QUALITY-OF-SERVICE OF ROAD TRAFFIC AND ITS MEASUREMENT

A UTILITY BASED APPROACH

Abstract

Quality-of-service is of major interests to drivers, who are the consumers of road service. However, currently used measures of level-of-service to evaluate the traffic condition of road sections are not necessarily linked to the perceived level-of-service by the drivers. This paper proposes a framework to measure the driver's perception to the quality of service. The proposed framework has a two-layer structure consisting of microscopic and macroscopic levels with aggregation model. A series of analysis based on the proposed framework is conducted, and finding process of a rather good index of level-of-service is also demonstrated.
