Authority for the study is vested in Section 307 of Title 23,United States Code.The Department of Transportation’s, Division of Transportation System Information collects the HPMS data from the cities, counties, Metropolitan Planning Organizations (MPOs) and other partners and stakeholders. The HPMS database maintains federally classified physical condition and performance characteristics on all public road mileage for rural and urban areas. The arterial and collector road systems (the prominent streets and roads) are then statistically sampled to estimate the current needs and future performance of the system. The type of information sampled includes: traffic operations, structural section, pavement condition, geometrics, environmental, future Annual Average Daily Traffic (AADT) estimate,and other technical information
