Abstract
At an urban intersection, traffic performance is highly influenced not only by signal timing schemes but also by lane assignments. However, dynamic adjustment of lane configurations remains understudied due to the prevalent use of predetermined lane arrangements. To address this research gap, we propose the TransLane framework, which collaboratively optimizes time and space resources within an intersection by implementing dynamic lanes. We model each intersection as an agent and apply a hierarchical recommendation approach to these agents. Additionally, the framework addresses the challenge of training an agent in the absence of sufficient data by using transfer learning techniques. Specifically, a new intersection agent can be trained from pre-trained agents via model and sample transfer mechanisms, which facilitate the reuse of traffic control knowledge from similar intersections. The efficacy and superiority of TransLane are demonstrated through simulation studies that show it outperforms models that optimize space or time resources independently using widely adopted traffic control optimization methods.
