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...

There is an increasing scientific interest in studying vehicular traffic pollution road tunnels. This due both to the evaluating effect that different polluting gases can have on driving style of motorists and also hypothesis tunnels could be considered as closed systems which traffic–pollution correlation easier study because it more easily separated from other effects. In this work, a system ...

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...

Vehicular networks have attracted increasing attention from both the academy and industry. Applications of vehicular networks require efficient data communications between vehicles, whose performance is concerned with delivery ratio, delivery delay, and routing cost. The most previous work of routing in vehicular networks assumes oversimplified node mobility when evaluating the performance of v...

The entrances of tunnels are generally considered to be accident-prone locations, and accidents related this area mainly include rear-end sideswipe crashes, which also associated with lane-changing behaviours. Despite the extensive literature on safety lane-changing, little attention has been given behaviours in front tunnel entrance. To end, study investigates contributing factors potential ri...

Telematics communication technologies and vehicular networks have been identified as key technologies for increasing road safety and transport efficiency. Telematics communication technologies and vehicular networks aim to ensure traffic safety for drivers, provide comfort for passengers and reduce transportation time and fuel consumption. The development of vehicular communication and networki...

Mobility management is one of the most challenging research issues for vehicular networks to support a variety of intelligent transportation system (ITS) applications. The traditional mobility management schemes for Internet and mobile ad hoc network (MANET) cannot meet the requirements of vehicular networks, and the performance degrades severely due to the unique characteristics of vehicular n...

Vehicle emissions of volatile organic compounds (VOCs) were determined at the Shing Mun Tunnel, Hong Kong in summer and winter of 2003. One hundred and ten VOCs were quantified in this study. The average concentration of the total measured VOCs at the inlet and outlet of the tunnel were 81 250 pptv and 117 850 pptv, respectively. Among the 110 compounds, ethene, ethyne and toluene were the most...
