註釋The overall safety and traffic operations implications of larger trucks are not clear-cut. While several techniques permit the evaluation of the impact of larger trucks on transportation costs and highway costs: (1) accident frequency and severity as a function of vehicle size of weight, and (2) data relating truck size and weight, to highway geometry and traffic operations, at a national level are virtually nonexistent. Prior to the development of a work plan for the collection of empirical truck-related data at a series of sties across the United States, a review of existing literature was performed. The material has been organized into three major subcategories. 1: Truck exposure characteristics (registration and mileage), 2: Truck accident characteristics, 3: Truck traffic operations characteristics. Although accident data is available for interstate motor carriers, there is no national accident data, truck exposure data, or truck performance data (speed, delay, acceleration noise and other such traffic stream behavior measures) that have been collected utilizing both a common truck subpopulation classification scheme and roadway typology utilizing urban/rural, interstate/primary/secondary, descriptors.
