Question

On a highway, if the velocity of the moving vehicle on a lane is 40 kmph, stopping distance is 20 m and average length of vehicle is 5 m, then the basic capacity of lane is

• A. 2000 vehicles per hour
• B. 1600 vehicles per hour
• C. 2400 vehicles per hour
• D. 1200 vehicles per hour

Answer 1

The correct option is B 1600 vehicles per hour

$Basiccapacity,C=\frac{1000V}{S}$
V = 40 kmph
S = stopping distance + $l$
= 20 + 5 = 25 m
$\therefore C=\frac{1000\times 40}{25}=1600\text{vehicles per hour}$
