"Pedestrians in carriageway" always makes me chuckle, for some reason I picture a broken down bus with people wandering all over the road because they've "escaped" like animals.

But I've also had my fair share of stupid ones, I still don't get the "X Mins to Jct 11 for X" ones, is it meant to be a challenge?

No, informative, so you can see if you're on schedule or not.

I passed one today that read as follows

COULD YOU REDUCE YOUR CARBON EMISSIONS

This is possibly the most useless one I've ever seen. Not even "Reduce speed to save carbon" or anything practical. It was a question, sans question mark, with no answer. Utterly useless.

From what I was told while at an interview once they are outsourced mainly to Serco. (this was an interview for Serco so he may have been making things up and was nearly 10 years ago). It was a boring job with them to collect data from land owners and councils to help with the administration of extreme / dangerous loads. I was told they had to get the permission of each land owner separately before they could pass through the land. Serco were creating a system to make this easier but they needed information on things like bridges and load information on various parts of the network. (I didn't take it when offered to me)

From what I was told there are 3 main ways of activating them
1. Automatically: there are lots of sensors in the road and they look at average speed over them and volume of traffic. This turns on the "Caution Queue" and the variable speed limits etc. they are also on slip roads and warn about queues on there. I used to think the road sensors were based on weight but I was told they are magnetic.

2. Manually: the highways agency/ police can request them to be turned on for things like accidents and diversions.

3. Information: This is for things like events or planned closures or just things like "don't drive tired" before the services.

from what I can gather its a pretty decent system and is more advanced in the south.

Edit:
cdd: Will have to have a look at that as it seems quite interesting and seems to confirm some of what I was told. (I am such a sad git, I love infrastructure things)
