ICT Strategy

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.

Data DistributionMiddleware 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

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
