Geometric Design of Highways

By Prof. Rajat Rastogi | IIT Roorkee

Learners enrolled: 2361

ABOUT THE COURSE:

This course on Geometric Design will prepare the students for suitable vacancies in consulting companies which work in the field of Transportation Projects. The student will get complete information on the design factors that need to be considered before planning and designing the road stretches; the elements that constitute a road section based on different expected road users; the design of its horizontal and vertical profile; the estimation of road traffic handling capacity which provides ideas regarding upgradation; the layouts and safety features at an intersection of two or more roads; and finally associated components that are provided as a part of the overall road system. The course will use the IRC and Indo-HCM guidelines during interactions.

INTENDED AUDIENCE: PG and UG

INDUSTRY SUPPORT: All Consulting companies related to transportation projects need candidates with this information
