摘要

Department of Transportation (DOT) requires truck drivers to rest for 10 hours afterrnevery 14 hours of driving. During this time and while waiting for loading and unloadingrnof their trucks, truck drivers idle their engine to provide heat or air conditioning for therncab and sleeping compartment, keep the engine warm during cold climate, and providernelectrical power for their onboard appliances. At large truck stops, 200 or more trucksrnmay be idling at the same time. At these truck stops idling emissions can significantlyrncontribute to the concentrations of NOx and PM2.5 pollutants in the ambient air in thernvicinity of the truck stop. In this study monitoring of ambient air at a large truck stoprnwas performed between mid December 2003 and August 2004. Concentrations of PM2.5rnand NOx were measured continuously at two locations. Computer modeling was alsornperformed using EPA’s ISCST3 model to predict ambient concentrations of PM2.5 andrnNOx at the truck stop. The monitored concentrations of PM2.5, and NOx were thenrncompared to the predicted values in an effort to verify and calibrate the model. Thernmodel can be used to predict the concentrations of pollutants from idling trucks at otherrntruck stops, and rest areas and to identify the extent of PM2.5 “hot-spot” areas near truckrnstops where National Ambient Air Quality Standards may be exceeded.
