(1) Please note that due to data review and production issues with the 2021 HPMS data, some anomalous and/or missing data may exist. Due to conversion from English to metric units and to rounding, individual cell values may not agree with corresponding vehicle-miles table cell values. Travel for the rural minor collector and rural/urban local functional systems are estimated by States based on models or other means and provided to the FHWA on a summary basis. Travel for all other systems are estimated from State-provided roadway segment level data in the Highway Performance Monitoring System.
