Travel demand forecasting models are used to predict future traffic volumes to evaluate roadway improvement alternatives. Each of the metropolitan planning organizations (MPO) in Alabama maintains a travel demand model to support planning efforts. For smaller areas, non- MPOs, no travel demand models exist to support planning efforts. The goal of this project is to examine the use of a methodology that can utilize existing traffic counts to develop origin/destination matrices in an attempt to improve existing travel demand models and support the development of new travel demand models in areas that are too small to maintain their own models. Applying the methodology to develop the origin/destination matrix for a community from existing traffic counts has the potential to be used to evaluate area friction factors, be used to support the development/refinement of trip generation models and determine the level of external-internal and external-external traffic.
