Abstract
There exist several control approaches for traffic signal control such as
fixed-time, vehicle-actuated, or look-ahead traffic-adaptive control. We argue
that in order to flexibly deal with varying demand levels movement-based
control (which is already common in vehicle-actuated intersection control) is
required instead of stage-based control (which is still employed in the
state-of-the-art in look-ahead traffic-adaptive control). The movement-based
approach is more flexible than the stage-based approach as it allows green for
signals in different stages to start sooner if the demand for all conflicting
movements in the current stage has cleared. Therefore, we propose a new
movement-based method for look-ahead traffic-adaptive
control. The method uses dynamic programming and branch-and-bound algorithms to
determine the optimal traffic signal settings. We illustrate via a simulation
example that the new approach can significantly outperform vehicle-actuated and
stage-based look-ahead traffic-adaptive control.
