Abstract

Method for controlling street lighting over a plurality of interconnected road segments (2a-2q), in which a road class is dynamically assigned to each road segment (2a-2q) on the basis of, at least, stored road type data associated to each road segment and traffic parameters determined for each road segment (2a-2q) for a current time period. At least a corresponding maximum lighting level (P max ) is associated to each road class. In this method, signals comprising speed and direction of travel data of road users (20,21,22,21a-21c), and an identification of the road user (20,21,22,21a-21c) are propagated through series of adjacent road segments (2a-2q) starting from each road user's road segment (2a-2q), and a new lighting level (P new ) equal to said maximum lighting level (P max ) is set at each road segment (2a-2q) whose distance (d) to the road user's road segment (2a-2q) is not greater than a first distance (r 1 ). A control device (6) for implementing the above method is also dislcosed.

Description

technical field [0001] The present disclosure relates to methods, systems and devices for controlling street lighting, as well as computer programs for executing such control methods and street lighting systems suitable for being controlled by such control methods. In the context of this disclosure, "street lighting" shall be understood as the lighting of any street, road, path, highway, railway, tunnel, navigable waterway, canal, or any other transportation corridor. Background technique [0002] Today, the energy demand of a system has become a key criterion for evaluating its performance. In practice, higher energy consumption results in greater cost and increased complexity. Often power generation can also damage the environment, for example through greenhouse gas emissions, radioactive waste or other damaging factors. For these reasons, there is a strong demand for reduction of energy consumption in street lighting systems. [0003] Over the past decade, new lighting...
