摘要

The major factor affecting road-user costs (RUC) is the speed at which vehicles operate on roads which in turn determines fuel consumption and other cost components per unit distance travelled. Thus vehicular speed plays a significant role in highway economic evaluation. In the last decade, the Government of India has been involved in road capacity augmentation by building high-speed corridors to link major cities through the implementation of National Highway Development Programme (NHDP) projects such as Golden Quadrilateral, North-South, East-West, Expressway and Port Connectivity corridors. These recent radical changes in road network coupled with enhanced vehicle technology have resulted in huge variations in speed on these highways which has made it essential to evaluate the changing speed characteristics which are important inputs in estimation of RUC. An attempt is made in this article to study the speed characteristics on high-speed multi-lane corridors in plain terrain considering both straight and curved sections spread across the country. From the collected data, free-speed profiles of different vehicle types on high-speed corridors of India are developed and subsequently free-speed equations are developed considering the effect of roadway roughness.
