The four E's of safety are: engineering, enforcement, education and emergency medical services. These are the foundation of all Roadway Safety Program activities.
Engineering: While human factors are the main contributing reason in traffic crashes, well-engineered roads can mitigate the severity of such crashes or prevent them altogether. Even low-cost improvements, such as striping, raised pavement markers, rumble strips, speed bumps and conspicuous signage have proven to be effective counter measures.
Enforcement: Roadway Safety Program funds increased police patrols, as consistent enforcement is the most effective short-term measure to reduce traffic crashes - particularly in safety corridors, where fines for traffic violations double.
Education: Roadway Safety Program helps coordinate ongoing education, training and research on how road engineering impacts traffic safety. In addition, the program raises awareness among key stakeholders and the general public about the role of safety corridors and their effect on crash reduction.
Emergency Medical Services: Timely delivery of emergency medical services is essential to reducing fatal outcomes. The Roadway Safety Program works to ensure that road engineering and driver behaviors do not impact the timely delivery of EMS through ongoing education and partnerships with a variety of state and local public works partners.
