Calgary pioneer VATCS in Alberta
Unipart Dorman are delighted to announce that after much considered research the City of Calgary have selected to trial the VATCS traffic calming technology.
Bruce McDougal M.A . Transportation planner at the City was looking for a display based technology with a proven traffic calming background in maintaining long term speed reductions and what very much appealed was that rather than displaying driver speeds, the VATCS uniquely provided a targeted reminder of the speed limit In force combined with a slow down request and dynamic flashing beacons.
17 solar powered VATCS are to be installed across the City this summer including two signs which will feature in the Mayland Heights Community Traffic Study. See plan attached.
Spencer Beier, Unipart Dorman’s west coast representative commented "It has been a pleasure working with the Calgary City traffic planning team on this unique new approach, and this pilot project, together with the recent introduction of the technology in North Vancouver, BC. Calgary has really raised the bar in display based traffic calming and put the new technology on the map in Western Canada."
SynchroGUIDE receives accolades in Oklahoma as NEW MUTCD to adopt Sequential Warning Light Benefits
Regular visitors to our site will be aware that SynchroGUIDE was awarded the 2007 “Top Rollout” award category for innovation from the ‘Better Roads’ publication at the end of 2007 after being first launched in north America earlier that same year.
Unipart Dorman and Dicke Safety Products are further pleased to report tangible safety benefits are now arriving from the field. Such an example being Oklahoma DOT who have been field testing the technology at a number of problematic workzone sites on I35 at which arrow boards were already deployed. SynchroGUIDE once installed provided the solution. The added safety factor that the technology imparted received a number of accolades from the driving public and an excellent testimonial from the DOT resident engineer Cary ‘Red’ Raley. Read OKDOT testimonial below.
There were 835 fatalities and over 41,000 injuries in work zones during 2007 and it has been shown that over 85% of the fatalities in work zones are drivers or passengers in cars entering the zone. Motorists and workers are being increasingly exposed to work zones as the federal stimulus expenditure on road infrastructure investment kicks in during 2009 and the introduction of Synchroguide’s proven improved lane discipline couldn’t be better timed.
In addition Night work is increasingly being used to manage work zone delay and reduce exposure, and with the SynchroGUIDE safety factor enhanced in night time applications, the technology is truly starting to make its mark as a potential life saver.
