To identify examples of freight mode shift, the research team compiled a list of projects culled from a wide range of sources. This sub-section documents the approach, which included these activities:
- Interviews with subject-matter experts;
- Online research and literature review;
- Analysis of the TIGER grant application program evaluation database; and
- Analysis of over 30 American Association of State Highway and Transportation Officials (AASHTO) “The Case for Freight” reports.
Subject-matter expert interviews
To implement this method, the research team interviewed officials from government, associations, major carriers, and members of the panel and research team. The interviewers provided the experts with a brief introduction to the National Cooperative Freight Research Program (NCFRP) study effort, and asked them to identify successful mode shift projects. Interviewees were also asked to identify other experts who might be able to suggest additional potential case studies.
Table 44 and 45 summarize the interviews with experts. The tables provide the date of each interview, names of the organization and staff, and a summary of the results. In total, the research team interviewed nine individuals representing a cross-section of local, state, and federal agencies and private freight industry experts. The team also suggested other project examples based on its collective knowledge of major goods movement projects that might offer the data needed for this research effort.
In addition, several members of the NCFRP panel for this study provided additional feedback on an initial list of potential case studies, including suggestions for additional types, and individual case studies. Table 46 summarizes the written comments and interviews with panel members.
