150÷15 × 7 = 70.

L= eNW
= 1/15*150*7
= 70m.
= 1/15*150*7
= 70m.

Length = eN(W+Widening),
Since widening is not given we consider it 0 here.
e=allowable superelevation.
1/N = 1/150 (given) = rate of change of 'e'.
So N=150.
Length = 0.067*150*(7+0)=70m.

150*x.
where (x) =e(W+We).
We=(Wm+Wp).
Wp- psychological widening =v/9.5√r
Wm- mechanical widening=nl^2/2r.
W=width of road.

We=(Wm+Wp).
Wp- psychological widening =v/9.5√r
Wm- mechanical widening=nl^2/2r.
W=width of road.
