• Abstract:
  The strategy retains excellent synchronization on these paths when adapting to residual queues. The synchronization is altered in these cases simply by replacing vehicle trip times with the trip times of backward waves that propagate through queues, as per kinematic wave theory. This has the desirable effect of preventing favored movements from being impeded by queues. (Green phases are initiated for a favored movement only after queues immediately downstream begin moving forward.) The strategy toggles between these forward and backward synchronization modes in zones that are subject to long queues during a rush. A simple algorithm ensures that transitions between these modes occur safely and promptly.
