Comprehensive Regional Congestion Analysis
Based on its internal needs, VDOT will recommend an operational region, district, or metro region to act as first test case for developing a methodology for comprehensive data analysis for a larger geographical area. The traffic engineering analyses and performance measures planned are:
- List of bottlenecks
- Heat map of the peak period (or peak hour) of congestion
- List of travel time indices for key commuter routes
- List of buffer indices for key commuter routes
For the list of bottlenecks, STL will investigate the best bottleneck identification methodology to use among Chen et at. 2004, VTTI ABSIA, INRIX).
The work on this task will help VDOT get a comprehensive picture of traffic and congestion trends and will establish a methodology for calculating performance measures over a large geographical area.
