Societies face the challenge of keeping people active as they age. Walkable neighborhoods have been associated with physical activity, but more rigorous analytical approaches are needed. Researchers used longitudinal data from adult residents of Brisbane, Australia (40–65 years of age at baseline) to estimate effects of changes in neighborhood characteristics over a 6-y period on the likelihood of walking for transport.

Cool materials with higher solar reflectance compared with conventional materials of the same color are widely used to maintain cooler urban fabrics when exposed to solar irradiation and to mitigate the Urban Heat Island (UHI). Photo-catalytic coatings are also useful to reduce air pollutants. Many studies related to these topics have been carried out during the past few years, although the lighting implication of reflective coatings have hardly been explored.

India’s road length increased by 1.31 lakh kilometres within a span of one year between March 2015 and March 2016, according to the latest report released by the road transport and highways ministry. This translates to adding 360 km daily to the country’s road network in comparison to 170 km and 190 km per day in 2013-14 and 2014-15 respectively. India’s road network increased from 54.72 lakh kms to 56.03 lakh kms on the back of higher pace of construction of rural roads which pushed up the total length by almost half.

Urban road infrastructure is crucial in determining air pollution. Yet, little is known about the roles played by road width vs. road length. This paper attempts to fill this gap by estimating the effects of road infrastructure on 10-micron particulate matter (PM10) using city-level data from the People’s Republic of China (PRC).

In urban street canyons, external noise environment is a critical restriction to the opening of building windows for natural ventilation. The high external noise intensities are often used to substantiate the utilization of air conditioning systems in residential and commercial buildings. Therefore, a systematic method of examining the noise levels in urban street canyons is essential if the potential for natural ventilation is to be estimated.
