Vehicle Movement based Innovative Smart Highway Lighting System

Road networks are a vital part of modern travel; there are currently 21 million kilometers of road networks throughout the world. Using a regression model with an adjusted R2 of 0.90, it is estimated that by 2050, an extra 3.0 - 4.7 million km of road will be paved. This brings up the well-explored domain of automating lighting systems. There have been numerous works trying to optimize road lighting systems, but most of them are statically programed or face problems with up-scaling. The goal of this paper is to design and implement advanced development in embedded systems for energy conservation in street lights. This work uses a decentralized approach which enables us to control each node /street light individually as well as a group through the use of NRF 24L01 Transceiver module), the Sensing Unit (Ultrasonic sensor HC-SR04 ), Microcontroller Unit (Arduino Nano), and Lighting System. The design flow takes care of scenarios where if one or more of the nodes/ sensors fail it will not affect the entire row of streetlights. This work aims at creating a dynamically programed automatic street lighting system with the main focus on scalability. Our goal is to create a synchronized array of nodes that may accept new nodes without requiring any changes to the existing nodes. This allows the ability to increase the size of the automation-network swiftly. Finally, the system was conceived and implemented successfully as a prototype for Smart highway lighting system.
