1/ In 1999, updated capacity (service flow) calculation procedures were instituted in the HPMS data reporting process. The procedures are based on the Highway Capacity Manual, Third Edition, 1998, published by the Transportation Research Board. Some differences from other tables may be noted because these values are estimated from sample data and do not include samples entirely on structures.
