40 The case study provides validation for the "Evaluating Reliability Needs and Deficiencies" and "Incorporating Reliability Measures into Program and Project Investment Decisions" steps in the guide. The case study was successful in demonstrating how agencies can use sketch-planning methods to assess the reliability impacts for a package of operations strategies within a corridor and then advance these projects into the region's longrange transportation plan.
