1. ICT Strategy Intelligent Highways: The right data at the right place at the right time – all the time.

2. Traffic Management With increasing demand for travel, more and more road networks are experiencing Traffic Congestion. In many cases this could be reduced if more real-time information was available to traffic engineers and drivers.

3. Intelligent Highways Intelligent Satellite Navigation re- routing. Automotive developments: Lane Keeping Assist, Adaptive Cruise Control. Cooperative Vehicle Highways Systems (CVHS) will emerge in the next decade. eCall services – activate on impact with airbag systems. Collision avoidance warnings. VMS on the dashboard with optional voice synthesis. High Occupancy Vehicle lanes, e- Tolls (Road User Charging). Growth in road-side and on-road devices and associated data volumes.

4. Drivers for change Shared Operational Picture Increasing need for real-time access to a common operational picture. Increased Data Volumes Real-time dissemination of massive data volumes, often on a large scale. Loosely coupled, Plug & Play Need to cope with emerging ITS demands such as CVHS. Interoperability Need to share information end-to-end, in the new emerging System of Systems. Interoperability is a key enabler to meeting new demands.

8. Data Distribution: Middleware choices Really only three choices: Use proprietary middleware MQ Series, Tibco, BEA Java Messaging Service (JMS) Standards-based Popular in the “Enterprise” domain API only, no wire interoperability Data Distribution Service (DDS) Standards-based Popular in the “Edge” domain

13. DDS Benefits OMG standard - Established since 2003 Fully distributed, Peer-to-peer, Fault tolerant Quality of Service (QoS) per data flow Plug and Play Architecture with dynamic discovery Wire protocol standard (RTPS) Designed for unreliable transports like UDP and wireless networks Scalable, high performance, low latency - 10x faster than JMS
