This paper describes a new approach to control traffic signals at isolated intersections by capturing vehicles’ delay times and utilize them to adjust the green times. Similar to a traditional vehicle actuated control a queue clearing policy is applied: Within the bounds of a minimum and a maximum green time, a running green phase is terminated as soon as the accumulated delay on an approach is dissolved. The strength of this new approach is that it can be used for new data-sources like probe vehicles, video cameras, or vehicle infrastructure integration (VII). To assess the quality of the new method, a simulation study is performed which demonstrates that it outperforms the traditional approaches, with the additional benefit of robustness against a particular kind of measurement error.

The DVD lists the title of this paper as: Delay-Time Actuated Traffic Signal Control for Isolated Intersections.
