The Urban population is growing so fast in India that planning officials are racing to keep up with urban development .Use of geographic information like satellite imagery helps urban planners manage the ever-changing urban environment accurately and efficiently. Roads are one of the most important features to be extracted from Satellite imagery for urban planning. Manual extraction of roads is...
Low level of driver’s situation awareness (SA) and high level of cognitive load are considered as reasons of vehicle accidents. Cognitive load is higher when driving abroad because of unfamiliarity with differences in international traffic rules or vehicle configurations. This paper aims to objectively assess the driver’s SA when performing lane changing tasks under unfamiliar driving condition...
Our study focused on the putative effects of roads on small-mammal communities in a high desert region of southern Utah. Specifically, we tested whether or not roads create adjacent zones characterized by lower smallmammal densities, abundance, and diversity. We sampled abundance of small mammals at increasing distances from Interstate 15 during two summers. We recorded 11 genera and 13 species...
*Correspondence to: Charles H. Luce, Rocky Mountain Research Station, Boise Aquatic Sciences Laboratory, 316 E. Myrtle, Boise, ID 83702, USA. E-mail: [email protected] Forest roads are an important environmental issue. While many scientists interested in hydrology recognize climate-altering processes as an important global issue, there are problems that are similar in scope and magnitude because ...
Roads are becoming deterioration in everywhere. In some places, traffic marks painted on roads are damaged thus needed to be updated. Municipalities must manage road condition and traffic marks (road painting). It is the municipalities task to manage those roads using, for example, special inspection cars and human eyes. However, the management cost is high if a city contains many roads. This p...
Archaeological remains of roads are often neglected in settlement surveys. Because they are found between sites, roads are an important component of the landscape. In this paper, we apply the concept of landscape capital as defined by Harold Brookfield to preColumbian roads in the Amazon region of northeastern Bolivia. Previous studies have documented the importance of raised earthen causeways ...
Since roads play an important role in many application areas, up-to-date road databases are critical. Automated road extraction using many different types of remote sensing data has been explored. Recently, lidar data has proven advantageous for road extraction and researchers have extracted roads from lidar data alone as well as fused with passive imagery. This paper considers techniques to ex...
Previous studies suggest that eastern chipmunks (Tamias striatus) avoid roads, but it is unclear whether vehicle traffic plays a role in this avoidance. The purpose of this study was to determine whether road avoidance in chipmunks increases with traffic. We tracked the movements of 68 chipmunks released near roads with widely varying volumes of traffic. Our results suggest that chipmunks respo...
An approach for the automatic extraction of roads from digital aerial imagery is proposed. It is optimized for rural areas and makes use of versions of an aerial image with different resolutions. Roads are modeled as a network of intersections and links between these intersections, and are found by a grouping process. The context of roads is hierarchically structured into a global and a local l...
The misclassification of roads and parking lots is one of the major difficulties in automating road network extraction from high resolution remotely-sensed imagery, especially in urban areas. This paper proposes a new integrated approach to road identification on high resolution multi-spectral imagery. The input images are first segmented using a traditional k-means clustering on normalized dig...
