LEVELS OF SERVICE--GETTING READY FOR THE 21ST CENTURY

Vehicle operating conditions are often quantified and described in terms of level of service (LOS) of the facility. LOS labels refer to the degree of service success, LOS "A" indicating the highest level of service and LOS "F" indicating failure. Urban expansion, though, has led to increased traffic volumes and widespread traffic congestion. Additional labels, beyond LOS F, are necessary to distinguish between varying degrees of facility failure (delay lengths and travel speeds). This article proposes three separate mechanisms to define facility failure, including creating levels of service beyond LOS F, reporting problems beyond traditional peak periods, and assigning a numerical grade to intersections based on the development of a Congestion Index.
