ou are going to design a circular curve in a rural road segment where the design vehicle is a passenger car of operation speed is 90 km/h. The width of the lanes of the proposed road is 3.5m. Based on a survey at the proposed site, it has been found that a multi-storied building is located towards the inside of the curve at 10 m from the centerline of the highway.

You are going to design a circular curve in a rural road segment where the design vehicle
is a passenger car of operation speed is 90 km/h. The width of the lanes of the proposed
road is 3.5m. Based on a
building is located towards the inside of the curve at 10 m from the centerline of the
highway. Considering perception reaction time as 2.5 s design the horizontal curve (Rdesign,
edesign and fdesign) for that road segment. Record the radius and respective safe sight distance
in the tabular format while selecting design radius (word table), plot them in Excel graph
and find the Rdesignfor the safe sight distance. If there is no superelevation, what would be
the alternative arrangement?
