Calgary had a population of 80,000 in 1931 , and traffic was becoming troublesome in downtown district.
Traffic control to that point was effected by police officers, either through hand signals or a manually operated signal with arms that read “stop” and “go” On Oct. 29 , a bevy of top-coated dignitaries gathered to throw the switch that activated the city’s brand-new traffic signal system.
The system is monitored 24 hours a day from the city’s traffic management centre.
Technicians sit at computers that constantly receive data from sensors and from the traffic signals themselves.
The data could be co-ordinated with images on large screens fed by cameras mounted at intersections and traffic hot spots throughout the city.
