Dynamic evaluation index of Urban Mass Transit

As the Urban Mass Transit operating evaluation criteria are inconsistent, many design basis are non-uniform correspondingly. The domestic and abroad dynamical evaluation index of Urban Mass Transit are summed up in this paper, such as derailment coefficient, reduction rate of wheel load, acceleration of carbody, sperling´s ride index, the wheel/rail vertical force, wheel/axis horizontal force and wheel/rail horizontal force etc, which supply reference for China´s Urban Mass Transit construction and development.
