intersections are marked with a cross-road sign. Signage on the roadway should be assessed periodically to "confirm compliance with the MUTCD." Turn Flares: Many intersections have sufficient pavement to improve the turning radius onto side roads but "are not striped accordingly." These intersections should be restriped. T-Intersection Signage: Black-on-yellow double arrow warning signs at key intersections may be added to alert motorists of the side route's junction with KY 9. Fog: The entire KY 9 corridor is plagued by fog, usually more than 60 days a year. A public education campaign may help. Visibility sensors and weather stations along the highway may help increase notification in these fog events. Highway Advisory Radio messages may also prove to be a benefit. Another major alternative would be the "automated lane indication system," which is similar to airport technology. Lighting installed in the pavement outlining the lane edges is "activated automatically when heavy fog conditions are sensed. By having the lanes outlined, the lights greatly increase visibility conditions in times of heavy fog, thus creating safer operating conditions. Additionally, these lights are recessed into the pavement so as not to hinder snow removal operations. Since they are used at virtually every commercial airport in the United States, the lights are readily available and qualified installation services are easily attainable. This type of system has been used successfully in many locations, including Interstate 64 near Charlottesville, Virginia." Rest areas, to keep vehicles and trucks off the road during fog times, may provide a "safe haven". Lighting: A few intersections along the route are currently lacking overhead lighting. Many complaints, however, is the lack lighting overall on the corridor. Roadway lighting can reduce the ratio of night to day crashes. Intersections without lighting should be reconsidered for lighting, as they can reduce nighttime crashes by 45%. Driver Fatigue: Numerous crashes are attributed to driver fatigue. Many fatal crossover crashes can be attributed to the drivers falling asleep at the wheel. Public awareness, rumble strips, and rest areas are all solutions to this problem. Landscaping, improved lighting, roadside and pavement reflective markings, and billboards which could be targeted toward drowsy drivers have been discussed as well. Median barriers may also be installed, but they cost around $80,000 to $1,000,000 per mile depending on the need to widen the road to accommodate the barrier. Truck Traffic: A large volume of trucks utilize the AA Highway, some to
