Title: Operational and Emission Analyses of Roundabouts under Varied Vehicle and Pedestrian Demands

Date:

Status: Current

Summary: The additional funds will be utilized to support a graduate student for a year to expand the scope of the project. It will also be used for the student to travel to one conference to present the results of the study. In particular, we plan to utilize a GHG monitor (Picarro G2301 Cavity Ring-Down Spectrometer) that the Pioneer Valley Planning Commission owns and is willing to provide. This monitor collects precise measurements of water vapor, carbon dioxide, and methane. For the purpose of this project we will utilize it to measure GHG emission levels at the campus roundabout. We will then compare those levels with the ones obtained from the Comprehensive Modal Emissions Model (CMEM) that utilizes vehicle trajectories collected in the field as input. Dispersion models will also be used to compare pedestrian exposure to GHGs as measured from the monitor vs estimated through CMEM.
