TMC Query

CFS75 · 19th August 2007, 13:46

Can anyone suggest a link for information about TMC?

I use TMC on my Satnav but would like to know more about the system - how is the data collected, collated, transmitted and by whom?

This will give you a good overview to start with.

A private company iTIS Holdings provides a commercial TMC service iTMC in the United Kingdom. It is broadcast nationally on Classic FM. The price of the service can be included in the price of the car or of the navigation system. This system uses traffic data collected from sensors installed on fleet vehicles known as a Floating Vehicle Data system consisting of approximately 50,000 vehicles. Eddie Stobart haulage have this system installed within 750 vehicles, AA Patrol 3,800, and National Express 530.

RAC Live operated by RAC Trafficmaster Telematics (RTT) a 50-50 joint venture between RAC Motoring Services and Trafficmaster also operates a national service. It uses 3 commercial radio broadcasters, GWR, Capital radio and Chrysalis who together ensure reception across mainland Britain. This system uses a road side infrastucture to measures a vehicle's travel time between sensors placed a few miles apart, and uses number plate recognition technology.

Both providers are responsible for their own location tables. The current location table version of ITIS is 5.1. The current location table version of Trafficmaster is 2.0.

Within the United Kingdom TMC services are only offered as pay services. As such they are currently always carried by commercial radio stations rather than by the BBC, a public service broadcaster. The BBC is required by its charter to be free from both political and commercial influence and is therefore unable to carry a pay service unavailable to all.

Thanks GG the link is interesting but I really wanted basic general information about the system.

Who provides the camera equipment? Who pays for what? Is there a national organisation involved? How about roads not covered by the cameras? How does the radio coverage operate? Do all radio stations carry the signal?

If you can provide any other links or sources it would help to satisfy my curiosity!

Kandyman,

Thanks for the information. Just what I was looking for. I wondered why I was only getting a signal from commercial stations.

Your explanation is much clearer and easier to understand than the information in the link!!

Kandyman,

I got there via google in the end! Eventually I found the Traffic Master Channel (Wikipedia) with all the information in a readable format.

There are times when I require a satnav to navigate google!
