ODOT to Enhance Wrong Way Signage
BOWLING GREEN (Wednesday, June 13, 2012) - The Ohio Department of Transportation (ODOT) announces that it is in the process of finalizing systematic upgrades of the Do Not Enter, Wrong Way and One Way signs to the 2012 OMUTCD (Ohio Manual on Uniform Traffic Control Devices) standards. 
Drivers along the Toledo Metro Interstate may have noticed the upgrades on existing signs along freeway and expressway interchanges  The work currently being performed is part of our ongoing systematic sign replacement program, which provides for traffic control signs to be replaced on a regularly scheduled basis to assure adequate levels of nighttime visibility.
By the end of 2012, ODOT intends to upgrade signage along freeway and expressway interchanges to enhance the visibility of signage for wrong way drivers.  These upgrades were determined after researching the best practices in Ohio and the United States and a review of the appropriate state and federal standards.         
On all interchange ramps in Lucas, Henry, Ottawa, Sandusky and Wood counties, ODOT will install supplemental wrong way signs on both of the existing wrong way installations on the non-cloverleaf exit ramps.  These supplemental wrong way signs will be installed at a three foot mounting height.
Research indicates that a lower mounting height makes the signs more visible at night because lower signs are in the path of a car's headlights and impaired and older drivers, who tend to drive with their eyes low, look for visual cues from the pavement area.
Additional countermeasures for interchanges where the entrance and exit ramps are side by side (partial cloverleaf interchange) include installing dual directional route marker assemblies at the ramp ends and the installation of pavement marking arrows for positive guidance on the entrance ramps.
Wrong way crashes are relatively infrequent but are more likely to produce serious injuries and fatalities compared to other types of crashes. Driving the wrong way on freeways has been a traffic safety concern since the interstate highway system was developed.
ODOT will remain committed to improving traffic safety and will continue to review items for future consideration.
