The Systems Planning Office of the Florida Department of Transportation has been one of the national leaders in funding research to develop level of service (LOS) planning analysis methodologies for alternative modes to the automobile. Past research funding by the Department has led to the development of LOS planning analysis methodologies for the modes of bicycles, pedestrians, and transit (bus). The mode of heavy trucks has traditionally not received specific attention as far as level of service is considered. Trucks are typically converted to an equivalent number of passenger cars and the Highway Capacity Manual (HCM) LOS analysis procedures determine a single LOS measure for the traffic stream as a whole, without distinction of possible LOS differences between the different modes operating in that stream. This report documents an exploratory investigation, and development, of a methodology for assessing the level of service of heavy trucks in the traffic stream separately from that of passenger vehicles, for basic freeway segments. This methodology is based on a relative maneuverability concept, which is a function of the ratio of percentage of free-flow speed of trucks to percentage of free-flow speed of passenger cars.
