial investment in technology, although individual agencies would need to evaluate the cost components.
A systemic approach to wrong way driving improves safety. Benefits include a reduction in wrong way driving events and a lower risk that a wrong way driving event will result in a crash.
Depending on the countermeasure deployed, safety benefits may include:
