Miscellaneous Topics of Interest CHSP-Local Roads focus group Rumble Stripes initiative Road safety audits or assessments Sign inventory potential County driveway slope flattening program
CHSP-Local Roads Group Proposed Strategies, listed in order of team preference 1. Undertake an in-depth study of fatal and serious injury crashes on very low volume rural roads, examining where and when these incidents occur and who is involved. 2. Study and promote the use of paved shoulders and rumble stripes on paved local rural roads to reduce run-off off-road crashes and promote more visible, longer lived edge line markings, particularly at potentially higher risk k locations such as curves. 3. Provide GIS based crash data to local agencies and planning organizations o on cyclical basis to identify locations of potential concern. 4. Support programs of concentrated enforcement on low volume rural ral roads and high crash intersections with initiatives such as Safety Zones. 5. Provide support and analysis information for enhanced enforcement efforts at urban intersections, such as automated enforcement 6. Support and provide instructional materials for driver educators through class materials, teaching aids, and pertinent crash information, with particular emphasis for driving on unpaved rural roads, seat belt use, speed, and alcohol consumption 7. Urge local rural agencies to examine very low volume roads for r possible needed safety improvements that can be accomplished at low cost such as signing g upgrades. 8. Promote a reduction in the statutory speed limit on unpaved rural r roads from 55 mph to 50 mph, day and night 9. Encourage local agencies to employ public information efforts to advise of safety initiatives and to acquaint drivers with potential safety concerns such as red r light running and high speed travel on unpaved surfaces. 10. Work with local agencies to establish and support multi-disciplinary traffic safety teams similar to the successful CARS group in the Quad Cities 11. Establish communication network with emergency responders in local areas to determine feasible methods of improving response times to serious crash sites
Rumble Stripes Study
Slope Flattening Program ~25,000 entrances treated so far Mostly higher volume paved roads All counties have participated
