Not all crashes are created equal. Drivers, pedestrians and even roadways are all responsible for creating dangerous situations for other road users.
One of the most notorious high crash-rate roadways is the four-lane undivided highway that forces left-turning vehicles to slow down while actively in a through lane and cross dual lanes of oncoming traffic.
The Federal Highway Administration (FHWA) has analyzed a roadway reconfiguration known as the Road Diet to increase safety at these traditional four-lane undivided highways.
What is a Road Diet?
A Road Diet is a reconfiguration of a traditional four-lane undivided highway that converts into three lanes – two through lanes and a center, two-way left turn lane.
According to the FWHA, implementing a Road Diet will reduced crash rates 19 to 47 percent , improve mobility and better integrate the roadway into the surround area to enhance quality of life.
Why have a Road Diet?
As urban areas continue to promote programs for increased pedestrian and bicycle traffic, enhanced complete streets and livable spaces, Road Diets provide a low-cost solution to increase safety and better accommodate today’s vexing traffic problems.
Along with crash reduction, additional benefits of Road Diets include:
- Reduced roadway speeding
- Reduced aggressive driving behaviors
- Improved safety at pedestrian crossings
- Improved safety for bicyclists on roadways
- Increase bicycle usage
