A traffic flow has density 61 veh/km when the speed is 59 veh/hr. If a flow has a jam density of 122 veh/km, what is the maximum flow in veh/hr (in whole number)? Use Greenshield Model.

Sagot :

Lanuel

Since this traffic flow has a jam density of 122 veh/km, the maximum flow is equal to 3,599 veh/hr.

Given the following data:

  • Density = 61 veh/km.
  • Speed = 59 km/hr.
  • Jam density = 122 veh/km.

How to calculate the maximum flow.

According to Greenshield Model, maximum flow is given by this formula:

[tex]q_{max}=\frac{V_f \times K_i}{4}[/tex]

Where:

  • [tex]V_f[/tex] is the free flow speed.
  • [tex]K_i[/tex] is the Jam density.

In order to calculate the free flow speed, we would use this formula:

[tex]V_f =2 V\\\\V_f =2\times 59\\\\V_f=118\;km/hr[/tex]

Substituting the parameters into the model, we have:

[tex]q_{max}=\frac{118 \times 122}{4}\\\\q_{max}=\frac{14396}{4}[/tex]

Max flow = 3,599 veh/hr.
