TTM10 Intelligent Transport Systems

• Intelligent Transport Systems (ITS) is the use of ICT for more

safe, efficient and environmental-friendly transport and traffic

solutions.

New theme started

fall 2011

TTM10 Intelligent Transport Systems

• Content

– Communication solutions: to ensure continuously connected vehicles

over the best/preferred air interface available.

– ITS applications: aim to make the transportation network more safe and

efficient for road users while also focusing on the environmental impact.

Includes also value-added service like point of interests applications.

– Supporting facilities: include positioning and location referencing,

execution environments, and security in ITS

• Recommended background

– TTM4100 Communication Services and Networks

– TTM4105 Access and Transport Networks
