today, vehicular ad-hoc network between automobiles has been accepted by the public, and many people are interested in exchanging information with other vehicles as well as with roadside equipment while driving. when a number of vehicles want to access to the data stored in rsu ,the priority of servicing comes into face .in this case, some  methods, such as d*s, d*s/n,  have been presented so f...

This paper presents a neural network based novel automated system that can analyze vehicle mounted video data for improving road safety. There are video data collection systems currently available although no tools exist which could be used to automatically analyze vehicle mounted video data and estimate future crash sites. The main aim of the research presented in this paper is to develop a te...

The paper provides data on the fl oristic composition of vegetation in anthropogenic habitats suitable for Erigeron × huelsenii, a spontaneous hybrid between the alien E. canadensis and native E. acris s. str. The study is based on 21 phytosociological relevés (vegetation plots) of 5×5 m size made in 2013–2014 in the Polish part of the Lithuanian Lakeland (north-eastern Poland) using the Braun-...

Vegetation as an essential positive sustainable element of urban spaces has recently gathered increased attention from landscape architects and urban planners. Vegetation growing in urban settings can bring environmental benefits that enhance the health and well-being of citizens through, for example, improved air quality, increased thermal insulation for buildings, reduction of the urban heat-...

Roadside point counts are generally used for large surveys to increase the number of samples. We examined differences in species detected from roadside versus off-road (200-m and 400-m) point counts in the Shenandoah National Park. We also compared the list of species detected in the first 3 minutes to those detected in 10 minutes for potential species biases. Results from 81 paired roadside an...

Human-mediated dispersal is known as an important driver of long-distance dispersal for plants but underlying mechanisms have rarely been assessed. Road corridors function as routes of secondary dispersal for many plant species but the extent to which vehicles support this process remains unclear. In this paper we quantify dispersal distances and seed deposition of plant species moved over the ...

Combustion-derived black carbon has received attention as a form of refractory organic carbon that may be preferentially preserved in soils and sediments. However, little is understood about the environmental roles of black carbon in urban soils. This investigation represented the preliminary study to characterize black carbon (BC) concentrations and enrichment ratios in Xuzhou urban roadside t...

Now a days heavy metal contamination along the roadside is matter of concern especially in industrial areas developing countries. The non-degradable nature metals makes them injurious to all living beings. Soil, dust, and plants are main media for entry these into our food chain. Thereby, survey was conducted assess nickel (Ni), copper (Cu) manganese (Mn) levels soil maize crop growing roadside...
