A METHOD FOR MEASURING THE EFFECTIVENESS OF A GIVEN ASSIGNMENT METHOD AND AN APPLICATION TO THREE DIFFERENT METHODS

A METHOD OF MEASURING THE EFFECTIVENESS OF A GIVEN ASSIGNMENT TECHNIQUE IN ACHIEVING A GIVEN ROUTE CHOICE CRITERION IS PRESENTED. THE ROUTE CHOICE CRITERION TAKEN IS WARDROP'S FIRST PRINCIPLE OF EQUAL TRAVEL TIMES ON ALTERNATE ROUTES. THE APPLICATION TO THE ALL-OR-NOTHING ASSIGNMENT, THE BUREAU OF PUBLIC ROADS ASSIGNMENT, AND THE WILBUR SMITH ASSIGNMENT INDICATES THAT FOR LOW DENSITY NETWORKS THE CRITERION IS SATISFIED OR NEARLY SATISFIED FOR EACH. FOR HIGH DENSITY NETWORKS, WHILE THE RELATIVE EFFECTIVENESS DEPENDS ON THE SPEED-VOLUME RELATIONSHIP ASSUMED, NONE OF THE ASSIGNMENTS SATISFIES THE CRITERION. THE METHOD SHOULD MAKE POSSIBLE A DETERMINATION OF THE BEST AVAILABLE ASSIGNMENT FOR A GIVEN SITUATION WHERE SOME IDEA OF THE NETWORK DENSITY IS KNOWN. /AUTHOR/
