And in some places where everything else has been given over to malls, parking lots and roads, roadway edges are the only remaining area for vegetation; the Transportation Department said they should be maintained in as natural a form as possible.
Estimated traffic densities decrease from traffic-volume-dependent values at roadway edges, to zero at perpendicular distances from roads exceeding the defined buffer widths.
Traffic densities were calculated on a 20 × 20 m grid using the kernel density plotting feature of Spatial Analyst in ArcInfo GIS 9.1 (ESRI), which effectively caused the densities to decrease from volume-dependent values at roadway edges to zero at 500-m perpendicular distance from roadways.
The building stands at an intersection of busy roadways at the edge of the Olympic park, a short drive from the city center.
Time seems to have forgotten Columbia Street, a tattered roadway at the western edge of Cobble Hill where ghostly trolley tracks and Belgian blocks that once paved the road can still be found poking through the worn asphalt.
In Texas in 2002, seven people were killed when a car slipped off a sharp edge of roadway and onto the shoulder, causing the driver to overcorrect into the path of a minivan.
The overlap was eliminated when NY 5 was moved onto a new roadway located along the edge of Seneca Lake.
The state road network contains a surface width variable that was used to create an edge of roadway buffer, which was visually verified for accuracy using the aerial photography layer.
To evaluate the relationship between specific environmental gradients and plant species richness, we measured proximity of each 1,000-m 1,000-m nearest ploth edge, paved roadway, wator source (dug ponearestrainage ditch), and human dwelling using high-resolution color orthopatchs of our study aredgeOGRIpaved6; Lucas County Aroadway04) imported into ArcGIS 9.1.
It was a 12-hour, teeth-clenching, hair-raising ordeal of dodging tire-blowing potholes and edges of roadway that crumbled into precipices.
