Variable speed limit signs now active between Craigellachie and Revelstoke are intended to reduce the frequency of weather-related motor-vehicle collisions.
Eighteen variable speed signs have been activated on the Trans-Canada Highway on an estimated 40-kilometre section from the Perry River Bridge to Revelstoke.
Weather conditions can change rapidly on this section of Highway 1 and the signs will require drivers to slow down when conditions deteriorate, says Shuswap MLA Greg Kyllo in a June 2 news release.
“Statistics show seven out of 10 speed-related crashes in B.C. are caused by people driving too fast for road conditions,” said Kyllo. “The state of road conditions in our region’s mountainous terrain can be unpredictable, but these new signs will give drivers up-to-date information on what’s happening up ahead, which improves safety for everyone on the road.”
The electronic signs will adjust the speed limit, requiring drivers to slow down during inclement weather.
The digital signs will be very visible to drivers, and the speed limit will be changed to reflect driving conditions. Overhead message signs at the entrance of each corridor will inform drivers to be aware of changing weather conditions.
Whether it is extreme cold, freezing rain or heavy snowfall, the extensive system of traffic, pavement and visibility sensors will be calibrated to detect the conditions and provide a recommended speed to operations staff. This information will be used to continuously update the speed shown on digital signs, to help drivers know the maximum safe driving speed during adverse weather conditions, Kyllo said.
This project is part of B.C. on the Move, the B.C. government’s 10-year plan for the improvement of the province’s transportation network.
