About this file
This document is a traffic signal installation design plan prepared by Lowe Engineers for the Georgia Department of Transportation (Georgia DOT), specifically for a signal installation project at the intersection of SR9/Roswell Road and Northridge Road. The project involves replacing and upgrading traffic signal infrastructure, including installing new LED signal heads with backplates, APS (Accessible Pedestrian Signal) pushbutton stations, pedestrian countdown signals, and associated roadway markings. The design includes detailed phasing diagrams, signal legends, detection methods (including magnetometers, radar, and inductive loops), and regulatory signage for the intersection.
The project scope includes retaining existing signal equipment and strain poles while replacing signal heads and pedestrian signals, installing new 10' pedestal poles, updating traffic striping with thermoplastic markings, and implementing pavement marking arrows. The materials list indicates quantities for various signal cables, signal face LED units, pedestrian signal equipment, and mounting hardware. Specific quantities include 8 pedestrian signal face housings, 2 pedestrian detection systems, and various traffic striping and marking elements. The design is dated February 14, 2025, and bears the Georgia DOT approval, with drawing number 27-0003 for signal plans and 27-0004 for signal details and quantities.
