🚦 Traffic Junction (Simulation) · Mission 4 of 5

🚗 Busy Road

Rush hour: east–west is packed, north–south is quiet. A plain timer gets only about 70 cars through in a minute. Use the car counts to get at least 90 through, without anyone waiting more than 20 seconds.

Your mission

1. Both red (the start): ns = "green".
2. Keep every green for at least 5 seconds (sim.seconds >= 5).
3. After that, switch to the other road if it has more cars waiting (sim.waitingNS, sim.waitingEW), or if this green has lasted 15 seconds, so the quiet road isn't forgotten.
