• Bus bunching
• Transit operations
• Headway control
• Adaptive control
• Self-organization

The primary challenge for an urban bus system is to maintain constant headways between successive buses. Most bus systems try to achieve this by adherence to a schedule; but this is undermined by the tendency of headways to collapse, so that buses travel in bunches. To counter this, we propose a new method of coordinating buses. Our method abandons the idea of a schedule and even any a priori target headway. Under our scheme headways are dynamically self-equalizing and the natural headway of the system tends to emerge spontaneously. Headways also become self-correcting in that after disturbances they reequalize without intervention by management or even awareness of the drivers.
We report on a successful implementation to control a bus route in Atlanta.
