Title: ASPECTS OF SPIRAL TRANSITION CURVE DESIGN
Accession Number: 00172409
Record Type: Component
Availability: Find a library where document is available Abstract: Some aspects of the design of spiral transition curves on highways are discussed, and a model for the relation between the design speed and the rate of change of centrifugal acceleration is presented. The model is based on the principle that higher speeds require higher comfort. An identity between the spiral length given by the model and the length of the superelevation runoff is assumed. A modified criterion for the maximum relative slope of the centerline and the edges of a two-lane pavement is proposed. The values for the rate of change of centrifugal acceleration and the maximum relative slope suggested are shown to be reasonable. /Author/
