System dynamics and feedback control problem formulations for real time dynamic traffic routing

Document Type



This paper formulates the Dynamic Traffic Routing (DTR) problem as a real-time feedback control problem. Three different forms of the formulation are presented: 1. (1) distributed parameter system form derived from the conservation law; 2. (2) space discretized continuous lumped parameter form; 3. (3) space and time discretized lumped parameter form. These formulations can be considered as the starting points for development of feedback control laws for the different control problems stated in this paper. This paper presents the feedback control problems, and does not discuss in detail the methodology of solution techniques which could be used to solve these problems. However, for the sake of completeness a brief treatment of the three forms are included in this paper to show possible ways to design the controllers.
