Re: Solved
Exactly.
These things aren't switching small loads either. Could they make it smaller? I don't know. I'm not a traffic engineer. But I tend to think a microprocessor would blow up if it had to deal with the wattage that an intersection runs on. |

During our power outage last Fall (freak October snowstorm in buffalo), signal department had small gasoline powered generators (1500 Watt) running traffic signals at major intersections throughout the city. These are like ten three-bulb signals at each intersection of six lane highways. I doubt if much power is involved. The man-power involved was unbelievable though. Three police cars and a three man signal crew which went up and down the highways keeping the signals gasoline generators running. And this for 24 hours and the three days until power restored. |
