R.C. ‘n’ P.W. by Julia First5/18/2023 ![]() We observe that semi-actuated control is better for the average delay in comparison to fixed control when the main road has the same or a higher load than the crossing roads. ![]() Our approach proves to be both accurate and fast compared to traffic microsimulation, allowing us to optimise the traffic-light settings and offsets.īy analysing our model for two intersections in tandem, we show the important differences between semi-actuated and fixed controls. In our model, we explicitly consider slow-departing vehicles in the beginning of a green period and the offsets between intersections. In this paper, we propose a queueing model for traffic-light networks under fixed and semi-actuated control. With increasing congestion in urban areas, it is important to characterise existing traffic control policies in terms of their performance and their optimal settings. ![]() Our claims regarding complexity and accuracy are confirmed in practice by a set of comprehensive benchmarks. Our algorithm is implemented in a companion library, written in standard C and released as an open-source project. ![]() In this paper we study the dynamics of damped Traub’s methods Tδ\documentclass$, or for sparse polynomials, our algorithm performs much better than this upper bound, without any modification or parameterization.The article contains a detailed analysis of the complexity and a full error analysis, which guarantees that the algorithm performs as well as H\''orner's scheme, only faster. ![]()
