Traffic Signals on Peachtree Street Corridor Adjusted to Improve Ped Safety
Peachtree Street in Midtown Atlanta is heavily used by pedestrians, and many of the intersections off Peachtree have high percentages of turning traffic, where cars can conflict with pedestrians. Working with the City of Atlanta and the Georgia Department of Transportation, Midtown Alliance recently installed new traffic signal sequencing to enhance safety for pedestrians at eleven intersections along Peachtree Street between 3rd Street and 17th Street. This project is part of the Midtown Traffic Operations Program (MTOP), a multi-faceted effort to create efficiencies that have reduced peak travel times in major Midtown corridors over the past two years.
New Sequence: Pedestrians get a head start in crosswalk
With the new signal timing, Leading Pedestrian Intervals (LPIs) give pedestrians a head start when entering an intersection by allowing pedestrians to begin crossing the street prior to turning vehicles. This extra window of time allows pedestrians to walk the distance of one travel lane before vehicles receive their green indication. This change increases pedestrian visibility in the crosswalk to turning vehicles, and should eliminate conflicts. Click here for a diagram explaining how it works.
We are studying additional intersections through this project to potentially expand this concept to other appropriate locations in Midtown.
