Analysis and Evaluation of Truck Traffic Restrictions and Separation Methods onInterstate Highways

摘要

The interaction of heavy and light vehicles is a widespread problem on USfreeways. Increases in truck and car volumes have added to existing problems related to pavement deterioration rate, safety, and traffic operations, and there is much concern over the severity of car-truck accidents and their corresponding traffic delays. This report examines various truck traffic separation schemes that have been proposed to solve the problems associated with mixed vehicle travel. Safety, highway operations, and pavement deterioration are the main considerations in this report; cost, feasibility, enforcement, environmental impact, and perception by the public were analyzed as well. This report also includes a summary of current truck traffic restriction policies within the US, obtained through a survey of transportation agencies in each of the fifty states.
