- (a) Once the purpose and need has been identified, the next step is to define the scope of the operational analysis, both geographic and temporal.
- (b) This should be accomplished during early coordination before the IJR is developed.
(c) When developing the scope of the operational analysis, several questions should be considered, including:
- (1) What are the limits of the proposed project?;
- (2) What is the proximity to adjacent interchanges and intersections?;
- (3) How does the study area influence operations at adjacent locations within the transportation network?;
- (4) What alternatives are likely to be considered?;
- (5) What physical elements within the network can be analyzed to support the purpose and need?;
- (6) How many hours of congestion are present today, and how will this likely change in the future?;
- (7) Will the operational characteristics of the surrounding area change in the future and, if so, will an understanding of how this relates to the study area warrant analysis?;
- (8) What degree of precision is required to make an informed decision?;
- (9) Will varying travel demand patterns and land use scenarios be considered to assess how robust and flexible the alternatives are?; and
- (10) In corridors where the potential exists for future multiple interchange additions, has a corridor study been completed?
