Sentence examples for road buffers from inspiring English sources
Thus, questions remain about the validity of results from health effects studies that use exposure surrogates such as road buffers.
The individual residence-based assignment of exposure represents a substantial improvement over most studies that have relied on central monitors or on binary road buffers combined with basic interpolation (Hoek et al. 2002; Pope et al. 2004).
Due to large proportions of building and road, Buffer 3, 4 and 5 undergo the highest temperature.
lithology, soil, slope, aspect, fault buffer, drainage buffer, road buffer and land cover were selected to represent the landslide problems of the study area.
Considering it one of the main causal factors a road buffer map was prepared with buffer zones of 200 m, 800 m, 1500 m and 2500 m. 4.
The road buffer zones are from 250 m to 1.75 km. Figure also shows the averaged profiles and the exponential potential function (ϕ RO ) model.

The road buffer factor shows high landslide activity associated within 200 m proximity (FR = 1.51) with more than 50% of the landslide area, which indicated direct impact of slope excavation for road widening in the hilly areas.
Distance from road (Road buffer): In hilly areas slope excavation for road widening is a common practice which greatly influences the slope stability and similar has been found for the present study area where landslides associated with the slope excavation are common.
With help of ASTERGDEM of 30 m resolution (source- USGS website) the drainage buffer, slope angle and the aspect maps have been produced whereas the geology, soil and fault buffer maps were prepared with the help of previous published maps (Mahajan and Virdi, 2000) and the land cover and road buffer maps were extracted with help of Google earth imagery.
