The dynamic traffic control problem and the dynamic traffic assignment problem are integrated as a noncooperative game between a traffic authority and highway users. The objective of the combined control-assignment problem is to find a mutually consistent dynamic system-optimal signal setting and dynamic user-optimal traffic flow. The combined control-assignment problem is first formulated as a one-level Cournot game: the traffic authority and the users choose their strategies simultaneously. The combined control-assignment problem is subsequently formulated as a bi-level Stackelberg game. The traffic authority is the leader; it determines the signal settings in anticipation of the users’ reactions. The users are followers who choose their routes after the signal settings have been determined. Finally, the system-optimal control-assignment problem is formulated as a Monopoly game. The sole player—the traffic authority—determines both signal settings and traffic flows to achieve a dynamic system-optimal solution. A numerical example is provided to illustrate the equilibria of the games.

This paper presents a dynamic version of Braesss paradox in transportation networks. This time-varying paradox considers queue spillback in dynamic traffic assignment. Five independent considerations in relation to the traffic-flow component are discussed. The queue spillback in respect to the spatial queue assumptions has been investigated in detail. Finally, some solutions based on the view of planners, decision-makers and managers are demonstrated to resolve the potential paradoxes, such as lane partitioning, road reconfiguration, congestion charging, time-varying tolls, ramp metering and dynamic traffic control and management etc.

The cooperation of urban traffic control system and urban traffic flow guidance system may perform an important role in alleviating traffic congestion. To achieve this objective, a dynamic traffic coordination control model of traffic congestion based on synergetics is proposed in this paper. After that approach, a simulation scheme based on VISSIM 4.2 is carried to evaluate the reliability of the model. The results proved that the whole system could benefit a lot.
