Epidemiology ; Mortality ; Risk ; Road accident ; Road traffic ; South Africa ; Spatial differentiation
In view of the large and increasing road traffic fatality burden in South Africa, this study describes the risk of fatal road traffic injuries according to population and rural-urban characteristics in the country between 2002 and 2006. There were
Animal habitat isolation by roads and agricultural fields
Road construction and agricultural activities contribute to habitat isolation. Field studies suggest that roads represent barriers and cut off the gene flow by dividing animal populations into fractions on either side of the road. Several mobility
diagrams show significant isolation effects of roads on population of forest-dwelling mice (Apodemus flavicollis) and carabid beetles.
Forest roads and geomorphic process interactions, Cascade Range, Oregon
Erosion control ; Flood ; Forest ; Geotechnics ; Impact ; Mass movement ; Mountain ; Oregon ; Rainstorm ; Road ; Sediment budget ; Soil erosion ; United States of America ; Watershed
A major flood in February 1996 triggered more than 100 geomorphic features affecting forest roads in a 181 km2 study area in the western Cascade Range, Oregon. Eight types of features, including mass movements and fluvial features, were mapped
, measured and analysed using geographic information systems and sediment budgets for the road network. The net effect of roads was an increase in basin-wide sediment production. Overall this study indicated that the nature of geomorphic processes influenced
by roads is strongly conditioned by road location and construction practices, basin geology and storm characteristics.
Sediment production from granitic cutslopes on forest roads in Idaho, USA
Hydrologic and geomorphic effects of forest roads. Special issue
Erosion control ; Forest ; Geotechnics ; Granite ; Idaho ; Mountain ; Road ; Slope gradient ; Soil erosion ; United States of America ; Water erosion ; Weathering
A series of 75 non-bordered plots was used to measure surface erosion on granitic road cuts on forest roads in the mountains of Idaho. Erosion data were collected for 4 years following road construction. Both mass and surface erosion processes were
observed on road cuts. Regression analysis showed slope gradient, slope aspect, ground cover density and snow-free period rainfall erosivity had statistically significant effects on erosion. Slope gradient was the most influential site factor affecting
The Andaman Trunk Road - Life Line or Death Spell ?

A road that stretches north-south across the main Andaman Islands in the Indian Ocean threatens the life of the Jarawa tribe to whom the islands have been home and refuge for thousands if not tens of thousands of years. The road has changed the life
of the Jarawas irreversibly. Vulnerable to diseases brought in by the road traffic and settlers, their physical existence is in jeopardy. The Andaman Trunk Road was built as a contribution to development and civilization. The question is, who are the stakeholders
in the ATR, what are the costs, what are the benefits and how does the road compare to the alternative concept of waterways. - (IfL)
Concept ; Definition ; Mobility ; Road ; Russia ; Settlement ; Siberia ; Social geography ; Traveller's tale ; Way of life
This article proposes that the term road provides a concept of theoretical value for anthropological discussions of mobility. Based on ethnographic research in two neighbouring settlements in Siberia, I discuss the range of stories indigenous
residents offered during our discussions of roads. Their definitions of roads contrast with those used more globally. A hodological approach to the concept of road demonstrates connections among ideas of kinship, movement, nomadism, metaphor and knowledge
. Accounts from the social lives of travellers enlarge the possibilities of understanding the relationship between roads and narrative.

in a 170m wide swath along road corridors. The lateral extent of the environmental impact of roads in the study area is greater than is commonly perceived. The approach described herein demonstrates a simple method to assess the spatial association of mass
Az alfoldi megyék kozuthalozatanak topologiai vizsgalata. (Topological investigations of the road-network in the counties of the Great Hungarian Plain)
Topological analysis enabled the AA. to characterize and compare the road-network of the counties in the Great Hungarian Plain. It will be followed by a non-topological investigation where they have to calculate the actual geographical location
of roads, settlements, distances and the intensity of transport linkages. (CK).
A change in the policy climate? Current European perspectives on road pricing
Attitude ; Behaviour ; Congestion ; Europe ; European Union ; Price fixing ; Road ; Tariff rate ; Transport cost ; User Behaviour
The paper traces changes in attitudes towards road pricing in the European Community, both on the part of the politicians and the general public and its representative organisations, across the range of member states and their geographical
neighbours. it identifies the development of a European congestion consciousness. Important role played by municipalities. Road-pricing policy is examined.
Runoff generation and sediment production on unpaved roads, footpaths and agricultural land surfaces in northern Thailand
Cultivated surface ; Model ; Rainfall simulation ; Rill wash ; Road ; Sediment transport ; Soil erosion ; Thailand ; Tropical zone
Rainfall simulation was used to examine runoff generation and sediment transport on roads, paths and 3 types of agricultural fields in Pang Khum Experimental Watershed (PKEW), in mountainous northern Thailand. Because interception of subsurface flow
by the road prism is rare in PKEW, work focused on Horton overland flow (HOF)

This study reports the nature of sediment delivery pathways and road-to-stream linkage in a forested catchment in southeastern Australia, and evaluates the causal factors associated with this linkage. Results are discussed within the context of road
There are special sections of the public roads, the so-called ’scenic roads’, which are considered to be interesting and specific regarding the aspects of landscape and view. The aim of the study is to draw attention of the values of landscape
. In the study the authors undertook to plan a ’scenic road’ which connects two castles being apart within distance of sight of each other in the area. In addition to the presentation of values of landscape aligning along the scenic road, a visibility map
