OFFICE OF SAFETY Proven Safety Countermeasures Road Diets (Roadway Reconfiguration) A Road Diet, or roadway reconfiguration, can improve safety, calm traffic, provide better mobility and access for all road users, and enhance overall quality of life. A Road Diet typically involves converting an existing four-lane undivided roadway to a three-lane roadway consisting of two through lanes and a center two-way left-turn lane (TWLTL). Safety Benefits: 4-Lane to 3-Lane Road Diet Conversions 19-47% reduction in total crashes.1 BEFORE AFTER Before and after example of a Road Diet. Source: FHWA Benefits of Road Diet installations may include: • Reduction of rear-end and left-turn crashes due to the dedicated left-turn lane. • Reduced right-angle crashes as side street motorists cross three versus four travel lanes. • Fewer lanes for pedestrians to cross. • Opportunity to install pedestrian refuge islands, bicycle lanes, on-street parking, or transit stops. • Traffic calming and more consistent speeds. • A more community-focused, Complete Streets environment that better accommodates the needs

OFFICE OF SAFETY Proven Safety Countermeasures Appropriate Speed Limits for All Road Users There is broad consensus among global roadway safety experts that speed control is one of the most important methods for reducing fatalities and serious injuries. Speed is an especially important factor on non-limited access roadways where vehicles and vulnerable road users mix. A driver may not see or be aware of the conditions within a corridor, and may drive at a speed that feels reasonable for themselves but may not be for all users of the system, especially vulnerable road users, including children and seniors. A driver traveling at 30 miles per hour who hits a pedestrian has a 45 percent chance of killing or seriously injuring them.1 At 20 miles per hour, that percentage drops to 5 percent.1 A number of cities across the United States, including New York, Safety Benefits: Washington, Seattle and Minneapolis, have reduced their local speed limits in recent years in an effort to reduce fatalities and serious injuries, with most having to Traffic fatalities in the City secure State legislative authorization to do so. of Seattle decreased 26 percent after the States and local jurisdictions should set appropriate speed limits to reduce the significant risks drivers impose on others—especially vulnerable road users—and city implemented on themselves.

OFFICE OF SAFETY Proven Safety Countermeasures Backplates with Retroreflective Borders Backplates added to a traffic signal head improve the visibility of the illuminated face of the signal by introducing a controlled-contrast background. The improved visibility of a signal head with a backplate is made even more conspicuous by framing it with a 1- to 3-inch yellow retroreflective border. Signal heads that have backplates equipped with retroreflective borders are more visible and conspicuous in both daytime and nighttime conditions. This treatment is recognized as a safety countermeasure is to adopt human factors enhancement of it as a standard treatment for Safety Benefits: traffic signal visibility, conspicuity, signalized intersections across a 15% and orientation for both older jurisdiction or State. and color vision deficient drivers.
