Question

What will be the theoretical maximum capacity (to nearest 10 units) for a single lane of highway given that the speed of the traffic stream is 40 kmph?

• A. 2860 veh/h
• B. 2510 veh/h
• C. 3000 veh/h
• D. 2010 veh/h

Answer 1

The correct option is A 2860 veh/h

Theoretical maximum capacity,

$C=\frac{1000V}{S}veh/hr$
V= 40 kmph
S = Minimum clear distance between two vehicles
S = 0.2 V + 6
= 0.2$\times$ 40 + 6 = 14m
$C=\frac{1000\times 40}{14}=2857.14Veh/hr$
