Air pollution is due to roadtraffic an inevitable outcome of internal combustion in engines of vehicles and some other processes. Air near the roads is more polluted with some pollutants, such as carbon monoxide, nitrogen oxides, ozone, particulate
matter and some others. Monitoring the air quality is a key issue, when one wants to estimate environmental impacts of the roadtraffic. The article shows a method of passive samplers for air quality monitoring along different roads in the area

In view of the large and increasing roadtraffic fatality burden in South Africa, this study describes the risk of fatal roadtraffic injuries according to population and rural-urban characteristics in the country between 2002 and 2006. There were
micro- and local climate variations is crucial when it comes to forecasting and giving warnings about different kinds of weather-related traffic disturbances. The progress of climatological research has made it possible to increase the use of road
The Swedish Road Weather Information System is a tool for road winter maintenance giving warnings about risk of slipperiness and severe weather conditions. The system is based on climatological research at the University of Göteborg. Knowledge about

South Africa faces an unprecedented burden of injuries from roadtraffic crashes, yet the distribution of these events has not been intensively studied. An examination of roadtraffic fatalities from 2002 to 2006 was undertaken with regard to a wide
range of physical, environmental and socio-economic characteristics. An area measure of violence and crime was shown to be a significant predictor of fatal accidents in addition to driver behaviour, traffic exposure and socio-economic deprivation. - (AJC)

During the winter of 1980-81 serious damage occurred to public roads in Hungary. Weather, the properties of road fill material, the traffic of heavy vehicles and the quality of pavement have been proved to be major factors influencing the extent

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
, and provide the process-based understanding necessary for planning, improved road design and mitigation.

The AA. use rainfall simulation to investigate sediment production associated with one common maintenance practice in northern Thailand, and to study sediment detachment by motorcycles and pickup trucks on unpaved roads. Additionally
they incorporate physical property measurements, road usage information and simulation results to determine links between sediment production on roads and interstorm preparation. The AA. focus on processes that determine sediment production during typical seasonal

Diminution du trafic routier ? Quelles conséquences déduites par l'aménagement régional pour son réseau routier fonctionnel. L'exemple de la Thuringe centrale.
Drawn on a case study in the central Thuringia planning region, the analysis focusses on demographic and other reasons for a partial decrease in the traffic volume. The report notes, that the decline is confined to sparsely populated rural areas
; however, routes of European significance will experience a strong future increase in transport. The AA. conclude, that regional planning should no longer call indiscriminately for the expansion of all road categories, but rather take into account
the actual developpement of traffic volumes. - (IFL)
