1 - Introduction

The purpose of this transportation improvement study is to investigate improvement options at the existing
intersections along Talley Street and Sams Street, including nearby intersections along SR 10/East College
Avenue Corridor and S. Columbia Drive. With new developments and the potential for future redevelopment in
the East Decatur Station area, the City desired to study the streets and identify opportunities to improve
multimodal safety and address congestion concerns at five intersections. Two known developments are the
Avondale TOD development, which is under construction at the corner of SR 10/E. College Ave and Sams Street,
and the new City Schools of Decatur Elementary School, opening in August 2019.

This report summarizes the traffic analysis effort, which includes recommendations for operational and
geometric improvements within the study area.

As part of the traffic analysis the following tasks were performed:

• Traffic volume projections
• Intersection capacity analysis at five locations for existing conditions, 2019 open year conditions, and
ten-year design year conditions
• Develop recommendation options at the study intersections
• Develop recommendation options along Talley Street/Sams Street
• Develop draft SRTS routes in study area
• Additional considerations
In a separate document, the existing conditions within the study area are summarized. This effort includes:
• Review of existing conditions from field observations and traffic data supplied by the City of Decatur
• Analysis of crash data obtained from GDOT Safety Office
