The local city and county keep the traffic lights running all night. That is, they do not change to blinking red late at night unlike many other cities.
I’ve always been under the impression that blinking was more efficient during the low traffic volumes at night. No one is stopped for a couple minutes at an empty intersection, and perhaps it is less costly in terms of electric usage. True, the red lights burn out more quickly, but the yellow and green less quickly.
Can anyone confirm or refute my impression? Assuming I am correct, I’d like to have some arguments to bring to the local governments to petition the change. Especially the electricity part, seeing as how the west coast is having energy problems. If the savings are significant, that by itself might be all the argument I need.
