  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.

  5. Life at the Edge: Traffic Management Example

  6. The Gap:Differing Requirements

  7. 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

  8. DDS Applicability

  9. Global Data Space –Publish & Subscribe

  10. DDS Class Diagram

  11. The Real-Time Enterprise Service Bus

  12. 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

  13. References – next steps • “Using DDS to Enable The Real-Time Enterprise Service Bus (RT-ESB)”, Rajive Joshi, Ph. D., Gerardo Pardo-Castellote, Ph.D., Real-Time Innovations, Inc. • “OpenSplice DDS in Transportation”, Dr. Angelo Corsaro, PrismTech Ltd.OMG's Data Distribution Service Standard: An overview for real-time systems” Rajive Joshi and Gerardo Pardo-Castellote, Dr Dobbs Journal, November 20, 2006. • OMG Data Distribution Portal • Next steps: validate with the Market/Industry.
