Offering reliable and effective lighting on roadways, in parks and on residential streets is a critical element of keeping citizens safe. However, city management teams can find themselves scrambling to keep up with light bulbs that need to be changed, broken streetlights and day burners (street lights that stay on during the day). Rethinking street lighting can help reduce energy use, cut costs and address some safety concerns.
Installing sensors on streetlights is a way of using IoT applications in smart cities to help reduce street light management and maintenance costs. The data collected can point to trends and patterns around how often LED luminaire bulbs need to be replaced, for instance, and provides the ability to remotely control dimming to reduce energy usage and cost.
Rather than leave citizens waiting and wondering, the use of IoT in smart cities helps accelerate data collection from the various sensors embedded throughout the city and can help city managers be more transparent about sharing timelines for repair and maintenance through their websites or mobile apps.
Depending on how they're set up, smart streetlights can also serve other purposes, such as providing a wireless broadband connection point or by adding sensors that can analyze traffic speed and pedestrian safety conditions.
