Does anyone know what the criteria is for deciding what roads appear with RTTI?

I can see no logic in which roads are included and which aren't. For instance, on my daily route to work, about 50% of the route is populated (all the roads are major A Roads) but the biggest and most important trunk road is totally missing from the RTTI. Why?

I've noticed this a fair bit; Seems quite a few major roads are missing......

I'd be interested to know the answer to this too...I can't workout the logic either???

So they use our mobile phones to track how fast we have moved along a 500m section and average/ aggrigate the data back into the network?

This is a bit spookey!

Well they obviously don't use Vodafone.....since December my in car network coverage has been really poor.

Good job really as last night the A421 would have been flowing 'very freely'

Same here! Since they started rolling out 4G, their roaming coverage has been absolutely terrible... Do you often get cut off mid-call when in the car??

I nice steady 70mph of course.

I'm very disappointed with the traffic data in my car, as it is very misleading. Most times roads that are shown in red are actually flowing perfectly well. I've now gone back to using my TomTom with HD traffic, which is excellent. Very accurate and shows almost all of the roads whereas BMW's RTTI sows less than 25%.

+1 for Tomtom HD traffic! It uses Vodafone for it i believe.
