Over the past two decades, technological innovations in highway transportation industries and intermodalism in the freight industry reshaped the American transportation system. The State of New Jersey, located between two major metropolitan centers in the Northeast Region, Philadelphia and New York City, has a transportation system that carries high volumes of interstate traffic and products. Furthermore, traffic patterns in the State of New Jersey vary significantly from North to South and from rural to urban areas. The tremendous demand for transportation services today imposed significant impact on its infrastructures and highways. Thus, it is important to characterize the truck traffic in New Jersey and evaluate its impact on the critical infrastructure. There are a total of more than 90 permanent Weigh-in-Motion (WIM) sites operated by NJDOT. These WIM sites are spread across the State of New Jersey and located at different inter-state and state highways as well as local roads.

In this study, the research is aimed at characterizing the truck traffic in New Jersey based on 20 years of truck weight data collected from these WIM sites. Twenty years of WIM data were processed using a customized computer program to separate regular truck traffic and over-weight truck traffic. The characteristics of truck traffic were studied according to classification, number of axles, regions, road types, regular or over-weight truck.
