Tests of Dynamic Extensions to a Family of Trip Table Refinement Methods
This paper addresses the problem of using traffic counts to ascertain dynamic origin–destination (O-D) tables when dynamic traffic assignments are performed within a traffic window. A family of dynamic O-D trip table estimation methods containing two previously unexplored members (single factor and biproportional) is proposed to solve this problem. The family is tested on a traffic network for the US-45 corridor in Milwaukee, Wisconsin. The tests show that dynamic traffic assignments can be made to match ground counts by a dynamic extension to a technique conceptually similar to Fratar factoring of both origins and destinations from a static O-D table. The two methods that directly solve for origin or destination factors have computational and statistical advantages over whole-table dynamic O-D trip table estimation procedures. Both methods have results that can be readily interpreted.
