- mcguire 7y agoHow long would it take you to install a traffic light camera system? Would you do that for $100?
- imglorp 7y agoIt's probably easier to install than the typical sensor loop under the asphalt. The camera and cpu could be on the same circuit board as one of the LED lens units, which are already sealed units heated against snow. It would need an additional comm line down to the controller from each light head, which might just be a cable pull through conduit.
- lm28469 7y agoBesides being weather proof it would also need to be theft proof. It would also probably have to pass some sort of certification(s) as it would control traffic lights which could be dangerous in case of malfunctions, regular tests, &c. I'm all for optimising things but sometimes it's just not worth the hassle. A well timed orange light is good enough.
