Case Study Technical Memorandum


The primary objective of the case study is to develop a process for estimating reliability performance measures and identifying reliability deficiencies based on traffic flow and incident duration data, and estimating the impacts of operations projects for the Knoxville Regional Transportation Planning Organization (TPO). The TPO has begun to carry out the update of the Long-Range Transportation Plan (LRTP) for the region and is undertaking Planning for Operations. This case study documents the incorporation of reliability into the agency’s transportation planning process. The case study also provides validation for the following steps in the Reference Guide:

  •  Measuring and Tracking Reliability;
  •  Incorporating Reliability in Policy Statements; and
  •  Incorporating Reliability Measures into Program and Project Investment Decisions.
