THE ITSIBUS APPROACHPortuguese Integration Model
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.

HA TO-BE ARCHITECTUREStrategic implications
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.
Legacy Integration
• Smart endpoints provide an abstraction layer for “Encapsulation”:
• Java, C++, DCOM, CORBA• Adapters (e.g. JCA – J2EE Connector Architecture)
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
