18. ITSIBus and SOA
Uses an Enterprise Service Bus (ESB) for integration middleware – in production since 2004.
Everything as a service
A functional component in ITSIBus is always a service
A service implements an open interface and generates subscribe-able events (by other services)
• Services run on Systems
Systems are service execution containers offering core services for common functions (e.g. security, management, monitoring)
• Services are available from multiple technologies
Being standard, services can be called from different technologies.

21. Intelligent Highways Infrastructure
Adopts Portuguese ESB model as an exemplar.
Federated ESB approach fits with OGD and EU developments – Defra (INSPIRE), Police (ISS4PS), Customs & Excise (XSIZE), etc.

22. Legacy Integration
Smart endpoints provide an abstraction layer for “Encapsulation”:
Java, C++, DCOM, CORBA
Adapters (e.g. JCA – J2EE Connector Architecture)

23. Conclusions
The Intelligent Highways Infrastructure requires future-proofed ESB Endpoints which need to include RSU’s that can accommodate:
Legacy transponders
3GRSE-based Data Hubs
CVHS-based Roadside Gateways
These need to be based on:
Industry standards (e.g. UTMC/Datex II)
Ruggedised PC hardware
IPv6 network interfaces/addressing
