Intraperiod (Within-Day) Dynamic Models*

The models presented in the previous chapters describe the steady-state behavior of the transport system. Invariance in time of the variables concerned means it can be represented by a single snapshot; a representation that we could therefore call static, the result of an equilibrium assignment, for example, photographs of that particular condition of system behavior in which path (or link) flows and costs are mutually consistent and, as stated above, stationary. This configuration could be observed in the real world only if demand, path choices, and supply system remained constant for a sufficiently long period of time that the system could reach a steady-state condition. Thus, although difficult to observe in reality, as described in Chap. 1, it may be assumed as being representative of average system conditions in the simulation period adopted.
