The first of many new traffic lights for the City of Hamilton have been unveiled.After nearly 30 years in service, Hamilton's old lights are being decommissioned, one set at a time.City engineer Patrick Cooper and general superintendent David Monkman this afternoon demonstrated the first “puffin” (Pedestrian User-Friendly Intelligent Crossing Lights), now up and running by Fagans Alley, on Front Street.Mr Cooper said: “We've just done a set by the number six terminal. Others this year will be the Court and Front Street intersection. New lights will go in at number one dock, and I believe at Court and Dundonald Streets too.”It will cost the City roughly $100,000 per junction, he added, with “18 to 20 intersections” to switch as the whole city gets new lights over the next four years. While the lights are going in, many junctions will get new contours.“We'll be looking at the geometry of the road at the same time,” Mr Cooper said.Pedestrians may be surprised not to see the familiar green and red icons positioned on either side of the road. They are now on the screen above the push button, so that pedestrians are looking at traffic while they watch the screen.The familiar sequence of beeps is also gone. The visually impaired will be told when to cross by a spinning button under the screen.Useful web link: www.cityhall.bm
