Roadway departure (RwD) is one of three safety focus areas (along with intersection and pedestrian/bicyclist crashes) with the greatest potential to reduce highway fatalities when using infrastructure-oriented improvements. FHWA’s Focused Approach to Safety provides resources to eligible high priority States to address RwD safety through technical assistance such as data analysis, training, and action plan development.
FHWA compares expected versus actual exposure criteria (RwD crashes by VMT, population, and center line miles) for each State. States are designated Roadway Departure Focus States if they have a ratio higher than 1.0 for all three measures.
Since 2009 FHWA has developed RwD Safety Implementation Plans in conjunction with RwD Focus States. The State-tailored plans include systemic implementation of low-cost treatments aimed at specific crash sub-types. The plan includes recommended RwD countermeasures and a set of strategies with deployment levels, and funds needed to achieve a substantial and cost-effective annual reduction in RwD fatalities. A technical workshop for State and local agency stakeholders is followed by delivery of the plan along with a presentation of the Implementation Plan that includes quantified costs and benefits, action steps for implementation, and templates for evaluation.
