A Taxonomy of Adaptive Traffic Signal Control

2023-08-03 · Andalib Shams, A. M. Tahsin Emtenan, Christopher M. Day

Research on adaptive traffic signal control (ATSC) extends back to at least the 1960s, and many ATSC methods have been proposed over the years. This paper provides a review of this research and proposes a taxonomy for organizing it, accompanied by a consistent vocabulary for discussing the control concepts. We begin from the well-established concept of control generations. Next, we classify the ATSC methods according to their topographic structure (local-only, system/hierarchical), time resolution of decision-making (continuous versus planning-horizon), type of decision (rule-based or optimization), objective function, cyclic/acyclic nature,and additional subcategories relevant to certain "families" of methods. These various elements of system control are organized into a taxonomy of ATSC to help future researchers understand the wide diversity of algorithmic approaches to the signal control problem that have been proposed to date, and which can be updated or expanded to incorporate future research.
