Most of them do not work, this 8 year old NYT article claims that 120 out of 3250 signals in NY work a decrease from their census in 2004 and mentions how a different agency found 1 working button across various cities. The only ones that kind of work in my experience are in New Jersey, where if you do not press the button, the intersection will never clear you to walk. The signals and everything work the same, just you will never get walk at the intersection (even when you normally would have) without pressing the button.
If people are frequently crossing between crosswalks, there probably aren’t enough crosswalks. If they’re pressing the buttons but crossing before the light changes, even if the buttons do cause the lights to change eventually they’re probably set up incorrectly and make wait times too long.
It took me 18 months of back and forth with my city to get them to fix a particular light. The beg buttons technically worked, but the light is where a major street intersects with a residential street, and all the beg buttons would do initially was make the pedestrian lights turn green the next time the lights changed. Problem was, if it didn’t detect a car there it would never trigger a change. What finally got it fixed was me sending the city council an 8 minute video of me waiting for the light to change before a car came along.
Do they ever? You don’t get to control traffic as a random person on the street—for anything that’s not a super low traffic street, mostly in residential areas. Maybe it works like the weight sensors at stop lights, where it doesn’t exactly change the cycle, it just lets the system know not to keep the most heavily trafficked road going?
I’d imagine. I dunno. I just always assumed they did nothing.
There are pedestrian crossings that are not at an intersection but a straight road, where pressing the button does stop the cars for you to cross. There is no cycle, the cars have green until someone wants to cross
Yeah, that’s what I meant. I’ve seen those, there are a bunch in my parents neighborhood. I meant more at like a four way intersection. The button don’t do shit when traffic lights are timed.
And later at night in slower areas with less traffic, the more “main” road of the two intersecting will stay green until a car comes and stops at the red light on the less traveled road. In that instance, the crosswalk button might do something.
In the Netherlands the intersections sense bicycles coming and try to give you a green light before you even slow down to stop. This is because a typical intersection can fit many more bikes through faster than cars. Bikes are prioritised for this reason. Cars have low priority because they’re slow, unwieldy, and inefficient. Besides, if your trip were important, you would have ridden your bike like a normal person.
In my city there is a T intersection where the top part of the T is a busy road with a traffic light and I once saw some kids pressing the button as a “joke” when they are not even crossing. Usually its always green but if it turns red it causes a huge lineup of cars, especially during rush hour.
