USLIMITS2 is a web-based tool designed to help practitioners set reasonable, safe, and consistent speed limits for specific segments of roads. It is applicable to all types of facilities, from rural local roads and residential streets to urban freeways. The tool provides a suggested speed limit value based on 50th and 85th percentile speeds, roadway characteristics, and (optional) crash data.
