A DATABASE MANAGEMENT SYSTEM FOR TRAFFIC ENGINEERING DEPARTMENTS OF SMALL AND MEDIUM-SIZED CITIES

This report begins with a summary of the information needs of municipal traffic engineers, and discusses the problems and limitations of traffic information data base management systems (dbms's) currently in use. A proposed dbms is described based on dbase III plus which includes an integrated urban data bank and three types of software for information systems management, information retrieval and interfaces with application programs. Two general categories of data are included: those related to intersections and those related to street segments. A sector of the city of Quebec was used to test the feasibility of the system. Although limited, the use of the data shows that the proposed system has distinct advantages over existing systems, and is likely to become even more attractive as cheaper, more powerful and more versatile micro-computers enter the market.
