Abstract:

As the new 2010 Highway Capacity Manual (HCM) approaches, an understanding of the history of speed-flow curves is useful in understanding the manual's new curves and their implications. This paper reviews that history, from the 1950 HCM through the current 2000 edition. The paper reviews both the data sources and judgments that were involved in their development.

Supplemental Notes:

The DVD lists the title of this paper as: Speed-Flow Curves for Freeways in the Highway Capacity Manual: Historical Perspective.
