... NCHRP 20-78: Final Report Page 29 CHAPTER 3: CASE STUDY SELECTION CRITERIA AND RECOMMENDED TRANSPORTATION RESEARCH PROJECTS Introduction Task 3 in the study work plan required the study team to describe the characteristics of transportation research projects that would be useful for in-depth evaluation and to identify a suitable number of projects for Task 4 case study evaluation. We conducted seven in-depth case studies, and each individual case study consisted of a "whole" study, in which facts were gathered from various sources about the entire lifecycle of the transportation research project -- from research proposal to funding (where possible)
