Question

The theoretical capacity of a traffic lane with one way traffic flow at a stream speed of 60 kmph will be ________ veh/hr/lane. Assume, reaction time = 0.7 seconds and length of vehicle as 6 m.

• A. 3396

Answer 1

The correct option is A 3396
For t = 0.7 sec and $l$ = 6 m
Space headway, $S=S_8+1$

$\Rightarrow S=\frac{5}{18}\times V\times t+6$

$=\frac{5}{18}\times 60\times 0.7+6=17.67m$

$C=\frac{1000V}{S}=\frac{1000\times 60}{17.67}$

$\Rightarrow C=3395.59Veh/hr/lane\simeq 3396$ veh/hr/lane
