Inter-Urban Traffic
Management & Control
(iUTMC)
Next Generation Network
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
are coming…

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, eTolls (Road User Charging).
Growth in road-side and on-road
devices and associated data
volumes.
Drivers for change
• Common 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/CVIS.
• Interoperability
• Need to share information end-to-end, in the new emerging
System of Systems.
• Interoperability is a key enabler to meeting new demands.
Integrated Network
Management
In the UK, there are
152 Local Highway
Authorities (LHAs) and
Other Highway
Authorities (OHA’s),
which include bridge
and tunnel operators,
as well as control
centres in Scotland
Wales and Ireland
where cross-border
issues exist.
Edge-to-Enterprise Integration
Data Distribution Service
(DDS)
The interface between “looselycoupled” independent systems
should not include any systemspecific behaviour or state. It
can include the “data model” of
the information exchanged
between the systems, and the
role played by a system.
Typical DDS application
workflow. Unlike other
publish-subscribe
middleware infrastructure,
DDS has a very strong
emphasis on data modeling.
Peer-to-Peer Architecture
• Applications directly
•
•
•
•
•
•
communicate with each other in a
true peer-to-peer manner.
Messages are not routed through
any intermediate broker, server or
daemon processes.
No external directory service
required.
Built-in discovery service.
Minimises latency and maximises
determinism.
Eases embedding.
Copes with unreliable transport
such as wireless.

Exemplars
• Brisa - Portugal's largest
highway management
concessionaire.
• ITSIBus – an ESB in
production since 2004.
• DDS was selected by the
City of Tokyo’s Metropolitan
Highway Line. They needed
a low maintenance, high
reliability communications
system that was sufficiently
robust for the delivery of
constant updates to their
kiosks.
