摘要：	Effective truck weight enforcement has become a critical issue as a result of the continual increase in the number of trucks on U.S. and Texas roads, as well as the impending truck-traffic-related provisions of the North American Free Trade Agreement (NAFTA). Feasible alternative technologies that should be considered by policymakers, engineers, and enforcement officers as they attempt to choose optimal truck weight enforcement methods for protecting the existing and future infrastructure are presented in this report. A review of the current conditions along the Texas/Mexico border, with respect to trade, infrastructure, and weight regulations provides background information on the subject. The report contains a state-of-the-practice description of static weighing techniques currently used in Texas as well as a description of weigh-in-motion (WIM) technology that might be applicable to weight enforcement. The advantages and disadvantages of WIM sorting versus traditional static weighing methods are itemized, and different enforcement techniques are evaluated and compared according to their capabilities, constraints, productivity, safety, accuracy, and applicability. Attention is also given to the relative cost of each method, including initial (equipment and construction) and operating (maintenance and personnel) costs. Also, a description and assessment is presented of the first weigh station in Texas (on Interstate 35 near Devine) that utilizes WIM as a sorting device. This experience, as well as the experience of other states, provides further insight into the ability of a WIM system to aid in truck weight limit enforcement. Major highway trade corridors and potential WIM enforcement sites in Texas are identified. Finally, pavement damage implications on two major NAFTA-traffic highways are examined for hypothetical combinations of enforcement rates, violation rates, traffic growth rates, and the year of NAFTA implementation.
