Street lighting control, energy consumption optimization

Abstract

Using a graph formalism to model outdoor lighting infrastructure has proven to be an efficient method for both design and control. It has been tested not only on laboratory scale, but also in a cityscale deployment. The paper proposes further energy usage optimization if the streetlights are dynamically controlled. It is to alter the design process taking into account influence of the control schemas. As a result substantial energy consumption savings can be achieved. The introduced optimization is also modeled with graphs and graph transformations.
