Effective Countermeasure Selection for Diverse Populations

This guide covers methods for selecting targeted countermeasures to improve road safety, focusing on diverse cultural and geographic groups. Major topics include site review methods, resources for countermeasure selection, tools for comparisons, and market research techniques. It also addresses low-cost safety improvements and an integrated management process to reduce highway injuries and fatalities statewide. Learn how to plan and implement action plans, evaluate performance, and apply suggested countermeasures such as adding illumination, improving drainage, and managing driveway access points.

  6. Countermeasures That Work

  7. Remove sight distance obstructions Add or change turn lanes Improve design of acceleration/deceleration lanes Add illumination Use median barriers Recognize ability of pedestrians to cross street Improve superelevation Improve drainage Modify road shoulder and lane widths Manage/consolidate number of driveway access points Realign approaches Suggested Countermeasures (2006)

  8. Road safety audits Rumble strips and rumble stripes Median barriers Safety edge Roundabouts Left and right turn lanes at stop-controlled intersections Yellow and all red change intervals at traffic signals Median and pedestrian refuge areas in urban and suburban areas Walkways Suggested Countermeasures (2008)
