Recently we got a changeable message sign in London... one of the few existing outside of the Greater Golden Horseshoe (Metro Toronto).

That's like northern Alberta between Donnelly Corner to Valleyview. Dead straight between the two locations, with the exception of the crossing of the Little Smokey River. Then it's a right curve down the hill to the bridge and a left uphill. Posted limit on the straight stretches: 100 km/h The hills and bridge: 90 km/h. Drive you nuts when it takes 45 min for the headlights on the horizon to actually pass you.

All of the above in BC, plus on asking if your campfire is out. (And according to a friend with the BC Forest Service, the answer is all to often "no" )

BC doesn't have much for Variable Message Signs, other than what TheCat has said, in addition to the campfire one. The only other ones are the portable ones used at road works.

Electronic speed signs are popping up all over the Seattle/Bellevue area. Perhaps someone with pics could post. Seattle, and I believe Minneapolis are leading the US with this technology. There may be others.

How do you post pictures again? I have not done this in a while and would have posted pictures so instead you can go to the Dept. of Transportation website to see pictures.

When traffic is flowing normally, the overhead signs are blank and the normal 60 mph speed limit is displayed in either side of the sign bridge.


When traffic up the highway begins to slow down, overhead signs automatically reduce the speed limit to prepare drivers for slower traffic ahead, reducing sudden braking and collisions. Message signs offer instant traffic information, such as congestion or blocking incidents as they happen miles up the road.


The overhead speed-limit displays switch intermittently to directional arrows, and a traffic information sign warns of a lane closure ahead.


The speed limit automatically drops even more as traffic gets heavier.


At the point of a blocking incident, such as a collision or a stall, red X's indicate which lanes are closed. Meanwhile, the speed limit automatically increases as traffic returns to normal.

It's funny though, we had this system in the Netherlands since the 1970's, and now 35 years later the Seattlites copied it.

I think its a spin on an established concept in that these signs are placed relatively close together so that you have a complete sign cluster every 500 ft or 152 meters. The purpose is to provide more "real time" traffic response when traversing heavily used corridors.

It is vital that these active traffic management gantries are not placed too far from each other, say no more than 600 m or 2,000 ft, so you always have one or two within visible range. Otherwise it doesn't work as well. In some countries they place them 2 km apart, which means if a 50 mph limit is shown, it takes 1.5 minute before you can see the next sign. Traffic has changed since then, especially on motorways with a high degree of saturation. Sometimes a traffic jam grows 1 kilometer per minute.

So funny, because a 90 km/h limit due to smog is completely useless. Smog usually does not last more than a few days, and a temporary 90 km/h limit doesn't change that. It takes more than a couple of days before you have a statistically significant, if any, reduction of smog.

I know, and we only have smog when the wind comes from the east so the pollution of the Rurh area drifts in our direction, so what can we do about it?
It's useless indeed.

Traffic guidance.

The downside of VMS's here in Europe is that foreigners can't make squat of them...

Well, even as someone who can read Dutch, with an occasional assist on vocabulary (bedankt, Chris), what does "traffic guidance in the Ghent area starting November 19" mean? Are they warning about electronically-posted detours or something?

Some countries are better at this than others (like "Men at work" in Italy, even though there doesn't seem to be any actual men at work most of the time), and some have large boards with lots of room that display messages in 3 or 4 languages at the time.. Like that sign in Belgium, which doesn't even have French..
It would be illegal to have French on a sign in that part of Belgium. Refraining from comment on whether that makes sense....
