Abstract

The objectives of this research are (1) to assemble and analyze commercial vehicle emission measurement data, (2) classify the effects of vehicle characteristics and traffic activities on commercial vehicle emissions, (3) estimate commercial vehicle emissions statewide in Illinois, and (4) identify truck emission-control strategies with a focus on truck electrification feasibility. The study found that vehicle type, make, age, odometer mileage, fuel type, engine brand (manufacturer), and engine built year are all important factors for truck emissions, and their effects are statistically significant according to ANOVA results. All pollutant emissions (CO, NOx, PM10, PM2.5, CO2) other than CH4 have a downward trend from 2019 to 2021 in Illinois. Such emission trends may be explained by a shift from long-distance truck trips to more regional and local trips between 2019 and 2021. Prolonged journey time due to charging and high initial adoption cost remain deterrents for long-haul e-truck adoption by carriers. Therefore, government policy plays a key role in facilitating electrification.
