 According to the U.S. Department of Transportation, AGT systems as a group have higher injury rates than any other form of rail-based transit (subway, metro, light rail, or commuter rail) though still much better than ordinary buses or cars.More recent research by the British company ULTra PRT reported that AGT systems have a better safety than more conventional, non-automated modes.As with many current transit systems, personal passenger safety concerns are likely to be addressed through CCTV monitoring, and communication with a central command center from which engineering or other assistance may be dispatched.
