Abstract
A personal rapid transit vehicle for movement on a monorail guideway system advantageously limits the vehicle width by requiring the riders to be seated in the vehicle. Furthermore, a suspension system for coupling the vehicle to the guideway provides for a very light, narrow driverless vehicle in which the riders face sideways and are suspended laterally from and seated over the guideway. The suspension system controls lift, slip and roll of the vehicle relative to the guideway and allows a reduction in the guideway cross-sectional area. Moreover, the guideway, rather than the vehicle itself, absorbs all overturning or roll vibration.
