TL;DR: This work used the road network dataset from the open street map with a specific buffer to extract the road area as a constraint region and the grayscale brightness of JL1-3B images was obtained by integrating all the three bands to locate the street light by using a local maximum algorithm.
Abstract: To realize energy conservation and environmental protection, solar street lights have been widely used in urban areas in China. To reasonably and effectively utilize solar street lights, the original street lights must be located, and the solar street light potential must be assessed. The Jilin1-03B (JL1-3B) satellite provides next-generation nighttime light data with a high spatial resolution and in three spectral bands. Consequently, the street lights can be extracted from the nighttime light data. We used the road network dataset from the open street map with a specific buffer to extract the road area as a constraint region. Next, the grayscale brightness of JL1-3B images was obtained by integrating all the three bands to locate the street light by using a local maximum algorithm. Then, the values of the original three bands were utilized to classify the types of street lights as high-pressure sodium (HPS) lamps or light-emitting diode lamps. Finally, we simulated the replacement of all the HPS lamps with solar street lights and assessed the corresponding solar energy potential by using the digital surface model data and hourly cloud cover data through the SHORTWAVE-C model. The accuracy of location of the street lights was approximately 90%. Replacing an HPS lamp by one solar street light for 20 years can save 1.85 × 104 kWh of electrical energy, 7.41 t of standard coal, 5.03 t of C emissions, 18.47 t of CO2 emissions, 0.55 t of SO2 emissions, and 0.28 t of NOX emissions.

TL;DR: In this paper, the authors designed an integratif control and monitoring of the public street lighting system based on the Internet of Things (IoT) system to solve the problems.
Abstract: At present, public street lighting system control at most of the urban is only by conventional control, a control switch set in each of the streets lamps which are ineffective in power consumption and a excess of human resources, and unwieldly to operate the street light opening and closing time. Several methods tend to overcome these problems, such as a time-control method that is, from time to time opening and closing control, and time-optical-control method that is, from time to time with light intensity control. However, these methods also face other problems because of un-integrated systems, such as monitoring and maintenance of lamps condition and power consumption. This paper is trying to design an integratif control and monitoring of the system based on the Internet of Things (IoT) system to solve the problems. A number of sensors, such as PZEM-004T and Light Dependent Resistor (LDR), Arduino Mega 2560 microprocessor system, relays, and a software Graphical User Interface (GUI), are utilized in this research. An Ethernet system with ThingSpeak application is used for telecommunication between the public street lighting system with a monitoring system. Several experiments had been performed that proved the proposed system able to maintain the public street lighting system more satisfaction, low maintenance system, and accurate.

TL;DR: The proposed approach gives a method to conserve power by using the PIR sensors to sense the incoming traffic and hence turning ON a cluster of lights surrounding the traffic.
Abstract: The adaptive street light has the ability to adapt to the motion of cycles, cars and pedestrians. It uses motion as well as light sensors to detect the traffic and light around. It dims when there is no movement on the road, and is brightened when there is any activity. Smart street lights are very dissimilar from the old methods of lighting. It is an automated system that will be able to automate the streets. The main objective of these lights is to decrease the utilization of power, while no activity is detected on the street. It will be switched ON while there are pedestrians and cars on the street or else they will get dimmed to 20% of the brightness. The proposed approach gives a method to conserve power by using the PIR sensors to sense the incoming traffic and hence turning ON a cluster of lights surrounding the traffic. As the traffic is passing by, the street lights left behind will dim on its own. Hence, a lot of power can be conserved. Also, during the day time when there is no need of light the LDR sensor will sense the light and the light will remain switched OFF. This smart street light system comes under the domain of smart city.

TL;DR: In this paper, the authors provide a comprehensive examination of the effect of street lights on crime and find that outdoor nighttime crimes change very little on street segments affected by street light outages, but crime appears to spillover to nearby street segments during these outages.
Abstract: For more than one hundred years, street lighting has been one of the most enduring capital investments to maintain public safety. In this study we provide a comprehensive examination of the effect of street lights on crime, by estimating the effect of nearly 300,000 street light outages in Chicago neighborhoods on crime. We find that outdoor nighttime crimes change very little on street segments affected by street light outages, but that crime appears to spillover to nearby street segments during these outages. These findings suggest that crime may follow patterns of human activity and that the impact of localized street light outages can reverberate throughout a community.

TL;DR: The result shows that the smart street light system is expected to reduce energy consumption up to 45.48% on weekdays and 32.22% on weekends from the presentStreet light system which uses timer system.
Abstract: The electricity generation cost is escalating every year while the electric energy is indispensable and increasing in demand. The resources for energy generation is also depleting due to the increasing demand of power. Thus, a system that can reduce the energy wastage and the massive expenses is essential. Street light system is one of the systems that can reduce energy consumption. The massive energy consumption from the current street light system is not efficient enough to reduce the wasted energy. By implementing an IOT-based smart street light system, the power consumption of the street light will be optimized. This system will also provide the ability to monitor input voltage for Arduino MEGA 2560 microcontroller and control the street light through IOT. The concept of this smart system is to introduce an intelligent system which can decide to switch on or off the street light according to the movement detection by using an infrared sensor module. The data will be sent to Arduino Mega 2560, which is a microcontroller that will decide to turn on or off the street light. The Wi-Fi module ESP-01 is implemented to enable the microcontroller to connect to Blynk software for monitoring and controlling purpose. The result shows that the smart street light system is expected to reduce energy consumption up to 45.48% on weekdays and 32.22% on weekends from the present street light system which uses timer system. The IOT-based Smart Street Light system also shows the condition of the street light system based on the Blynk interfaces for maintenance purpose.
