Update to Procedure for Determining Work Zone Speed Limits

The objective of this research is to update the procedure for determining work zone speed limits by: (1) collecting and analyzing work zone speed and crash data to test the conclusions from National Cooperative Highway Research Program (NCHRP) Research Results Digest 192 to determine if present-day data verifies the conclusions or whether different conclusions are drawn from new data; and (2) developing an updated procedure for determining work zone speed limits to be used for construction and maintenance operations and accommodate, to the maximum extent possible, the interests of motorists, workers, pedestrians, bicyclists, and transit operators and users.
