The goal of this study was to quantify the effect of unpaved roads on runoff and sediment production on St John, and to better understand the key controlling factors. To this end runoff and sediment yields were measured from July 1996 to March 1997
from 3 plots on naturally vegetated slopes, 4 plots on unpaved road surfaces and 2 cutslope plots. Sediment yields were also measured from 7 road segments. The results assess the effects of unpaved roads on runoff and erosion at different spatial scales
Urban form, road network type, and mode choice for frequently conducted activities : a multilevel analysis using quasi-experimental design data
In this study, the AA. adopt the principles of quasi-experimental design to collect the data, which are examined with a multilevel model in the cities of Ranstad Holland. The results indicate that urban form and network type have only a modest
An attempt is made to classify the impact of weather and climate upon air, rail, road and water transport by considering for each : climatic design and required levels of maintenance; weather sensitivity and thresholds; weather forecasting and new

Piping occurs naturally in many parts of southern Africa. In certain cases, human activity has resulted in the formation of pipes within colluvial soils of the region. Piping is developed where poorly designed backslope drainage systems have been
constructed on dispersive soils as part of road cut embankments, or where culverts debouch water onto gentle, well vegetaed slope having a high water retention and increased infiltration. - (AJC)

Focusing on the design, construction and use of England's M1 motorway, the A. traces the social and cultural geographies and histories of the spaces of motorway driving. The book takes an interdisciplinary approach, and draws on archival materials
as well as contemporary debates. Attention is drawn to ideas dating from 1920 to 1950 about a future motorway system for England, the design, construction and landscaping of the motorway, and how it has been used and evaluated in recent decades. - (HC)

Lack of studies on sand-controlling system along the Taklimakan Desert Highway brought deficiencies on design and construction. And with the lapse of time, troubles such as sand deposition on the roadbeds and erosion on roadsides came to surface
and movement restrictions. By analysing the combined system of settlements, roads, military legislation, spatial design and applied violence, the paper shows how the few hundred points consolidate into one coherent spatial system. The paper wishes to contribute
This article examines gated/gating community and the settlement complex in the West Bank. The emphasis is put on the question of mobilities in order to show how the fortressed points turn into an exclusionary web by means of separated roads
Roads, railroads, and floodplain fragmentation due to transportation infrastructure along rivers

This article examines the extent of floodplain disconnection caused by transportation infrastructure across three river basins in Washington State. It shows that a rather great proportion of the studied area is disconnected by the roads
. Relatively simple broad-scale documentation of infrastructure and floodplain disconnection has potential for guiding further study of floodplain fragmentation at multiple scales, providing an impetus for improving infrastructure design and repair and helping
This research was designed to test for vegetational edge effects along road corridors through an old-growth beech-maple forest and to discern the effects, if any, of edge age, orientation, and adjacent vegetation structure on edge composition
Designing for human behaviour: for the design and elimination of environmental spaces in the dwelling in New trends in urban planning. Studies in housing, urban design and planning.
A study of the original survey records of town plats in three southwestern Michigan counties, which shows a wide range of town and town-square designs, although all the towns were laid out in the mid-1830s. Some towns were to be square, others
linear, and others were altered to permit water-driven mills. Town squares with roads crossing through were often altered later, suggesting that those who planned the towns may have had ideas at odds with the settlers. - (SLD)
