A city uses a computer simulation to test how a new traffic light pattern would affect congestion before changing any real lights. What is the main benefit?

  1. The simulation is guaranteed to match reality exactly
  2. Ideas can be tested quickly and cheaply without disrupting real traffic
  3. The simulation removes the need for any data
  4. Simulations cannot contain bias
