The impact of large trucks on urban freeways has been the subject of increasing concern among traffic engineers and transportation agencies. Fueled by the publicity given to major truck accidents, the perception has developed that trucks contribute disproportionately to accidents and to congestion caused by incidents on urban freeways. Major truck incidents, including vehicular collisions, overturned trucks, spilled loads, and fires, can block much or all of a freeway and result in congestion which lasts for several hours. On a heavily traveled urban freeway, thousands of hours of vehicle delay can result from a single major truck incident. Various proposals have been advanced for alleviating the problem of truck-related incidents on urban freeways, including such radical strategies as banning trucks from some or all freeways during peak periods. The study addresses one aspect of the impact of truck-related freeway incidents, namely the economic costs of such incidents. Such costs consist of accident-related costs (vehicle repairs, medical expenses, economic losses associated with fatalities), increased vehicle operating costs due to the additional congestion, clean-up costs for such events as spilled loads or fires, and the economic costs of delay to motorists.
