Road traffic injuries are an ongoing global health burden and cause more than 1.2 million deaths per year. In Europe, the annual socioeconomic impact accounts for €130 billion. In 2011, the United Nations set a special focus on road safety and injury prevention by the proclamation of the “Decade of Action for Road Safety.” This initiative focuses mainly on developing countries. In Germany, many ...
Previous research has shown that forest roads are an important feature in many landscapes and have significant effects on wildfire ignition and cessation. However, forest road effects on burn severity have not been studied at the landscape level. Therefore, the overarching goal of our study is to identify the influences of road edge effects on the spatial patterns of burn severity. We analyzed ...
The aim of current research is to assess of landslide susceptibility in the Khalkhal Township, southern Ardabil using an ensemble and new method namely Bayesian and logistic regression (BT-LR) models. At first, landslide inventory map was prepared and then effective factors on landslide occurrence were identified. These factors are slope degree, plan curvature, slope aspect, elevation, landuse,...
Major investments in infrastructure rehabilitation have been undertaken by govemments, development banks and donors in developing countries in recent decades. In Sub-Saharan Africa road deterioration is perceived to be one ofthe main causes for the limited supply response after price liberalization in agricultural markets. Studies of the quantitative effects on marketing margins are rare. This ...
One of our first activities in natural resources management and development programs is to acquire knowledge on Landslide Susceptible areas. The aim of this research is landslide hazard zonation in some part of Haraz watershed between Vana village and Emam zadeh Ali, using fuzzy membership functions and fuzzy operators. At first landslide points were recognized using arial photography and field...
Investigating the factors affecting the occurrence of mass movements, help to identify sensitive areas and providing solutions and ways to control and proper management, partly to prevent the occurrence of mass movements. This research tried to recognize the factor affecting the occurrence of mass movements in the Forest Park Abidar watershed. In this research, information layers including lith...
Identification of factors affecting on existing of landslide as well as its zonation in the given watershed is one of the basic tools for landslide control and selection of approach and effective solution as well. In this study landslide hazard mapping provided using previous landslide distribution and multivariate regression model in GIS environment in Aghmashhad. With reviewing previous resou...
In this study, Neuro-Fuzzy model was used to prepare the map of Vaz watershed landslide susceptibility in GIS environment. Location of landslides occurred in the study area was determined through interpretation of aerial photographs and the field monitoring. In the nextstep, factors affecting landslide occurrence such as altitude, lithology, slope, aspect, distance to drainage, distance to ro...

BACKGROUND There is widespread public concern that exposure to road vehicle traffic pollution causes asthma, but epidemiological studies in developed countries have not generally confirmed a strong effect and may have underestimated the risk as a result of relatively high and widespread exposure to traffic in everyday life. AIMS To investigate the effect of living close to a traffic bearing r...
