Roadway Reconfigurations

Roadway Reconfigurations, also known as Community Livability Projects or Road Diets, typically involve 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).

Benefits of Community Livability Project installations may include:

  • An overall crash reduction of 19 to 47 percent.
  • 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.
  • The multiple threat pedestrian crash type is essentially eliminated.
  • Opportunity to install pedestrian refuge islands, bicycle lanes, on-street parking, or transit stops.
  • Traffic calming and more consistent speeds since the most prudent driver now sets the speed for all drivers to the rear.
  • A more community-focused, “Complete Streets” environment that better accommodates the needs of all road users.

A Roadway Reconfiguration can be a low-cost safety solution when planned in conjunction with a simple pavement overlay, and the reconfiguration can be accomplished at no additional cost. Because of a proven track record for improving safety within communities, the Federal Highway Administration has included Roadway Reconfigurations on their top 20 list of Proven Safety Countermeasures.
