Prescott City Council Regular Voting Meeting —August 8, 2006 Page 3 4. Collisions Involving Deer: 22 collisions (17%) 5. Run Off Roadway Collisions: 5 collisions (4%) 6. Other Collisions: 17 collisions (13%) The following table lists the potential mitigation measures for the type of collision with pros and cons for each. Collision Potential Pros Cons/Inapplicability to Study Type Measure Area • Warns motorists of • No discernible darkness pattern in Rear End Reflective roadway conditions collisions Signing • May increase fixed object collision • Alerts inattentive • Noise Run Off Longitudinal drivers. Roadway Rumble Strips • Mitigates some run- off-road collisions • Alerts inattentive • Mitigates some collisions involving drivers inattentive driver Centerline • Mitigates some Rumble Strips crossing over center line type collisions Recessed • Illuminates travel lanes • No discernible darkness pattern in Pavement collisions Markings • Eliminates conflicting • High maintenance cost movements at minor • Intersection widening needed roads • Fixed object collision frequency may Median High Tension • Mitigates crossover increase Cross Over Cable Median collisions • Emergency vehicle response time Barrier • Reduces severity of increases collisions • Impacts operation of existing • Easy to install and signalized intersections uninstall • Maintenance of end treatments' • Restricts access • Restricts access • May impede snow removal • Eliminates conflicting • High implementation cost movements at minor • Drainage improvements necessary roads • Fixed object collision frequency • Mitigates crossover may increase F-Shaped collisions • Emergency vehicle response time Concrete • Reduces severity of increases collisions • Impacts operation of existing • Restricts access signalized intersections • Maintenance of end treatments' • Restricts access
