The goal of this research project was to investigate two short term issues currently faced by the Pennsylvania Department of Transportation (PennDOT) relative to their statewide traffic counting program. (1) PennDOT operates 63 Automatic Traffic Records (ATR) that are used to calculate adjustment factors to estimate Annual Average Daily Traffic (AADT) from short term counts. The monthly adjustment factors calculated from the 1998 and 1999 data were tested using statistical analysis to determine their statistical significance and short term strategies to improve the effectiveness of the program; (2) PennDOT also uses the ATR data along with other short term counts to calculate annual growth factors for various functional classes and regions across the state. Statistical analysis of this program was conducted to determine its overall quality and to recommend short term improvements.
