State departments of transportation (DOTs) have various models for deploying and administering communications infrastructure to support ITS networks, some utilizing public-private partnerships, leasing, asset sharing, resource trading, or other approaches. ENTERPRISE members are interested in reducing costs and improving efficiencies as they administer communications infrastructure. This project is investigating how State DOTs may reduce costs and increase efficiencies for installing and managing infrastructure for multiple, redundant communications networks. The project will gather examples of various communications administration models and document case studies from selected State DOTs.
