1/ In 2001, updated capacity (service flow) calculation procedures were instituted in the HPMS data reporting process.The procedures are based on the Highway Capacity Manual 2000, published by the Transportation Research Board. For multilane facilities volume-service flow ratio is determined by dividing the peak traffic in the peak direction by the capacity.For all other facilities the ratio is determined by dividing the peak traffic by the capacity. Peak traffic is estimated as AADT *K, where K is the design hour volume (30th highest hour) as a percent of AADT. Some differences from other tables may be noted because these are estimated from sample data and do not include samples entirely on structures.
2/ Excludes 770 miles of Federal agency owned roads.
3/ 2004 data used.
