An Investigation on Commercial Motor Vehicles in New Jersey

Abstract: The increasing presence of commercial motor vehicles (CMVs) on roadways, driven by the rapid growth of e-commerce, has led to a significant rise in large-truck crashes, with some resulting in serious injuries or fatalities. This study aims to thoroughly investigate the factors contributing to CMV crashes in New Jersey and to develop targeted countermeasures that address these issues. By analyzing data from the Federal Motor Carrier Safety Administration (FMCSA), the study compares New Jersey's CMV crash trends with national patterns, identifying several unique state-specific factors that influence crash rates. These factors include the presence and design of medians, the diversity in driver license classifications, the visibility and accuracy of hazardous material signage, seatbelt usage rates, and the frequency of traffic violations among CMV drivers. The study's findings led to the proposal of a range of tailored countermeasures, such as installing rumble strips and barriers to improve median safety, implementing targeted safety management strategies for different driver license categories, and upgrading hazardous material signage for better compliance and visibility. Additionally, the study emphasizes the importance of safety education programs focused on seatbelt use and responsible alcohol consumption, the optimization of road conditions through measures like delineators and variable speed limits, and stricter enforcement of seatbelt laws and traffic regulations. By addressing these factors, the proposed countermeasures aim to reduce crash rates, enhance road safety for all users, and create a safer environment for both CMV operators and the general public on New Jersey's roadways.
