Road Safety Enhancements
Road Sign Font
Research shows that Clearview font reduces fatal and injury crashes by 5 percent on rural roads, 23 percent on urban non-freeways, and 3 percent on freeways. The greatest reductions were realized at night for all crash types. These reductions were 26 percent for urban non-freeways, 34 percent for rural non-freeways, and 31 percent for freeways. In addition, a research survey found that drivers have a strong preference for Clearview font especially during inclement weather, at night and from a distance. Drivers 85 years and older had a strong preference for this font. MDOT has adopted Clearview font as the standard for all newly upgraded guide signs.
Brighter, More Visible Signs
MDOT has adopted this sheeting as the standard for warning signs. As warning signs are replaced, they will be done with the fluorescent yellow sheeting.
Traditional traffic signals can get visually "lost" against the sky. Adding a black backplate and face increases daytime signal visibility by 33 percent. In addition, adding a reflectorized border to the backplate enhances signal visibility even more - especially at night.
Countdown Pedestrian Signals
Countdown pedestrian signals display the number of seconds before the walk signal changes. This allows pedestrians to judge whether they have time to cross the street before the signal changes, as well as adjust their speed when crossing.
Wrong Way Warning System
Wrong Way Warning System is designed to help prevent motorists from driving the wrong way on freeways. Cameras in the system detect when a car is driving toward it; when that happens, high-intensity red LED flasher lights mounted on each of the wrong way signs are activated, warning drivers that they are going the wrong way.
