Description:
Vehicle-related air pollution has an intrinsically dynamic nature. Recent field measurements and modeling work have demonstrated that near-road topography may modify levels of air pollutants reaching populations residing and working in close proximity to roadways. However, the majority of field measurements characterizing roadway pollution have historically relied on fixed-point roadside monitors in areas with free-flowing terrain. Mobile monitoring is a potentially powerful and cost-effective method to capture the impacts of near-road topography on vehicle-produced air pollutants by rapidly collecting location-resolved air pollutant measurements alongside roadways and surrounding structures. In order to augment existing fixed-point ambient monitoring with higher spatial-resolution measurements, a zero-emissions electric vehicle has been equipped for use as a mobile monitoring platform. Results from pilot mobile monitoring of ultra fine particles and carbon monoxide near a major highway (1-85) in Durham, North Carolina using the GMAP electric vehicle are presented.
