title: An energy efficient pedestrian aware Smart Street Lighting system
abstract: Conventional street lighting systems in areas with a low frequency of passersby are online most of the night without purpose. The consequence is that a large amount of power is wasted meaninglessly. With the broad availability of flexible lighting technology like light emitting diode lamps and everywhere available wireless internet connection, fast reacting, reliably operating, and power conserving street lighting systems become reality. The purpose of this work is to describe the Smart Street Lighting (SSL) system, a first approach to accomplish the demand for flexible public lighting systems. This work presents the SSL system, a framework developed for a dynamic switching of street lamps based on pedestrians' locations and desired safety (or "fear" zones. In the developed system prototype, each pedestrian is localized via his/her smartphone, periodically sending location and configuration information to the SSL server. For street lamp control, each and every lampp.

title: Smart street lighting management
abstract: In this work, we propose a new street lighting energy management system in order to reduce energy consumption. The key idea we want to accomplish is that of "energy on demand" meaning that energy, in this case light, is provided only when needed. In order to achieve this goal, it is critical to have a reliable demand model, which in the case of street lighting turns out to be a traffic flow rate forecasting model. In order to achieve this goal, several methods on the 1 h prediction have been compared and the one providing the best results is based on artificial neural networks. Moreover, several control strategies have been tested and the one which gave the best energy savings is the adaptive one we carried out. Experimentation has been carried out on real data and the study shows that with the proposed approach, it is possible to save up to 50 of energy compared to no regulation systems.

title: Smart Street Lighting: Campus Pilot
abstract: To benefit city and university goals, the team created this proposal for a smart street lighting pilot on campus. Benchmarking analysis allowed for the selection of the most appropriate smart street lighting components for the university: computer vision, dimming, and air quality monitoring. Cost and funding research, as well as a survey of the OSU community, provided an idea of the project's feasibility. Analysis of crime and traffic patterns on campus allowed for the selection of the location that would best fit the pilot. AEDE 4567 Spring Semester April 18, 2017 Table 1.

title: Smart Street lighting System
abstract: This paper is about a smart lighting system that can control the street light efficiently by using sensors to dim and brighten whenever it is required. This system is based on the concept of IoT(Internet of Things) It helps to reduce the number of accidents that takes place on the roads and also saves a lot of power and electricity. It increases safety and provides more efficiency. It also provides a safe environment for the pedestrians during the night time by lighting up the place.

title: Solid State Light Sources Getting Smart
abstract: More than a century after the introduction of incandescent lighting and half a century after the introduction of fluorescent lighting, solid state light sources are revolutionizing an increasing number of applications. Whereas the efficiency of conventional incandescent and fluorescent lights is limited by fundamental factors that cannot be overcome, the efficiency of solid state sources is limited only by human creativity and imagination. The high efficiency of solid state sources already provides energy savings and environmental benefits in a number of applications. However, solid state sources also offer controllability of their spectral power distribution, spatial distribution, color temperature, temporal modulation, and polarization properties. Such "smart" light sources can adjust to specific environments and requirements, a property that could result in tremendous benefits in lighting, automobiles, transportation, communication, imaging, agriculture, and medicine.

title: Estimating Energy Savings in Smart Street Lighting by Using an Adaptive Control System
abstract: The driving force behind the smart city initiative is to offer better, more specialized services which can improve the quality of life of the citizens while promoting sustainability. To achieve both of these apparently competing goals, services must be increasingly autonomous and continuously adaptive to changes in their environment and the information coming from other services. In this paper we focus on smart lighting, a relevant application domain for which we propose an intelligent street light control system based on adaptive behavior rules. We evaluate our approach by using a simulator which combines wireless sensor networks and belief desire intention (BDI) agents to enable a precise simulation of both the city infrastructure and the adaptive behavior that it implements. The results reveal energy savings of close to 35% when the lighting system implements an adaptive behavior as opposed to a rigid, predefined behavior.

title: Zigbee based Smart Street Lighting System
abstract: Street light, a raised source of light that is commonly used along walkways and streets when the surrounding turns dark. Currently, various street lighting control systems technology have been developed to control and maintain these systems more economically. However, most of these systems developed have contributed some drawbacks. They have been considered to be outdated due to lack of communication capabilities, not allowing a system feedback. Hence, Zigbee communication technology is deployed so as to ensure a higher efficiency and overcome current drawbacks. The system will be able to detect fault and apprise the control room about it. Keywords outdated communication, feedback, Zigbee

title: PLC based Smart Street Lighting Control
abstract: Conventional street lighting systems in most of the areas are Online at regular intervals of time irrespective of the seasonal variations. The street lights are simply switched on at afternoon and turned off in the morning. The consequence is that a large amount of Power is wasted meaninglessly. As energy consumption is an issue of increasing interest, possible energy savings in public street lighting systems are recently discussed from different viewpoints. The purpose of this work is to describe the Smart Street Lighting system, an approach to accomplish the demand for flexible public lighting systems using a Programmable Logic controller (PLC) The main difference from other computers is that PLCs are armoured for severe conditions such as dust, moisture, heat, cold etc. and have the facility for extensive input/output (I/O) arrangements. In the proposed paper, street lights are controlled using millennium 3 PLC taking the seasonal variations into consideration.
