Abstract A three-dimensional theory of motion discomfort is developed by defining scalar indices measuring discomfort due to acceleration and jerk. These indices are functions of effective acceleration and jerk vectors and their orientation to the preferred configuration of a subject. The optimal bank angle of a guideway is defined and shown to minimize acceleration discomfort. Isotropic approximations to the discomfort indices are proposed. Expressions for the indices are obtained in terms of the vehicle motion and guideway geometry. Deatiled analyses of motion along optimally banked circular helical and three-dimensional spiral curves are presented. Motion with zero fore-aft thrust on a curve in a vertical plane is also detailed. The approach assumes a smooth guideway and so vibrational inputs are not included. The analysis should be followed up by an experimental program before it is taken too seriously in design.
