Similarly, K = Kj (1 − u uf ) Where: u = speed at any time uf = free flow speed K = traffic density at any time Kf = jam density 4.2. Flow-Density Model. Assumes that the relationship between flow and density is parabolic. From q = Kus , q = K(uf) (1 − K Kj ) q = uf (K − K2 Kj ) Note that this model is parabolic in the variable K. Where: q = traffic flow at any time uf = free flow speed K = traffic density at any time Kf = jam density 4.3. Flow-Speed Model. Assumes that the relationship between flow and speed is parabolic.
