This paper describes the ROMANSE (ROad MANagement System for Europe) project and the integration of some of its applications. It is based on the City of Southampton and the surrounding area in Hampshire, England. The system and its applications can be viewed as one entity, connected to the outside world through `terminators', each of which defines a functionality to be provided by the outside world, and data that are expected to be received and/or provided. ROMANSE has 19 terminators of three types: humans, systems, and environment. Its functional architecture defines its system functionality, and its functions and subfunctions are grouped to form 17 applications in the physical architecture; each application performs a different set of functions. ROMANSE has two methods of integrating applications within a system. The first method is to combine several applications to form a new single application, and is good when large amounts of data are passed between the applications. The second method makes operator interfaces for several applications available through one terminal, and requires that the applications have the same type of operator interface, or interfaces that can be run on the same hardware and software platform. Both these methods are used in the ROMANSE project.
