Book excerpt: ABSTRACT: The concept of level of service (LOS) is central to the Highway Capacity Manual (HCM) and is used to assess the performance of all types of roadway facilities. Many transportation infrastructure funding decisions are based on LOS analyses and the resulting LOS designations are intended to represent user perceived quality of service. This paper provides an overview of the evolution of the two-lane highway LOS analysis methodology and identifies weaknesses in the methodology as perceived by the Florida Department of Transportation (FDOT), as well as other HCM users. In particular, this study focuses on deficiencies in the methodology (in terms of performance measures, LOS thresholds and service volumes) with respect to rural developed two-lane highways, such as those facilities through small towns or developed coastal areas.
