Format of Each Case Study

Printable Version Printable Version

Each case study is organized similarly:


Introductory materials;


Problems (and subproblems); and

bullet Analysis and discussion.

The introductory sections are designed to acquaint the reader with the important characteristics of the case study, including the transportation facilities of interest, the relevant traffic characteristics, the surrounding land uses, the key stakeholders and their issues of concern, and the general scope of the investigation that is about to be undertaken. These sections also provide an overview of the analyses that will be undertaken later in the chapter. Based on this, they also discuss the range of possible analysis tools and their associated data requirements. This discussion leads to the identification of the particular analysis tools that will be applied to the subsequent problems in the chapter.

Each problem is separately discussed, and in many cases more than one analysis must be conducted to address all the issues the problem raises. Thus, each problem is typically associated with several sub-problems, each of which constitutes the application of a single analysis procedure. Within each sub-problem, the information necessary to conduct the analysis is presented, along with the analysis results. The step-wise application of the analysis procedure is conducted through use of appropriate software and is not explicitly discussed in the HCMAG. This avoids repetition of information already available and published in the HCM and/or software reference manuals.

The analysis and discussion sections of each case study expand upon the findings of each analysis and problem to identify the key insights that have emerged and the important conclusions that can be reached. Within this section, the HCMAG critically reviews the results to ensure that they are reasonable, meaningful, and consistent. It may also deal with issues of sensitivity analysis, the feasibility of the recommended solutions, methods for presenting results to decision makers, and possible next steps.
