When the scope of a particular corridor study dictates the review and analysis of a relatively large number of road segments along major transportation corridors, the integration of roadway and traffic information in a relational database can produce an effective tool for summarizing corridor attributes, identifying needs and deficiencies, and interfacing with traffic analysis software. Tools for managing and analyzing information support the wide range of decisions that must be made in studies of this nature. The paper describes the application of microcomputers using both generic and applications software in a major corridor planning effort. Microcomputers served as the primary tool for database development and traffic analysis for developing a 20-year improvement program for a 50-mile freeway corridor in Phoenix, Arizona.
