Travel times are highly variable due to rapidly changing conditions along a segment or corridor. Conditions frequently change due to seasonal fluctuations in demand, road construction, incidents, special events, weather, and active speed enforcement activity. With the emerging probe data sources, it is now possible to develop multi-scale reports that characterize over mobility over varying highway segment lengths and time periods to characterize system mobility. The outcome of this project will be mobility reports that can be used for both internal assessments as well as communication system performance to the public.
