TOWARDS AN AREAWIDE SERVICE MEASURE

With the introduction of the year 2000 edition, the "Highway Capacity Manual" (HCM2000) has taken its first steps towards computing and predicting performance measures for areawide analysis. Chapter 30 of the HCM2000 presents an overview of the general methodology and demonstrates the application of this methodology through several case studies. While Chapter 30 presents several regional measures of performance, it does not suggest nor advocate selection of one of these measures as "the" service measure. This paper describes important characteristics of an areawide service measure, formulates a performance measure that satisfies these characteristics, and presents computational results of this service measure for the Atlanta, Georgia, metropolitan area.
