  1. ATLANTA REGIONAL COMMISSIONCONGESTION MANAGEMENT PROCESS UPDATE March 30, 2006

  2. ARC’s Congestion Management Process (CMP) is a SAFETEA-LU management system designed to manage congestion throughout the region and maximize the safety and mobility of people and goods. • The Program includes four steps • Identification • Understanding and Priority • Implementation • Data and Monitoring Introduction

  3. What is our analysis framework? • Congestion Management System Network • How do we identify congestion in the Atlanta region? • Model Data • Travel Time Index • Field Data • Travel Time Studies IDENTIFICATION

  4. CMSN

  5. Travel Time Index TTI A 30 minute free flow travel time that take 45 minutes in the peak would result in a 45/30 = 1.5 travel time index.

  6. Intensity Extent Duration Three Dimensions of Congestion

  7. Intensity of Congestion

  8. Duration of Congestion

  9. Extent of Congestion

  10. High Priority Facilities

  11. Draft Worst Arterials from Model

  12. Arterial Field Data Collection

  13. Activity Center TTI

  14. Transit TTI

  15. Activity Center Congestion • Total Delay • Average Travel Rate Activity Center Congestion

  16. Existing and Planned TTData

  17. The CMP program is diversifying the tool box • Planning models are coarse • The 4th dimension = crashes, weather • CMP mitigation strategies are operational • Are we making a difference? (before and after) • Can we capitalize on other studies? Data Collection and Monitoring

  18. Questions HNTB Project Manager Andrew Smith, AICP asmith@hntb.com ARC Project Manager Kofi Wakhisi, AICP KWakhisi@atlantaregional.com
