As a single wheel turns, it is subject to centrifugal forces and gravity that keep it upright. This gyroscopic motion can be significantly affected by the road surface.

Work Zone Hazards
Work Zone Hazards The Obvious
Work zones tend to be more dangerous for motorists. Bikers are especially at risk for the following hazards: • Rocks and debris on the road • Road drop-offs and uneven pavement • Shifting lanes • Pooling water • Suddenly stopped traffic • Workers near the road • Areas with no shoulders

Safety Edge Shoulder Treatment
Safety Edge Shoulder Treatment The Safety Edge Shoe creates the Safety Edge. It is a special edging device that can be installed on new or existing resurfacing equipment.

Safety Edge Shoulder Treatment Sharp, steep pavement edge drop-offs can contribute to crashes.
Safety Edge Shoulder Treatment • Pavement edge drop-off on highways has been linked to many serious crashes, including fatal collisions. To mitigate vertical drop-offs, FHWA advocates installing the Safety Edge on pavements during paving or resurfacing projects. This technology allows drivers who drift off highways to return to the pavement safely. • Roadway departures account for over half of all fatal crashes. Not all of these crashes involve speeders and drunk drivers. Some could have been easily prevented if a vertical pavement edge drop-off had not been present.

Safety Edge Shoulder Treatment The FHWA has joined with state and local agencies in 20 states to sponsor or initiate project demonstrations installing this technology. Working together with State partners, contractors, equipment manufacturers, and the industry on this 21st century initiative, we can prevent the tragedy of pavement edge drop-offs.
• Fatalities and Work Zone Fatalities

• The number of fatal injuries involving motorcyclists has
increased nationally from 3,365 in 2002 to 5,409 in 2008. Fortunately in 2009 the total number of fatal injuries decreased to 4,595. • Additionally from 2006 to the end 2010 there were 336 work zone related crashes resulting in 82 incapacitating accidents and 10 fatalities. Source: NHTSA.

The objective is to raise awareness of the issues that motorcyclists deal with relative to the design, construction, and maintenance of roadways. We looked at different areas that present unique challenges to the motorcycling public. The job of the designers and construction and maintenance personnel is to provide a safe, durable pavement for all road users, whether they drive an 18-wheeler or riding a two-wheeled motorcycle. Remember to look at your project through the eyes of a motorcyclist.
And don’t forget our friends on bicycles!
