BMW First In The UK To Offer Full Colour Screen Satellite Navigation With Dynamic Traffic Information
Published: 18th March 2002
Integrated with the satellite navigation system, warning symbols are displayed on a full colour screen map enabling the driver to see where traffic problems are located. By selecting the traffic information screen the driver can then access a detailed list of messages showing information on the exact location of the delay, the length of the tail back and the cause of the problem. For example a detailed message might read as follows:
- M5: Birmingham (West) & Quinton to Frankley Services
- Accident. Carriageway reduced to one lane
- Length 1.5 miles
If a final destination has been entered and a route selected, the system will offer to re-route the driver. The driver will be alerted via voice and screen messages in red on the navigation map. If the driver feels that the cause of the delay will make re-routing unnecessary, he can continue on the original course.
If a final destination has not been entered into the navigation, the system will give advance visual warnings to the driver of any delay along the route. Dynamic Traffic Information has the capacity to pick up accurate warning messages within a two hundred mile radius of the location of the car.
How the system works?
The system used is called TMC (Traffic Message Channel) and is operated
in the UK by ITIS. This organisation collates traffic information from
regional traffic control centres throughout the UK as well as using an
advanced traffic collection system known as Floating Vehicle Data or FVD.
This system collects speed and congestion information from thousands
of vehicles travelling on the road network. The traffic data is then broadcast
on FM radio (Classic FM) as a "silent" sub channel. Once received
and decoded the messages are integrated into the navigation system to
provide the driver with verbal and visual warnings. The result is a system
that provides accurate, detailed and timely traffic alerts ensuring the
driver is aware of problems well in advance of reaching them.
