N2 - This paper demonstrates how the distribution of superelevation and side friction factors over a range of curve radius changes in designing a SMART highway that will be a new design higher-speed 140 km/h highway. The brainwave test and a field study of vehicle speed were carried out in the research to determine proper rates of superelevation and corresponding side friction factors on such high-speed highways. The brainwave test result showed that adjusted side friction factors over a range of curve radius should be applied in SMART highway design. This is due to the driver's changed behaviors on high-speed designed highways, in particular their cautious speed behaviors and sensitive perception of side friction forces. Traditionally, highway engineers applied the Ball-Bank indicator to capture drivers' feelings of discomfort on highway curves, but this research demonstrated that the brainwave test would be a better alternative.
