Abstract: Passenger comfort at high maglev vehicle speeds (110 to 134 meters per second) has significant impact on the proposed use of the existing highway and railroad rights-of-way for hosting maglev guideway alignments. This paper examines comfort parameters as a constraint on maglev guideway route alignment. Effects of speed, maximum bank angle, and unbalanced lateral loads are examined. Additionally, the effects of roll rate limits and jerk are examined with respect to necessary spiral transition lengths. The difficulty in maintaining high speeds and ride quality within recommended comfort limits without leaving existing rights-of-way may require a reassessment of ride-quality standards as applied to maglev transportation and a commitment to new rights-of-way or significant excursions from existing rights-of-way.
