@UKP.
But for hill road widening is provided fully on the inner side, not half.

This is only psychological widening.

Option B is the correct answer.
l^2/2R + V/9.5""R.
0.6^2/2*80 +50/9.5""80 =0.59 answer.
l^2/2R + V/9.5""R.
0.6^2/2*80 +50/9.5""80 =0.59 answer.

Psychological widening : At horizontal curves, drivers have a tendency to maintain a greater clearance between the vehicles than on straight stretches of road. Therefore an extra width of pavement is provided for psychological reasons for greater manoeuvrability of steering at higher speeds and to allow for the extra space requirements for the overhangs of vehicles.

I think the Total widening is L2/2R+V2/9.5*rutR.

X= (18n/R)+(0.1+V/ -^R).
n = No. Of lanes,
R = Radius,
V= speed of vehicle.
n = No. Of lanes,
R = Radius,
V= speed of vehicle.

I think the answer is A because for single lane.
Wpsy =0.
Wpsy =0.
