This report consists of 9 papers that summarize diesel and hybrid bus models; evaluations of energy and emissions performance for electric rail transit options; predictions from the CAL3QHCR and AERMOD models for highway applications; life-cycle greenhouse gases and energy consumption for material and construction phases of pavement with traffic delay; and modeling the impact of traffic conditions on variability of midblock roadside fine particulate matter. This issue also examines a microscopic transportation emissions model to estimate carbon dioxide emissions on limited-access highways; comparison of fine particulate matter and carbon monoxide exposure concentrations for selected transportation modes; development of a short-duration drive cycle to represent long-term measured drive cycle data; and application of an AIMSUN microsimulation model to estimate emissions on signalized arterial corridors.
