Characterization of Potential Impact of Speed Limit Enforcement on Emissions Reduction
The main objectives of this paper are twofold; first, the paper presents an approach to combine field data and microscopic emissions modeling to answer a transportation air quality policy issue. The study then uses this approach to evaluate the potential benefits of speed limit enforcement on vehicle emissions on high-speed roads. The analytical approach used for this investigation involved performing two parallel phases - a field analysis phase based on field collected GPS data and a modeling analysis based on MOVES default drive schedules. Two highway speed limits were included in the analysis. The results show a modest increase of CO2 and fuel consumption for both speed limits. NOx and THC were increased more than 10% as the result of exceeding the speed limit. PM2.5 also showed a sizeable increase in the range of 10% to 36%. With an average increase of approximately 50%, CO showed the highest increase among all the pollutants.
