The Project
• Arterials are the most challenged facilities in Atlanta
• Competing travel interests• Cohesive planning, operations, and
management
EFFICIENT PROJECT IMPLEMENTATION

Overall Project Goals
• Prioritized arterial roadway network• Develop guidelines on management and
design• Create a Geographic Database• Perform case studies to test concept
designs

Case Studies
• Transportation Assessment for MMCS• 5 Case Study Corridors• Case Studies selected based on differing
developments, area types, and roadway configurations

Conclusion
• Use regional travel demand model• Bridge the gap between different local
agencies for consensus in development strategies
• Using the appropriate tools to “funnel” travel demand down to peak hour microsimulation-level traffic
