in the past, forest road network designing was mainly done for its main goals-management and exploitation. this study was performed to pay attention for multilateral goals of forest roads, especially its role in forest villages’ development, in estakhr-posht of neka (6 villages) in series 2, section 6 of neka-zalem rood forest management plan. at first, constructed forest roads and suggested ro...

Background: Several factors influence the growth in the number of road traffic accidents and the resulting death rate. Road accident scenarios can be considered in different seasons and time intervals. In the present study, the role of factors effective in the growth of the number of accidents was explored in the south of Kerman during the period from 2013 to 2017. Materials and Methods: In th...

This paper explores the traffic, land use and welfare impacts of road pricing in the Austin region, introducing planned toll roads, implementing marginal cost pricing (MCP) on main roads, applying tolls to existing bridges, and instituting a downtown tolled cordon. Different toll scenarios are examined, including fixed versus variable tolling, and tolls based on time of day, traffic, and travel...

Automatic and semi-automatic methods for the extraction of topographic information are a present research topic. Especially for topographic mapping and navigation applications road extraction is important, but still not in practice. Due to the speckle effect and the limited width of roads with respect to the ground resolution automatic road extraction from SAR imagery is rather difficult. In th...

Nitrogen dioxide (NO2) is a ubiquitous air pollutant with high concentrations particularly close to main roads. The focus of this study was on possible differences in NO2 concentrations between adult and child heights as a function of different distances from heavily trafficked roads in urban areas. Passive diffusion tubes were used to measure NO2 concentrations at heights of 0.8 m (approximate...
