The game begins in the Stalinian Central Bureau of Traffic Control, where a wrinkly old man pulls you out of your job at the mail room to come save the traffic control system. You are brought to a space command-like control room and put to work setting traffic lights to stop and go. Meanwhile frustrated drivers stuck in the gridlock you create blare their car horns to get your attention, and if their “frustration level” rises too high you fail out of the level. As the road network gets as complicated as four intersections on a square grid, the traffic becomes completely overwhelming and failure is inevitable, but the old man reassures you that they too have failed anyway.
OK, you’ve played the game? If not, don’t go further until you have.
Now that you’ve played the game and failed to control traffic, compare that top-down system with this amazing video a friend sent to me from Cambodia. You’ve gotta see this:
Man, I love this video! I must have watched it a couple dozen times. I keep expecting a crash, in what to me (only being familiar with top-down planned traffic systems) looks like complete chaos. Yet pedestrians, bikes, motorcycles, scooters, rickshaws, and cars all make it to their destinations safely, and probably quicker than in the system in the game above. It must be similar to how capitalism must seem chaotic to people who have always lived in planned economies.
Don’t mistake me as an advocate of a world without traffic signals. I am quite certain that some sort of traffic signaling would likely emerge from a free-market street system. But, my bigger point is that when information is dispersed widely among decision-makers without government monopoly, sustainable solutions emerge from the uncoerced behavior of individual agents over time.
Another article at Infrastructurist discusses the philosophical differences Dutch and American road designs, and gives an example:
A fascinating example is a major–20,000 cars a day!–intersection in the Dutch city of Drachten that used to look a lot a typical American intersection, with lots of bright paint and traffic signals and enormous signs telling you what and what not to do. Traffic planners tore that stuff out and went naked, just putting down a roundabout in the center. The sidewalks even disappeared as distinct structures. Everyone figured it out though. Fatalities at the intersection dropped markedly, as did travel times.
