Because the vehicles weigh a small fraction of conventional rail transit vehicles, the electric current required is correspondingly less and any magnetic field in the cabin will be proportional to the current. While there are at present no generally accepted safety standards that limit human exposure to magnetic fields, care has been exercised in the design of the vehicles to minimize the exposure of passengers to magnetic fields. The motors are designed to constrain the magnetic fields to their immediate vicinity and are located remotely from the passenger compartment, which also desirably lowers the center of gravity of the vehicle. Residents living or working near a PRT guideway will not be exposed to any significant increase in magnetic fields since the power to the vehicles is provided from 600-volt DC power rails inside a shielded guideway. Harmful effects of transmission lines have been reported only when the lines carry several hundred thousand volts.
