This paper presents a methodology to quantify the impact of roadway conditions on vehicular emissions. The amount and type of Green House Gas (GHG) emissions generated by vehicles depend on factors such as vehicle type, air temperature, vehicle age, fuel type, and vehicle speed. The assumption is that better pavement condition, in particular lower roughness due to good maintenance practices, reduces fuel consumption and corresponding emissions. For the purpose of comparison, roughness is measured directly with a laser profiler, retrieved from a Pavement Management Information System (PMIS), and obtained with a Roadroid Mobile Phone Application. A portable Emission Measurement System (PEMS) is used to measure gas emissions on pavement sections. Statistical analyses are performed to investigate the relationship between pavement roughness and gas emissions. The preliminary results of the study shows a good correlation between roughness and vehicular emissions, but more data are needed to confirm that better pavements will generate lower gas emissions.
