Significance Analysis of Vehicle Operation Modes for Pollutant Emission at a Signalized Intersection

In this paper, we developed vehicle emissions models as a function of the five operation modes of vehicles at a signalized intersection. Using VISSIM simulation software, second-by-second running activities data of the vehicles were generated for a signalized intersection. The outputs from VISSIM include were used to identify the operation modes of the vehicles and used as input into the EPA emissions model MOVES. The emissions CO was estimated on hourly level. Finally, based on the obtained operation mode data, CO pollutant emission regression model was established. The model also indicate the significance of the operation modes on the CO emission and provides a basis for understanding the contribution of the operation mode on pollutant emissions.
