Topic: New Bottleneck Tracking & Ranking Algorithm
Organization: Center for Advanced Transportation Technology Laboratory
Presenter: Drew Lund (Database Administrator)
VPP Suite Tool: Bottleneck Ranking
Description: The CATT Lab has developed a new algorithm for its Bottleneck Ranking app to more accurately identify bottlenecks, better account for the dynamics (grow, shrink, merge, etc.) and enhance the ranking calculations. There are also a number of improvements to displays, graphics, maps & tables, as well as much faster results, with no restrictions (e.g.; no longer limited to a 3-month maximum date range.)
Highlights: Drew Lund provided a brief recap of the need for change, what changed, some new terminology and some "storyboards" of different bottleneck conditions to illustrate how impacts change over space and time. Drew then conducted a live demo of the new Bottleneck Ranking app, from query page entries to a walk-though of the results and how to interpret them.
