Roads have a multitude of negative effects on wildlife, including bat casualties. Most species rely life history traits characterised by high adult survival (associated with greater longevity) and low reproduction rates (hence slow population growth rates). Therefore, road kills are expected to negatively affect local abundance dynamics. Bat overpasses among the proposed improvements intended i...

Pavement structures cover vast areas of urban cities and non-urban roads play a key role in daily commuting functionality economic development; therefore, they must be conserved against any distress. The rutting problem, being major distress to the pavement structure, solved dealt with order preserve its value. One way solving this dilemma is by using geo-grids within structure. A geo-grid synt...

Direct and indirect ecological impacts of roads and their expansion are well documented: habitat degradation, ecosystem fragmentation, changes in natural drainage systems and water quality. Important landscape scale impacts concern roads about direct and indirect effects on deforestation and land use land cover change, that lead to habitat loss and fragmentation, edge effect, resources exploita...

Accidents due to cross the lane (lane departure crash) of achieving 19% of all accidents. These accidents mostly caused because the driver is not concentrating or dozing. A device that can help the driver so that the vehicle does not exit lanes known as Active Lane Keeping Assist (ALKA). ALKA is a subsystem of Advanced Driver Assistance System (ADAS) and is now used in several brands of cars na...

Anthropogenic infrastructure such as roads and non-native species are major causes of species endangerment. Understanding animal behavioral responses to roads and traffic provides insight into causes and mechanisms of effects of linear development on wildlife and aids effective mitigation and conservation. We investigated effects of roads and traffic on space use and movements of two forest-dwe...

Not very successfully at all, according to a recent study which suggests that the high density of roads in many areas may be creating isolated populations of these key invertebrates, reducing genetic heterogeneity and increasing the possibility of local extinctions. Irene Keller and Carlo Largiader at the University of Berne, Switzerland, have carried out a study on the large, flightless ground...

The algorithm assumes that object motion is restricted to a horizontal plane ( for example motion of cars on roads or humans walking). Dense stereo image sequences and the Visualised Locus method [1] [2] (in which each image sequence is first sampled to produce a 2D spatiotemporal cross-section image) are used to ensure temporal correspondence without search. Edge segments in the left and right...
