You press the button and wait. The red light stays on. You press again and wait longer. Does this sound familiar?
Crosswalk buttons, also called pedestrian push buttons, are found in nearly every city across the globe. But what do they really do? Do they speed up the process? Or are they just there to reassure us?
Let’s take a closer look at what’s really happening at the intersection.
How They’re Supposed to Work
In theory, crosswalk buttons send a signal to the traffic light controller, asking for a “WALK” signal.
Here’s how it works:
- The button sends a digital signal to the intersection's control box.
- Your request gets added to the traffic light's timing cycle.
- The next time it’s safe, you’ll get the walk signal.
Simple, right?
When They Don’t Work at All
Here’s the twist: in many cities, particularly large ones like New York, London, and Tel Aviv, those buttons do nothing.
Why is that?
Many intersections operate on pre-programmed traffic cycles that ignore pedestrian requests during peak hours. In fact, during COVID-19, some cities turned off the buttons completely and never reconnected them.
A study in NYC found that only 9% of crosswalk buttons affected the signal.
The “Placebo Button” Effect
Sometimes called “placebo buttons,” these are installed and often left working simply to give people a sense of control.
You feel better pressing it, but the system has already made its decision.
Ironically, pressing the button repeatedly doesn’t help either. Once your request is received, any additional presses are ignored.
Not Just Buttons: Accessibility Features
Today’s crosswalks often include features for people with visual impairments:
- Audible tones: Beeps or chirps to indicate when to cross.
- Vibration indicators: A small rumble felt when it’s safe.
- Braille instructions: Usually found on newer installations.
These features are crucial for accessibility and work even when the button is not functioning properly.
Do They Work in Smaller Cities?
Yes, in many smaller towns and suburban areas, crosswalk buttons are still connected to the control system.
Pressing the button can:
- Trigger a walk cycle more quickly.
- Extend the crossing time if the system detects a pedestrian.
So next time you're in a small town, go ahead and push that button.
Pro Tip: One Press Is Enough
If the system is working correctly, you only need to press it once. Pressing it repeatedly won’t speed things up; it will just test your patience.
Final Thought
Crosswalk buttons are a mix of engineering, psychology, and public safety. Sometimes they work, and sometimes they don’t. But now you know the real story.
So next time you're waiting at the corner, ask yourself: Am I changing the signal or just keeping my fingers busy?
