Request what? The surveillance system? No. That said many on HN where strong proponents of it when it was announced because it was marketed as providing data the city government could use to make improvements.
Cameras can be at every intersection all the time and can adapt in real-time to emerging traffic patterns (ie a ballgame ending and a stadium of people hitting the road at once) as well as traffic changes over time from environmental changes
A camera is cheaper and a camera can measure speed as well as slowdowns and stoppages that a tube simply can't do. A tube was the old way but if you're going to make a new device a camera makes more sense.
