MULTIPATH SYSTEM TRAFFIC ASSIGNMENT ALGORITHM

This report is concerned with the assignment of traffic to a network of streets by systems techniques. A literature review of value theories and field studies governing route choice was undertaken. It was concluded from this review that various physical and psychological factors do govern the route choice by individuals. However, a value function which would deterministically reflect the psychological factors subjectively used by the aggregate of travellers could not be determined. It was therefore postulated that cost and time of travel would satisfactorily reflect the indeterminate value parameters used by an aggregate of travellers. Two types of value functions were used. One involved a straight cost variable where cost included operating, accident, quality of flow and time cost. The other involved a variable that was a product of time and cost where the cost included all of the prior items except time. A relationship between speed and cost was developed such that a continuous value function in relation to flow could be employed.
