Traffic-Adaptive Control of LED-Based Streetlights [Industry Forum] Public lighting in urban environments accounts for about 50% of the electricity con

In this article, a new intelligent street lighting design known as integrated traffic-adaptive control is presented. In general, the strategy is that the luminance intensity of streetlights is either increased or reduced in multiple steps depending on the traffic flow. In a nutshell, higher traffic volume means higher luminance intensity, and vice versa, according to the method specified in the guideline of International Commission on Illumination CIE 115. Data on traffic flow comes from existing roadside infrastructure connected to other management systems, like traffic management, and is interfaced with streetlight management in a common platform. The benefit of such a holistic system approach is that energy consumption of public lighting is reduced without high investments in sensor infrastructure (since existing sensors are used) and without compromising road safety (due to the continuous adjustment of luminance intensity to the traffic volume).
