Abstract: The objective of this paper is to develop the 85th percentile operating speed models at mid-curve that can be integrated based on shoulder width, degree of curve, length and radius of simple horizontal curves for the horizontal curve on Kerala two-lane rural highways conditions. The speed data measurement is based on Spot Speed Data at specified points and location manually.. The geometric parameters such as radius of curve, shoulder width, degree of curve and length of curve are used to recognize the effect of operating speed models at the mid-curve. If this 85th percentile operating speed prediction model using multiple linear regression analysis is implemented and enhanced into current guideline and standard in Kerala, it could play an important role in designing or redesigning of the horizontal alignment for two-lane rural highway in Kerala.
