Question

calculate the safe Stopping sight
distance for o design speed for
60 kmph for
two
way
traffic in
Single lane road
Assume f = 0.4 , t = 2.5 sec​

Answer 1

Explanation:

two

way

traffic in

Single lane road

Assume f = 0.4 , t = 2.5 sec

Answer 2

Answer:

V = 50 Kmph

t = 2.5 seconds

f = 0.37

SSD = 0.278 V t + ( V2/ 254 f)

= (0.278 x 50 x 2.5 ) + ( 502/ ( 254 x 0.37))

= 34.75 + 26.60

SSD = 61.35 m. for one way traffic.

SSD for Two Way traffic on single lane road = 2 x SSD for one way traffic

= 2 x 61.35 m

= 122.70 m say 123 m

Explanation:

50 kmph
