Cel
Traffic managers in Europe face the problem of protecting their investments in telematics infrastructure. Using new applications or even introducing new features to existing systems very frequently forces traffic authorities to make - once more - new investments and replace legacy infrastructure, in many cases while it is still fully operational. OMNI will address this problem by facilitating the re-use of legacy infrastructure by new transport telematics applications. To that end, the project will develop a network-wide, intersection-driven transport management model. The model will act as an intermediate layer that isolates the actual network infrastructure from the applications that are using it. The project will model the existing components in the network considering both their physical characteristics and their functionality. The model will present standard interfaces to the objects of the network, allowing the integration of advanced telematics applications or new devices in a pre-existing network infrastructure. The model will be implemented in the form of two prototypes composed by a set of technical specifications and a software product for exploitation.

The project will also involve research activities in a number of transport telematics application areas (advanced traffic control systems, automatic incident detection and end user information via the WWW) as well as video-based sensors for surveillance and traffic management. This will allow, on the one hand, achieving additional performance in these application areas and, on the other hand, using these telematics applications and devices as test cases to evaluate the performance of the OMNI model. The final prototype will be evaluated in four pilot sites. The different traffic infrastructures and user requirements of these sites will validate the openness of the model, and the use of different traffic management architectures (centralised, distributed) will validate Traffic managers in Europe face the problem of protecting their investments in telematics infrastructure.

OBJECTIVES
Developing a network-wide, intersection driven model: this will act as an intermediate layer which isolates the actual network infrastructure. OMNI will model the components existing in the network (sensors, lanes, local controllers, considering both their physical characteristics and their functionality. The building blocks of this model will be individual heterogeneous intersections.
Demonstrating this model in two prototypes, which will be composed by a set of technical specifications and a software product for exploitation.
Building a consistent view of all the diverse intersections forming the network and their related traffic components and a smart integration of different applications and devices in pre-existing network infrastructures. It will also address testing the flexibility of the model by the integration within a number of traffic networks using advanced video-based sensors for surveillance and traffic control. There will a set of transport telematics applications, namely surveillance, advanced traffic control systems, and end-user transport information on the web.
Testing the openness of the model with respect to diverse user requirements and traffic infrastructures in four test sites: Alicante, Milano, Chania and a virtual test site in Paris.
DESCRIPTION OF WORK
The work will begin with the review of the state-of-the-art. Relevant users will be identified and classified and a questionnaire will be distributed among them in order to extract relevant information about their main needs and requirements. Local authorities, traffic systems manufacturers, traffic operators and end users (drivers) will be contacted, when possible meetings with these users will be conducted in order to get a more complete appreciation of their needs. The main system requirements and socio-economic constraints will be extracted as conclusions from both user requirements and current system capabilities. The task will also define preliminary methods and indicators for the evaluation of the system. User requirements will then be translated into technical specifications of the system as a whole and of the individual modules. An accurate analysis of the evidenced user needs and system requirements will be the next step. The final result will be a system architecture design that uses the UML Methodology. The development of the project's first prototype will be done on the basis of the previous analysis and design work already mentioned. This comprises the implementation and integration of all project modules. An evaluation plan will define the evaluation methodology to be used in the project. The development of the first prototype will be tested in laboratory. Issues such as the integration of modules, the compliance of the operation of the system with the technical specifications, the reliability, communications, etc, will be assessed. On the basis of the first prototype, the project's final prototype will be implemented: specific developments will be made in each evaluation site, in order to adapt the system to the site characteristics and to enable its further installation and evaluation.
At the end of the project, the main conclusion is that the OMNI MOUN is able to model the topology and traffic management infrastructures of any European city as demonstrated. No changes on the current architectures, infrastructures and devices have been necessary to use OMNI in four different sites. In addition to the configuration of the logical representation of the physical infrastructures, the only one requirement to use OMNI is to implement the necessary interfaces for making the different components OMNI compliant. These interfaces are small pieces of software to be implemented by the components providers. Guidelines to do this have been produced and successfully applied in each site. The approach used by the OMNI model allows to connect and inter-operate existing devices and applications by mean of developing software interfaces towards the model. At the same time the model provides for a system independent interface to expose data and functionalities to new applications (i.e. advanced control systems, information systems). The demonstration pilots have demonstrated the feasibility and effectiveness of this approach. Based on COM technologies, the technological approach followed for the implementation of the OMNI model facilitates the adoption of standard communication protocols; independence from operating systems; high level of scalability, and a distributed architecture.
