The report is concerned with the characteristics and consequences of over 9,000 truck-involved freeway accidents and non-accident incidents in a three-county case study region in Southern California. The research was conducted in two major phases: (1) identification of the number and type of truck-involved accidents occurring on freeways in the region, together with statistical analyses of the influence of a wide range of conditions on the frequency and severity of these accidents; and (2) estimation of the impact of these accidents on the freeway system in terms of congestion and delay, and estimation of the total annual economic costs of these accidents. Chapter Two reports the results of statistical analyses of the salient characteristics of over 9,000 truck-involved freeway accidents that occurred in the region during 1983-84. Chapter Three focuses on the immediate consequences of these accidents: accident severity (i.e. injuries and fatalities), incident duration, and lane closure. Chapter Four is an analysis of 424 major incidents involving large trucks on freeways in the region during 1983-85. Chapter Five focuses on the impacts of truck-involved mainline collisions on freeway congestion and delay; simulation models are used to estimate total delay attributable to such collisions for the 1987-88 period. Chapter Six focuses on the total economic costs of these accidents.
