How quiet is the operation of a PRT vehicle?
Movement of the vehicles will be much quieter than automobiles. They are propelled and braked through linear electric motors, which are driven by variable-frequency drives. Such drives may produce a humming sound, which is minimized by careful design and by sound insulation. Since there is no braking or traction through the wheels, the tires are smooth and they run on smooth surfaces, so the tire noise will be substantially less than produced by an automobile. There are no other noise-producing elements. Return to Top of Page.
