Identification of major sources of airborne pollutants and their contribution to pollutant loadings are critical in developing effective pollution control and mitigation strategies. In this study, a comprehensive dataset of non-methane volatile organic compounds (NMVOCs) collected from August 2001 to December 2002 at a polluted rural/coastal site in the Pearl River Delta (PRD) is analyzed to as...

-Pollution in air is generated by the developments, which typically occur as the country gradually shifts towards industrialization, due to city growth, increasing traffic, rapid economic development, and higher levels of energy consumption. Indian cities are among the most polluted cities in the world. The main source of air pollution in Indian metropolitan cities is petrol and diesel driven v...

OBJECTIVE The main objective of this paper is to assess the impact of various vehicular traffic densities on lead (Pb) accumulations in some environmental components in Katsina, a semi-arid urban area of Nigeria. METHODS This was achieved by collecting and analyzing samples of surface soils, fruits, kernels, leaves, and barks of Balanites aegyptica from locations of different vehicular traffi...

present transplant study was carried out across lucknow, the capital of utter pardesh using two medicinally important plants viz., ?catharanthus roseus l.? and ?ocimum sanctum l.? to assess whether certain ecophysiological responses (change in total flavonoids and total phenolics) in these two plants may serve as the biomarkers of auto exhaust pollution. samples were taken from five different s...

This paper presents a vehicle’s CO2 emission reduction scheme by an ETC-assisted real-time traffic light control scheme in vehicular networks. Using Electronic Toll Collection (ETC) devices, real-time road conditions can be obtained by wireless communication between the ETC devices and the traffic lights. A decision tree classification algorithm is used to assign the changing policy for the tra...

Over the past decades, the fast growth in travel has increased traffic congestion, which in turn has increased vehicular emissions significantly. It is difficult to accurately estimate and quantify emissions with current practice because of its reliance on transportation planning models that are based on steady state hourly averages and thus are incapable of capturing the effects of traffic var...

Line source emission modelling is an important tool in control and management of vehicular exhaust emissions (VEEs) in urban environment. The US Environmental Protection Agency and many other research institutes have developed a number of line source models (LSMs) to describe temporal and spatial distribution of VEEs on roadways. Most of these models are either deterministic and/or statistical ...

Vehicular communications, referring to information exchange among vehicles, pedestrians, and infrastructures, have become very popular and been widely studied recently due to its great potential to support intelligent transportation and various safety applications. Via vehicular communications, manually driving vehicles and autonomous vehicles can collect useful information to improve traffic s...
