Abstract

Compared with pre-timed control, actuated control may provide more customized service to individual drivers yet allowing the flexibility to give priority to certain movements typically associated with a surge of demand. In general, actuated control is appropriate for intersections with relatively light traffic on all or part of the approaches, or otherwise the GREEN time in all phases will be frequently stretched to its maximum settings, which essentially renders the traffic signal to a pre-timed control. There are two major types of actuated control: semi-actuated control and fully-actuated control. They have some similarities yet exhibit many differences, which will be elaborated in subsequent sections.
