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 Highwaysare coming…

• 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

• 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 “loosely-coupled” independent systems should not include any system-specific 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 strongemphasis 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.
