FREEWAY LEVEL OF SERVICE: A REVISED APPROACH

Concepts, philosophies, and standards for freeway level of service presented in the 1965 Highway Capacity Manual are reviewed. A revised approach is developed that incorporates density in the definition of standards. Speed-flow relations under ideal conditions are approximated based on secondary source data and a limited number of pilot field surveys associated with current work. The recommendations made for new level-of-service standards for freeways are based on recalibrated speed-flow relations and incorporate density as a parameter. /Author/
