Nowadays, it is necessary to apply modern techniques for the design of road networks, especially roads passing through ecosystems such as forests, in order to reduce operating costs, prevent further degradation of the environment, increase road efficiency and achieve sustainable development goals. In this paper, a new way of designing the road is presented. New design method has the ability to ...

in order to evaluate the effects of forest road on regeneration and vegetation composition in district no. 2 shafaroud, a road was selected with the length of 400 m that the altitude, aspect, slope variations and species composition were similar. five transects in right and 5 transects in left side of road, were established as perpendicular. in each transect 5, 15, 25 and 35 m distances were de...

In the lowland tropical rain forest of central Amazonia, I investigated the responses of understory bird communities to forest edges bordering a narrow (<40 m width), unpaved road. From 3681 mist-net captures, bird abundance and composition were examined at three distances (10, 70, and 130 m) from forest edge. The degree to which regrowth vegetation along forest borders reduced edge effects was...

An approach for automatic road extraction from digital aerial imagery is presented. The extraction is based on a semantic model for roads. The images are divided into different so-called “global contexts”: rural, forest, and urban. Different parts of the road model and different strategies are used in the different global contexts. In rural areas, a multi-scale approach is employed to find init...

Forest degradation in the tropics is often associated with roads built for selective logging. The protection of Intact Forest Landscapes (IFL) that are not accessible by roads is high on the biodiversity conservation agenda, a challenge for logging concessions certified by the Forest Stewardship Council (FSC). A frequently advocated conservation objective is to maximise the retention of “roadle...

With the urbanization process around the globe, traffic accidents have undergone a rapid growth in recent decades, causing significant life and property losses. Predicting traffic accidents is a crucial problem to improving transportation and public safety as well as safe routing. However, the problem is also challenging due to the imbalanced classes, spatial heterogeneity, and the non-linear r...

This study aims at quantifying the influence on the traversability of road network of road network caused by building collapse in earthquake. To this end, an analysis method on post-earthquake traversability of road network considering building collapse is proposed. First, the time-history analysis of seismic response based on the multi-degree of freedom (MDOF) model is performed for regional b...
