This report outlines the research and work performed to lay the foundation for the development of a New Jersey Interagency Emergency Management Plan. The research into existing practices within the four state level transportation agencies reveals that the agencies continue to practice silo style management to operate the state roadway network. Ineragency communications is minimal and lacks protocols. The agencies operate individual roadways but fail to operate the road network. A new paradigm to operate the road network is warranted. Agencies must consider the impacts on other roadways prior to taking action. Real time communications and interagency coordination would enhance operation along the routes.
