![]() 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. ![]()
