I rambled earlier about how I can’t stand inefficiently timed traffic lights and how we could reduce idling emissions put out by cars just by having the lights timed better.
Sure, that would help a little, but I think what might help even more is to have them on sensors. It wouldn’t be too hard to retrofit radar sensors onto lights, although sure it might be a little costly. But what’s more costly - radar sensors or those under ground wires they bury?
Here’s the deal on Friday. I woke up at 4:45am, wide awake. After about 20 minutes tossing around, I decided to go to work early and off I go. While on the way, I came to 5 different traffic lights that allow side-street traffic to flow onto more major roads. Every single one turned red right as I got there, with NO ONE coming from the sidestreets. So instead of just sitting there waiting, I decided to go through after stopping.
It’s a known fact that cars pollute more during “cold start” conditions that can last for a varying amount of time depending on the vehicle, your driving habits, speed, etc, so I’ll use the “environmentally unfriendly” concept as an excuse, but it’s also super irritating to have a timed light turn red for NO REASON at all. Especially at 5am when the roads are empty. Here’s a quick solution - make these types of lights so the minor road is blinking red, and the major road is blinking yellow during certain hours of the day. Say like, 11pm to 6am, or whatever traffic surveys show as the low hours of driving.
I know, this is probably really nit-picky (I’ve been called that recently) but it seems like such a waste. And since Americans can’t figure out the “yield to the right” concept, this could be a good 2nd choice. Along with that, make it so the left turns are allowed without a separate signal during these times too. The more you safety-net everyone, the less likely they’ll live up to higher expectations - so give us a chance, the dumb ones will die, but that’s just part of nature.
Now, I’m not like a complete red-light-running fool. The lights that actually had a reason to change because of traffic or pedestrians, I stopped at. There were 2 of those. So on my commute 71% of the red lights I encountered were there to do nothing other than cause irritation, take me longer to get where I was going, and cause my car to pollute more and get worse gas mileage.
