The British Columbia government in Canada has deployed variable speed limit signs along three highways in the province, Highway 99, Highway 5,  and Highway 1, which are prone to rapidly changing weather..Variable speed limit signs display the legal speed limit when road and weather conditions change.

From 2 June, motorists are required to obey the signs, which are regulatory and enforced by the police.

Static message signs at the entrance to each corridor inform travellers they are entering a variable speed zone. A digital message sign (DMS) at the beginning of each corridor warns drivers of changing weather conditions. Flashing lights installed above each variable speed limit sign are activated when a reduced speed limit is in effect.

Traffic, road and visibility sensors monitor real-time traffic speeds as well as road and weather conditions to provide recommended reduced speeds back to operations staff who then adjust the electronic signs to let drivers know what speed they should be travelling for the current conditions.

Webcams installed along each of the routes monitor traffic and weather conditions to provide drivers and operators at the Regional Transportation Management with real time information on conditions along the routes.

    The in-house winter maintenance and vehicle tracking system built by the Public Works Department in Hartford, Connecticut, coped with record snowfalls and cut costs too. When it comes to dealing with the effects of mother nature, transport agencies can find themselves in a lose-lose situation: criticised if the roads or rail lines are disrupted by snow, ice or floods for more than a few hours and lambasted for wasting money if the equipment and stockpiles put in place for a hard winter remain unused.

    While The Netherlands already has some of the safest roads in the world it has ambitious plans to make them safer still, as Jon Masters discovers. In virtually all periodical studies and comparisons of countries’ road safety performance, the Netherlands is consistently in the top three and often leads the world, depending on how casualty figures are compared. According to the International Traffic Safety Data & Analysis Group (IRTAD) of the International Transport Forum, road deaths per capita have falle

    The adaptation of machine vision to transport applications continues apace. That the machine vision industry is taking traffic installations seriously is evident by the amount of hardware and software products tailor-made for ITS applications that are now available on the market. A good example comes from US-based Gridsmart Technologies which has developed a single wire fisheye camera that provides a horizon to horizon view for use at intersections. Not only does the single camera replace four or more in a
