Congestion Analysis 2023

The 2023 Congestion analysis page is a living page, as additional analysis is completed additional information will be added to this page. The information to be included on this page is a combination of default RITIS reports as well as analysis completed using PowerBI and Conveyal. Congestion activities are used to support ongoing planning activities as well as tracking and updating the Congestion Managment Process tied to the Regional Transportation Plan.

Data generated using RITIS Bottleneck Rankings tool. Total Delay — Base impact weighted by the difference between free-flow travel time and observed travel time multiplied by the average daily volume (AADT), adjusted by a day-of-the-week factor. This metric should be used to rank and compare the estimated total delay from all vehicles within the bottleneck.
