USE OF A MULTIPLE ROUTING TECHNIQUE FOR ONE PASS CAPACITY RESTRAINT ASSIGNMENTS

MULTIPLE ROUTING, AS PRESENTED HERE, ADDS THROUGH ITS STOCHASTIC PRINCIPLE A LONG-SOUGHT ELEMENT OF REALISM TO THE TRAFFIC ASSIGNMENT PROCESS. THIS PRINCIPLE ELIMINATES THE PROBLEM ASSOCIATED WITH THE MINIMUM PATH PROCEDURE, WHICH LEADS TO EXTREMELY UNBALANCED FLOWS WHERE MORE THAN ONE ACCEPTABLE ROUTE EXISTS BETWEEN PAIRS OF NODES. WITH THE MULTIPLE ROUTING PRINCIPLE AS ITS BASIC FRAMEWORK, A ONE-PASS INCREMENTAL CAPACITY RESTRAINT PROCEDURE IS PRESENTED, WHICH PROVIDES A FLEXIBLE AND ECONOMICAL TOOL FOR PRODUCING TRAFFIC ASSIGNMENTS WITH STABLE SPEED-FLOW RELATIONSHIPS. RESULTS OBTAINED WITH THIS PROCEDURE INDICATE A LEVEL OF ASSIGNMENT ACCURACY WHICH IS EQUIVALENT OR SUPERIOR TO THAT OBTAINED WITH FOUR ITERATIONS OF THE FREQUENTLY USED AVERAGING PROCEDURE. /AUTHOR/
