EXPLORATORY ANALYSIS : A METHOD TO IMPROVE THE LINK BETWEEN TRAVEL DEMAND MODEL AND DTIM2

This report addresses the relationship between a traditional travel demand model (TDM) and the Direct Travel Impact Model (DTIM2). It focuses on improving the estimation of gridded, hourly emission inventories using TDM simulation outputs. The report explicitly defines the links between TDM and air emission models. A statistical model is developed that expresses the relationship between hourly traffic counts and TDM simulation volumes by trip purpose. Finally it propose and tests a method for allocating TDM assignments into hourly breakdowns by trip purpose.
