The primary purpose of this study is to determine what transportation improvements would be needed to accommodate future growth and development of the Raytheon Missile Systems facility located south of Tucson International Airport on Hermans Road. A secondary purpose of this study is to consider longer-term roadway and transit improvements that will improve access to Tucson International Airport and associated airport property planned for future development. Specifically, the study analyzed the effects of closing Hughes Access Road/Alvernon Way to non-Raytheon traffic and recommends alternative roadway improvements that would be needed to accommodate this closure.

This report summarizes the results of a peer review supported by the Travel Model Improvement Program, which is sponsored by FHWA. The peer review of a travel model can serve multiple purposes, including identification of model deficiencies, recommendations for model enhancements, and guidance on model applications. Given the increasing complexities of travel demand forecasting practice and the growing demands by decision-makers for information about policy alternatives, it is essential that travel forecasting practitioners have the opportunity to share experiences and insights. The TMIP supported peer review provides a forum for this knowledge exchange.
