The passage of the new Clean Air Act and the Intermodal Surface Transportation Efficiency Act calls for more cooperation between developers and transportation professionals to move new transportation projects from design to implementation. In response to this need for cooperation between different levels of governments, developers and transportation professionals, the authors have developed a set of procedures within which a traffic impact study can be formulated.1,2 At the heart of these procedures is the determination of the scope of a traffic impact study for a proposed site.
