Shippers are users of the transportation services. Shippers choose a sequence of carriers, based on the carriers’ pricing and routing decisions.

NettetIn an alternative recently introduced model, the travel time for a vehicle entering a link at time t is taken as a function of an estimate of the flow in the immediate neighbourhood of the vehicle, averaged over the time the vehicle is traversing the link. NettetThis function presumes that coefficient α (often set to 0.15) is the ratio of travel time per unit distance at practical capacity to that at free flow, and parameter β (often set to 4) determines how fast the estimated average link speed, u as a function of x, decreases from free-flow to congested conditions.
