ELI5: How does Singapore control traffic?

Singapore controls traffic by making it expensive and smart to own and drive a car.

Imagine you have lots of toys, but your room is small. If everyone brings all their toys at once, it'll be super crowded and hard to move! That's like Singapore and cars. It's a small island with lots of people, so too many cars would cause big traffic jams.

To avoid this, Singapore uses a few clever tricks:

• Certificate of Entitlement (COE): Think of this like a special ticket you MUST buy before you can even buy a car. These tickets are limited, and they cost A LOT of money. It’s like saying only people who really need a car can afford one.
• Road Pricing: When you drive on busy roads during rush hour, you pay extra! It's like a toll booth, but it's automatic. The money goes to making roads better. This is called Electronic Road Pricing (ERP). Imagine a game where you have to pay a small fee to use the fastest route.
• Public Transportation: Singapore has awesome buses and trains (Mass Rapid Transit - MRT) that go everywhere. They're clean, fast, and cheap! It's like having a super convenient school bus system that takes you anywhere you need to go.
• Strict Rules and Enforcement: There are lots of rules about parking and driving, and people who break them get big fines. It's like having a super strict teacher who makes sure everyone follows the rules.
• Smart Traffic Lights: The traffic lights aren't just on timers. They use cameras to see how many cars are waiting and change the lights to keep traffic flowing smoothly. This is like a smart robot controlling the lights based on what it sees.
