Abstract

Speed-flow-density relationships are commonly calibrated to what are referred to as “ideal” or “base” conditions. The latter term is most commonly used in recent years, as the word “ideal” carries a quality connotation that is not necessarily accurate. It is, however, important to know what the base conditions are, as highway capacity analysis methodologies most often apply various adjustment factors (Chapter 4) to the characteristics depicted for the defined base conditions.
