    Objective: This research intends to explore the correlation between pavement roughness and vehicle emissions, and classify the pavement roughness based on vehicle emissions and public health impacts. Method: On-road tests were conducted to measure vehicle emissions by a Portable Emission Measurement System (PEMS), and collect the corresponding pavement roughness by a smartphone application. A total of 19,038 data pairs were collected during 325 km long test routes in the State of Texas. The correlation of the emissions and International Roughness Index (IRI) are analyzed and the roughness was classified into clusters by three pattern recognition algorithms.  Findings: The pavement roughness could be classified into four categories based on the clustering features of emission factors. The average of Normalized Emissi.. View More»
