Dynamic speed awareness solution installed across six locations on Scotland’s A75

Speed surveys at 12 locations on the A75 Gretna Green to Stranraer road in Scotland, carried out by Clearview Intelligence on behalf of Transport Scotland, found that in some cases speeds were unacceptably high, particularly with heavy goods vehicles.

Speed surveys at 12 locations on the A75 Gretna Green to Stranraer road in Scotland, carried out by Clearview Intelligence on behalf of 505 Transport Scotland, found that in some cases speeds were unacceptably high, particularly with heavy goods vehicles.


Working with the road operator, Scotland TranServ, Clearview developed a vehicle activated, dynamic speed warning system to provide a highly visible and immediate reminder to drivers to monitor and manage their speeds appropriate to the legal limit of their vehicle’s classification. The solution recognises the road has differing speed limits per vehicle classification and so is designed to identify instances of speeding per vehicle type and provide an alert to the driver. Six locations were selected for maximum impact.

Clearview installed solar powered vehicle detection count and classify units to record a combination of vehicle classification with identification of vehicles travelling above the speed limit. Each of the six sites features two vehicle activated signs (VAS) facing each direction of travel. The vehicle detection units communicate with the VAS to trigger a display showing the appropriate speed limit warning according to vehicle type.

    The Netherlands has been looking at incentivising rush-hour avoidance. The intention is to better understand road users' motivations and find alternatives to congestion charging. Something significant needs to happen if we are to adequately address the traffic congestion and other issues caused by the ever-rising numbers of vehicles on our roads. Congestion or distance-based charging is seen as one way of managing demand and raising revenue for improvements to transport infrastructure. However, charging is

    A fledgling advanced lane management assist system can take the guesswork out of selecting the right lane on a congested freeway, as its inventor Robert Gordon explains. As drivers we’ve all done it and control room staff see it all the time – motorists on congested freeways switching into what they perceive is a faster lane, only to come to a halt a few moments later and watch vehicles in the other lanes continue to move past. Now, by re-analysing readily available data in an advanced lane management as

    New safety technologies could play a major role in reducing the numbers killed on European motorways, according to the European Transport Safety Council (ETSC), in a new report published today. The new analysis of developments in motorway safety shows that, despite recent progress, around 1,900 were killed on motorways in the EU in 2013. The report cites figures from several countries showing that up to 60 per cent of those killed in motorway collisions were not wearing a seatbelt. It calls on the EU to req
