Traffic Simulation

TRANSIMS uses a synthetic population, activity plans, and feedback to simulate route choices made by urban travelers in response to congestion. In this simulation sequence, red denotes congestion and green, free flow. Snapshots are for traffic in Portland, Oregon, at 9 A.M. Three iterations (top to bottom) show how traffic spreads and congestion is reduced as simulated drivers choose new routes to avoid delays encountered in previous iterations.
