Automatic control methods applied to freeway network traffic

摘要: The paper presents a general state-space modeling approach for multiorigin multidestination freeway traffic networks including variety of connecting routes each origin-destination pair. problem controlling variable direction signs at bifurcation locations so as to achieve system optimal or user conditions is formulated in control engineering terms. A number well-known strategies are suggested and their effectiveness tested by simulation means real medium-size network. Future research tasks this important application area network outlined.
