Evaluation of a Traffic-Aware Smart Highway Lighting System

Abstract

Highway lighting consumes considerable amounts of energy, yet smart lighting techniques provide significant potential for reducing this consumption. This paper introduces a preliminary algorithm, simulation studies and a small-scale hardware prototype for a smart highway lighting management system based on road occupancy. Wireless Sensor Network (WSN) detects the presence of vehicles along the road, and controls lighting accordingly. The system is evaluated through two different simulation studies: using a realistic model for vehicles traffic based on cellular automata (Nagel-Shreckenberg model), and using state-of-the-art Simulation of Urban Mobility (SUMO) traffic simulator. Simulations provide estimation for expected energy saving rates at different cases and scenarios. According to simulation results, the proposed system can save up to 57.4% of power consumption compared to conventional lighting systems.

A new street lighting control algorithm based on forecasted traffic data for electricity consumption reduction

“…Kova `cs et al 24 developed a central controller system ensuring the adaptation of the lighting system by controlling the daily switch on-off times and the dimming levels of the lamps. An interesting algorithm and a small-scale hardware prototype were also developed in a previous work 25 for an intelligent highway lighting management system based on traffic conditions. A wireless sensor network (WSN) detects the presence of vehicles along the street and adjusts the lighting intensity.…”

Internet of Things data analytics for parking availability prediction and guidance

“…This trend is part of the current Internetof-Things (IoT) evolution that is powering the reach to contextual information of a wide range of future smart-city sub-systems, such as energy, waste and traffic management. Smart-poles are part of this evolution whereby junctions are able to identify traffic patterns across outgoing edges [2,3,4,5,6]. Using traffic sensors, a pole can detect the movements of individual vehicles, leading to a range of analytical applications to improve traffic-induced issues including parking-related ones.…”
