Inappropriate nighttime light reduces living comfort

Environmental Pollution, 2023
Living comfort is an important aspect of human well-being and a critical index of sustainable environments. Many environmental factors are associated with living comfort. Nighttime light (NTL) is remote sensing data that is widely used to reflect development level and economic status, and it also represents the lighting intensity in living environments.

Effects of nighttime lights by LED and fluorescent lighting on human melatonin

Journal of Ambient Intelligence and Humanized Computing, 2016
In this study, we used an LED (light-emitting diodes) light source to develop the the best combination of light wavelengths for nighttime lighting based on the LED advantages of narrow band and controllable spectrum.The action spectrum is based the research of Professor Brainard in the field of non-visual response model, which is used for designing ...

Nighttime Brake-Light Detection by Nakagami Imaging

IEEE Transactions on Intelligent Transportation Systems, 2012
Given the rapid expansion of car ownership worldwide, vehicle safety is an increasingly critical issue in the automobile industry. The reduced cost of cameras and optical devices has made it economically feasible to deploy front-mounted intelligent systems for visual-based event detection for forward collision avoidance and mitigation. While driving at

Frequency-Tuned Nighttime Brake-Light Detection

2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010
Advanced safety vehicle (ASV) is a critical issue in recent years for automobiles, especially when the number of vehicles is growing rapidly world wide. The cost down of general cameras makes it feasible to having an intelligent system of visual-based event detection in front for forward collision avoidance and mitigation.

Uncertainties in VIIRS Nighttime Light Time Series Analysis

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The Nighttime Light (NTL) observed from the Suomi National Polar-orbiting Partnership (SNPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) has shown a strong relationship with socio-economic and environmental variables. The long-term NTL measurements have been used as a primary data source to monitor the temporal dynamics of ...

Population bias in nighttime lights imagery

Remote Sensing Letters, 2019
ABSTRACTBrightness of nighttime lights (NTL) derived from remote sensing imagery has been extensively used to estimate population. However, population bias in NTL images has yet to be investigated. In this study, we explore the associations of race and age demographics with brightness of NTL in the United States (US) for 2015 and 2016.

Nighttime driving: visual, lighting and visibility challenges

Ophthalmic and Physiological Optics, 2019
Abstract Purpose Nighttime driving is dangerous and is one of the most challenging driving situations for most drivers. Fatality rates are higher at night than in the day when adjusted for distances travelled, particularly for crashes involving pedestrians and cyclists.

Lighting Requirements for Nighttime Highway Construction

Journal of Construction Engineering and Management, 2006
This paper presents the development of a practical framework for identifying the lighting requirements for nighttime highway construction activities. The framework is named Construction Visual Requirements, "CONVISUAL," and is designed to consider and quantify the varying lighting needs for different visual and construction tasks.
