Better Travel Time Reliability, Improved Capacity Analysis

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores TRB's Highway Capacity Manual and NCHRP Report 825: Planning and Preliminary Engineering Applications Guide to the Highway Capacity Manual. The sixth edition of the HCM incorporates the latest research on analyzing the capacity of highways and streets, ensuring that the manual will continue to be a go-to resource for transportation agencies nationwide. Its companion, NCHRP Report 825, addresses applications that require less detailed and complex analyses, providing easy-to-use tools for planning and preliminary engineering. The report includes three case studies illustrating the use of these techniques.
