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.

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.

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.

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.
