In an attempt to increase efficiency, Georgia Tech has trialled a new bus scheduling system where the vehicles move in relation to each other rather than at set times. This is designed to prevent "bus bunching," where several buses race to the same stop at once to catch up with unavoidable hurdles in the inflexible schedule. The system uses Android tablets with GPS that report the bus's position to a central server, which in turn uses algorithms to calculate and relay information back to the driver on how best to proceed.
The results of the system's first test were positive — average headways between buses were both shorter and more predictable, and the system also managed to automatically re-equalize the headways once a bus had been...
