Quantification of urban-freeway congestion and analysis of remedial measures. Final report, September 1985-October 1986

Technical Report ·
OSTI ID:5332146

This report presents an estimate of existing (1984) and future (2005) levels of congestion on the Nation's urban freeways based on data contained in FHWA's Highway Performance Monitoring System (HPMS) database. Estimates of congested travel, delay due to recurring congestion, delay due to non-recurring (incident) congestion, and wasted fuel are made on a national basis. Estimates of the aggregate impacts of several techniques for reducing freeway congestion, such as widening, surveillance and control systems, low-cost geometric improvements, and demand-reduction strategies are also made.
