CRITERIA FOR SUPER-ELEVATION OF CURVES WITH CONSTANT RADIUS

CRITERIA TE STELLEN AAN DE VERKANTING VAN EEN BOCHT MET CONSTANTE STRAAL

A theory is presented for the degree of superelevation required for two different kinds of vehicles: a relatively tall and softly sprung truck and a relatively low and rigid passenger car. The banking angle has been calculated as a function of speed of travel, road curvature and a possible cross wind force. Three different criteria are employed: the limit of overturning, of sliding and of comfort. The truck appears to be most sensitive to overturning. Sliding depends on the coefficient of friction existing between tyre and road surface. The limit for comfort is derived from two assumed values of maximally accepted lateral acceleration. Again, the truck with its strong tendency to roll sets the limit. /TRRL/
