The basic objective of this study has been to address the issue of how adequate point-mass representations are in predicting friction requirements for actual vehicles operating along superelevated curves. An existing comprehensive computer model used for predicting transient or nonsteady maneuvering situations was also employed to analyze friction demand while maneuvering along superelevated curves. Highway tests were then performed for two passenger cars and a five-axle tractor-semitrailer to collect representative test data and assist in validing the predictions of the computer models. Finally, a sensitivity analysis was performed to illustrate the relative importance and interactions of various vehicle parameters and highway geometrics in influencing side friction requirements.
