guidance as this document was developed. Thanks also go to Quentin Witkowski at Western Michigan University’s Evaluation Center for his efforts at reviewing literature and organizing material. Interviews with the Steering Committee of the C3RS program provided much needed information and wisdom about success factors in close call reporting system. They gave us the perspective we needed to interpret the literature in a fashion that served the purposes of this evaluation. Tom Raslear at the FRA’s Office of Research and Development provided the funding and the inspiration needed to implement and evaluate C3RS. We thank him for his vision and his persistence.
