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...

Concentrations, composition and sources apportionment of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in the edible bivalves (oysters, mussels and clams) and sipunculida samples collected from coastal areas of Beibu Gulf, China. The results showed that the total PAH concentrations ranged from 36.4 to 403.3 ng/g dry weight. Compared with other bays and coastal areas, current cont...

The main reason for using alternative fuels in compression ignition engine is that the consumption and demand of petroleum products are increasing every year due to urbanization, increase in vehicular density and power requirement is going up and to reduce emission produced by today’s diesel engine, which in turns require a clean burning fuel that perform well under the variety of operating con...
