Question

The flow rate on an arterial is 1,800 veh/h, evenly distributed over two lanes. If the average speed in these lanes is 40 mi/h, what is the density in veh/h/ln?

Answer 1

Using

q = k*v,

where q = traffic flow rate, k = density, v = space mean speed.

so, 1800 = k x 40

so, k = 1800/40 = 45 veh/mie on two lanes,

so k = 45/2 = 22.5veh/h/in
