The Australian population is ageing, and an increasing number of older Australians are becoming “grey nomads”, driving long distances on high speed rural roads. While many drivers in this age range are engaging in self regulation and limiting their driving to known roads, this population are driving on highly unfamiliar roads, and possibly engaging in unfamiliar practices such as towing large l...

A project was carried out to investigate the impact of four different weighing methods on over/ under loading of forestry trucks operating in Forestry Corporation of New South Wales under two types of roads; gazetted (approved for higher legal gross vehicle weight limits) and nongazetted (standard public road gross vehicle weight limits).

This study analyzes rockfall damage t...

When driving on lower-category Dutch rural roads without any delineation, drivers are likely to drift off the road with their right-side wheels, thus incurring damage to the pavement edge or even leading to accidents. In two experiments, two types of road-edge delineation, with continuous or dashed edge lines, were compared with two control roads without lines or with only a dashed line on the ...

Since 1994, TRL in collaboration with a number of road authorities and consultant partners have been engaged in extensive studies of the performance of low volume sealed roads within Southern Africa (Greening and Gourley, 1999). The roads included in service primary and secondary roads with ages varying from thirty years old to relatively new roads and specially constructed experimental section...

This paper suggests a fast computerized method of concluding which roads are congested and which ones are vacant by automatic analyzing of ...

Aquaculture is currently responsible for an insignificant proportion of total fish production in Uganda. However, given increasing demand for fresh fish in urban and peri-urban areas, and threats to the supply of fish from natural catch fisheries there seems to be a potentially strong market for fish and fish products produced by aquaculturalists. Small-scale fish farmers that are relatively cl...
