4.2.3 Final/Approved Schematics and Design Stage
Final/Approved Schematics and Design-stage analysis is a high-detail analysis that is often performed with more data than projects in other stages of development. While study limits for projects in this stage could be broad or narrow, they are well defined.
Final/Approved Schematics and Design-stage analyses:
- Are conducted for projects beyond the preliminary design stage;
- Answer questions generated by previous stages of analysis;
- Often necessitate substantial amounts of data to be collected; and
- May use tools that are stochastic (account for randomness) and microscopic (evaluate individual vehicles). The use of microsimulation (microscopic) tools depends on the scope, complexity, traffic operational conditions, and MOEs of the project
