One of the most important pollution in world is air pollution. factors that cause this vehicles. Heavy metals have a great role component caused by vehicles and they negative effects on plant human health. In study, it was aimed to determine effect distance from highway leaf morphology anatomy economically Red Globe grape variety. Leaf samples were collected four different distances (road side,...
This study evaluates individual preferences for five different cycling environments by trading off a better facility with a higher travel time against a less attractive facility at a lower travel time. The tradeoff of travel time to amenities of a particular facility informs our understanding of the value attached to different attributes such as bike-lanes, off-road trails, or side-street parki...
In almost all urban contexts and in many extra-urban conurbations, where road traffic is the main noise pollution source, the use of barriers is not allowed. In these cases, low-noise road surfaces are the most used mitigation action together with traffic flow reduction. Selecting the optimal surface is only the first problem that the public administration has to face. In the second place, it h...
the aim of this research paper is the introduction of a novel mathematical approach to improvethe accuracy of the results of air pollution dispersion models based on the calibration of input backgroundconcentrations. using the dunkirk area of the city of nottingham in the uk as a case study, an air pollutionmodel in adms-roads was created for developing the mathematical approach. the iterative ...
Although road traffic has supported high economic growth after the war, it has also caused serious social problems about traffic accidents, traffic congestion, and environmental pollution. Information and communication technology (ICT), such as computers, mobile communications, and digital information processing, has made rapid progress, in the second half of the 20th century. Intelligent Trans...
in this study, the effects of road salting on the quality of forest soils near the road were monitored in the Krkonoše Mountains (Czech republic). Physical, chemical properties and microbial parameters of soils were determined and the toxic potentials of soil water extracts were evaluated using the bacterial tests (Microtox and Pseudomonas putida growth inhibition test). increased concentration...
This paper presents a novel method MGARS to automatic road area segmentation based on motion and gray feature for the purpose of urban traffic surveillance. The proposed method can locate road region by region growing algorithm with the fusion feature of motion information and grayscale of background image, which is independent to road marker information. An adaptive background subtraction appr...
Many governments subsidize regional rail service as an alternative to road traffic. This paper assesses whether increases in service frequency reduce road traffic externalities. We exploit differences in service frequency growth by procurement mode following a railway reform in Germany to address endogeneity of service growth. Increases in service frequency reduce the number of severe road traf...
With the fast increasing popularity of mobile smart devices, mobile crowd sensing has become a new paradigm of applications that enables the ubiquitous mobile devices with enhanced sensing capabilities, such as smartphones and wearable devices, to collect and to share local information towards a common goal. Most of the smart devices are equipped with a rich set of cheap and powerful sensors, f...
Industrialization and urbanization taking place at faster rate in Coimbatore city. Hence the discharge rate of industry effluents and wastes are increasing at alarming rate. These effluents and wastes are being discharged randomly on soil, river, lake and road side without any treatment. They pollute productive soil, natural water system as well as ground water. Assessment of heavy metal conten...
