Optimal traffic-light settings are generally hard to obtain, certainly foractuated access control of an intersection. Typically, computationallyexpensive (microscopic) simulations or complicated optimization schemes arerequired to find those optimal settings. Based on recent developments regardingthe Fixed-Cycle Traffic-Light (FCTL) queue, we propose a new allocation schemefor actuated access control at isolated intersections. Our scheme allows forvery easy computations and an intuitive explanation, which are both based onthe Central Limit Theorem, a key tool in probability theory. The desirableproperties observed for the FCTL queue can also be achieved in case of actuatedaccess control of an intersection. We show this by means of simulation of theunderlying queueing model, because the actuated control defies an exactanalysis so far. We also observe the same type of results employing themicroscopic traffic simulator SUMO. The intuition and insights obtained mightalso open up new possibilities for obtaining optimal actuated access controlfor a network of intersections.
