The Iowa Traffic Analysis Model (ITRAM): Collaborative Statewide Model Architecture and Realization

In 2006, the Iowa Department of Transportation launched an effort to design and build a statewide travel model known as iTRAM (Iowa Traffic Analysis Model). The effort was organized such that all the stakeholders' needs could be integrated in the final product. The initiative had two phases. The first phase was a set of listening and education sessions aimed at first illustrating what a model of this nature can do and secondly finding out what Iowa wanted in a statewide model. These needs were balanced with the typical components of statewide models and summarized in a document called "Model Architecture" which was then used to estimate the time and resources needed to build the model itself. The second phase was the actual building of the specified statewide model. Collaboration took the form of concept development, technical strategic planning and manual labor. Collaborative technical work has a number of advantages over other work styles. Among the advantages are: (1) Creating an environment of involvement with executive, technical, engineering, planning, and research expertise all close at hand. (2) Building a forum for problem solving at all levels of model construction thus saving scarce resources. (3) Enhancing in-house knowledge by including the end users in each step. (4) Ensuring that diverse travel model elements such as the energy, economic, or agricultural impacts on statewide traffic can be captured.
