It’s one of those little frustrations; having to stop for a red light after you just lucked out at another intersection.
The city says its trying to do better at synchronizing traffic lights so that doesn’t happen.
Troy Macleod, Director of Roads for the City of Calgary, says the problem its encountering now is aging infrastructure in the core.
He says copper wire is being changed out for technologically advanced fibre-optic cable. Macleod says the traffic control centre re-syncs every controller just after midnight, but if one signal loses communication it can’t be controlled.
“You’ll see more improvements in the downtown as we expand our fibre,” he says.
Macleod compares it to “synchronizing watches”:
“Imagine that you each had a watch and they were all perfectly synchronized; when you reach a traffic signal you’d flow nicely right through them. But, once that time shifts you lose that coordination no matter how good your timing plan is.”
He says the city is working at better coordination and has added 180 signals to the central traffic control system.
