The reported study employed a virtual reality (VR) system, using a head mounted display (HMD), to investigate road crossing behavior in children and young adults. Younger children (aged 5-9 years) made the greatest number of unsafe road crossings and the oldest participants (aged >19 years) the fewest. Overall performance was better (fewer unsafe road crossings) in uniform speed than uniform di...
this research was aimed to investigate the condition of the existing roads and designing road network based on forest management plan at armardah, baneh. using analytical hierarchy process (ahp) method, the important layers of slope, aspect, forest type and distance to villages and resorts, were weighted and ranked. maps were produced to weighted layers generated in gis to find suitable regions...
Evaluating and comparing the performance of Frequency ratio coefficient models and network analysis in Rock fall zoning (A case study of Zanjan-Taham-Tarom Road) Extended Abstract One of the natural hazards of the collapse of rocks from the foothills of the mountains, causing great financial losses and loss of life. Especially when it comes to the path of communication. The rock fall is a ...
Modelling access to services, using cost path analysis and distance decay models, can be improved if travel time rather than just distance is taken into account. If just straight line distance is used then traffic congestion in urban areas and rough bendy rural roads are not considered in the analysis and the results are subsequently distorted. An accurate road network layer that shows travel s...

Dust emission and sand mobilization are the common natural hazards in desert roads of Iran, which originate from geomorphological facies of road margin. In this study, the geomorphological units of Yazd-Meybod road margin were distinguished, and the samples were taken from these facies as origin area while roads sediment as the transition area of sediments. The samples were analyzed using morph...
Forest roads are the most important elements of forestry projects, the management, supervision, care, and only access way to the forest for mechanized harvesting and using other services of forests. The aim of this study was to compare the current annual increment of basal area in different distances from the road in northern forests of Iran. For this purpose, 50 plots were established in 5 dis...
In this research, logistic regression analysis was used to create a landslide hazard map for Sajaroud basin. At first, an inventory map of 95 landslides was used to preduce a dependent variable, which takes a value of 0 for absence and 1 for presence of landslides. Ten factors affecting landslide occurence such as elevation , slope gradient, slope aspect, slope curvature, rainfall, distance fro...

BACKGROUND Both road safety campaigns and epidemiological research into social differences in road traffic injury risk often assume that road traffic injuries occur close to home. While previous work has examined distance from home to site of collision for child pedestrians in local areas, less is known about the geographic distribution of road traffic injuries from other modes. This study expl...
