Abstract

Highlights: Implication of Connected Vehicle Technology (CVT) on truck emissions is studied. Study zone is a 30-mile stretch of I-710. Emissions pertaining to CO, NOx, VOC and PM2.5 are evaluated. CVT gives an estimate of the radius of sensor transmission from each truck. There is substantial reduction in emissions with CVT. Abstract: This research aims to understand the implications of Connected Vehicle Technology (CVT) on freight truck emissions – mainly, carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compound (VOC) and fine particulate matter (PM2.5). CVT is associated with communication between trucks and in this paper, it is represented using route connectivity for trucks along a defined length of a freeway. The route connectivity is based on density of freight trucks with sensors exhibiting communication range as discs of known radii. The model is then applied over a 30-mile length of the interstate-710 (I-710) freeway of the Southern California Region to evaluate reductions in emissions. It is found that there is substantial decrease in emissions with decrease in number of trucks used up to establish communication connectivity through sensor transmission along the studied I-710 stretch. In fact, a decrease in emissions is noted with initial increase in sensor transmission radius from 1000 ft to 8000 ft. However, beyond the radius of 9000 ft, emissions reductions become almost constant. These findings can help determine optimum number of connected trucks needed to cause emissions reductions on I-710 (and other freeways) experiencing considerable heavy-duty truck traffic in the United States.
