MODELING AND MAPPING TRAFFIC - CONGESTED CORRIDORS FOR STATEWIDE DECISION SUPPORT

摘要

In this research, we applied two different methods to analyze road traffic congestion corridors in Georgia. The 2008 GDOT datasets were analyzed and visualized. Two approaches showed significant differences; however, the most congested corridors on GA- 400 and I- 85 above the Hartsfield international airport appeared in similar patterns on both maps. I - 285 showed large differences. VCR revealed more congestion in arterial roads and in mid to large cities in Georgia. Decision makers will benefit from the results in planning short - term solutions and long - term strategies. We plan on validating the results with field checks in the very near future. We also plan on incorporating more variables such as exits, traffic signals and curvature in estimating choke points.
