Speed Estimation for Air Quality Analysis

Grants and Contracts Details


The goal of this research is to develop a methodology for speed estimation, applicable in areas without a travel demand model, for the purpose of air quality analysis. A basic understanding of the data requirements of the HERS speed model will be developed. The model will be adapted to Kentucky application based on the data availability. The procedure shall produce average speed estimates for highways in Kentucky by functional class and by time of day at the county level. If sufficient data is not available at the county level, broader regions (of like characteristics) will be defined. To the extent possible, the accuracy and reliability of the model outputs will be evaluated through comparing them against available speed data sources.
