AN INTEGRATED SYSTEMS DESIGN APPROACH FOR TRAFFIC CONTROL AND SURVEILLANCE

摘要

This paper describes the integrated approach adopted for use in the design of the Traffic Control andrnSurveillance Systems (TCSS) for the Tsing Ma Control Area, Western Harbour Crossing and Route 3rnCountry Park Section. The Tsing Ma Control Area, which includes the Lantau Fixed Crossing and thernCheung Ching Tunnel, and the Western Harbour Crossing are part of the Hong Kong’s Airport CorernProgramme which is currently one of the world’s largest infrastructure programmes under construction. Uponrncompletion in 1997, they will provide the crucial links from Kowloon Peninsula and Hong Kong Island tornthe new airport at Chek Lap Kok.rnIn the design of the TCSS, integration of the traffic controller’s operating procedures and integration of thernsystem components are two important design considerations. Integration from the traffic controller’srnperspective consists of the ability to control and monitor the traffic operations from any workstation, andrnperform any function with a consistent and intuitive interface. Integration from the implementor’srnperspective is the ability to incorporate a wide variety of field equipment from different suppliers into arncohesive system, and to easily and rationally interface with adjacent and related TCSS. These objectives arernbeing met through the adoption of a structured design approach which endorses “open system” concepts and arnPOSIX (Portable Operating System Interface Exchange) compliant operating system, a distributedrnarchitecture, the use of flexible software development tools and a wide area communications system whichrnsupports local area network (LAN) communication standards. This has resulted in systems which providernintegrated operations and can easily be expanded both functionally and geographically.
