The lane configuration with lane volumes in vehicles per hour of a four-arm signalized intersection is shown in the figure. There are only two phases: the first phase is for the East-West and the West-East through movements, and the second phase is for the North-South and South-North through movements. There are no turning movements. Assume that the saturation flow is 1800 vehicles per hour per lane for each lane and the total lost time for the first and the second phases together is 9 seconds.

For a traffic stream, V is the space mean speed, k is the density, q is the flow. V_f is the free flow speed, and k_f is the jam density. Assume that the speed decreases linearly with density.

Which of the following relations is/are correct?

$$q = {k_j}k - \left( {{{{k_j}} \over {{V_f}}}} \right){k^2}$$

$$q = {k_j}V - \left( {{{{k_j}} \over {{V_f}}}} \right){V^2}$$

$$q = {V_f}V - \left( {{{{V_f}} \over {{k_j}}}} \right){V^2}$$

$$q = {V_f}k - \left( {{{{V_f}} \over {{k_j}}}} \right){k^2}$$
