This video is the result of a research effort by faculty and students at the University of Tennessee to document and study the hazards associated with railway grade crossings on bicycle safety (published in the Journal of Transport & Health). Most video was captured in August and September, 2014 on Neyland Drive, in Knoxville TN. The City of Knoxville has since realigned both rail crossings largely solving the safety problem. The video is 2x actual speed.
