WHAT THIS IS ABOUT
When a vehicle leaves the travel lane or the roadway, the results can be deadly. More than half of the annual fatal crashes in the U.S. relate to roadway departures. Roadway departure crashes are the leading cause of traffic deaths in many states. This workshop provides participants with some tools for addressing roadway departure crashes. Topics covered include a discussion of engineering countermeasures as well as implementation strategies.
One, often low-cost, strategy to address this issue is to reduce the potential for leaving the roadway, i.e., techniques to help keep vehicles on the roadway. Use of signing, delineation and rumble strips/stripes to reduce roadway departures is described with specific reference to relevant sections of the Manual on Uniform Traffic Control Devices. The significance of roadway geometry and pavement friction in helping to keep vehicles on the roadway is also discussed. For those vehicles leaving the traveled way, it is important to try to improve the chances for a safe recovery. Techniques for improving shoulders and slopes and ditches are reviewed. Removing or relocating objects such as trees and utility poles in the clear zone are also addressed. The workshop concludes with discussion of how to minimize the severity of roadway departure crashes that do occur. Relevant techniques include breakaway supports, making roadside features traversable and shielding obstacles. Enhancing mailbox safety is also discussed.
WHO SHOULD ATTEND?
This workshop should be of interest to state, county and municipal transportation, traffic and safety engineers, technicians, street supervisors, maintenance personnel and planners involved in roadway safety. Designers (engineers and landscape architects) should also find the workshop of interest.INSTRUCTOR
