This paper presents the MOTOS (Management Of Traffic in Open Systems) project, running from January 1993 to March 1995, that has been supported by the UK's Department of Trade and Industry (DTI). MOTOS aims to: (1) contribute to the open systems standardisation process; (2) investigate the impact of real-time data on an open systems architecture; (3) demonstrate the interworking of different databases; and (4) prove its enabling technologies with a pilot demonstrator project. The pilot demonstrator used the ARC/INFO Geographical Information System (GIS) to: (1) manage and display traffic monitoring data; and (2) control traffic management functions developed in MOTOS. The paper describes the MOTOS enabling technologies: (1) the ANSA systems architecture; (2) the DIOMEDES distributed, replicated, real-time database; and (3) the ARC/INFO GIS. The M2/M20 corridor in Kent, England was chosen as the study area for the MOTOS project, using traffic flow data from both urban and interurban sources to provide strategic traffic management data for the whole area. The corridor is also a main route to the Channel Tunnel. The project successfully demonstrated the use of both open systems and GIS techniques for traffic monitoring and management.
