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.

Wps=V/9.5*√R.
Wps=50/9.5*√80=0.589
So answer =B.
Wps=50/9.5*√80=0.589
So answer =B.

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

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