Liverpool early to mid 1970s...
Dad had a friend who worked in a bunker in a cellar somewhere off the Dock Road or there abouts or near the town hall. I remember a row of CRT monitors set into grey desks with joystick controllers in front. As you moved the joystick, the monochrome CCTV cameras dotted around Liverpool city centre moved. Pressing a rocker switch on the end of the joystick zoomed in or out. Traffic flows were monitored visually as well as using pneumatic sensors set into the roads near traffic lights. A computer matched the traffic lights to the average speed of traffic through the city centre. The average speed was shown on a large display. It struck me at the time (as an abnoxious teenager) that the drivers of the cars throught they were in control with the illusion of agency, but really the computer program was in charge of the *average* movement through the centre, so that any relative advantage you gained in one section of road would result in a longer wait at a subsequent set of lights. 
I supose as the cost (both capital and energy to run) of computing devices continues to drop  we will see more of 'management' of cities.
