Recursive Estimation of Traffic Variables: Section Density and Average Speed

Simultaneous recursive estimators for aggregate variables, section density, and mean speed, are derived. The estimators are simple and easily suitable for digital implementation. Performances of the estimators are evaluated utilizing the real traffic data obtained over a three-quarter mile section of the Long Island Expressway, New York, and data obtained from digital simulation of freeway traffic.
