Road Diet Guide
Overview
In the mid 20th century many urban streets were designed with excess automotive capacity in order to accommodate future peak hour traffic. Much of this traffic never materialized or dissipated due to suburbanization and other factors. Now, many cities are maintaining excessively wide streets which are under-used and which only offer a single transportation option for automobiles. These under-utilized traffic lanes are a valuable land bank and provide enormous opportunities to re-purpose public space for more sustainable transportation uses.
Research and numerous case studies have shown that road diets (removing one or more automobile traffic lanes) are one of the most effective traffic safety measures and provide opportunities to use under utilized right-of-way for pedestrian, cycling or transit facilities...
The importance of road diets cannot be overstated. They offer multiple benefits, including traffic calming, a reduction in crash rates across all modes, and opportunities to dedicate underutilized right of way to sustainable modes and human scaled public spaces.
