This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, examines the procedures that highway agencies and railroads follow to develop agreements for highway projects that cross or lie alongside railways. It provides a comprehensive collection of successful practices and standard processes that promote cooperation between railroads and public agencies and that can help them reduce the time and cost of project reviews. The report also includes a series of model legal agreements.
