ICT Strategy

Intelligent Highways: The right data at the right place at the right

time – all the time.

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.

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.

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.

The Gap:Differing Requirements

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

The Real-Time Enterprise Service Bus

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
