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...

Congestion roads can cause many unwelcome results like making people late to work; deliveries do not arrive on time and more. One way to tackle this annoyance is letting the driver know which roads are congested, so they will be able not to go through them. This paper suggests a fast computerized method of concluding which roads are congested and which ones are vacant by automatic analyzing of ...

F the early 1900s to the late 1940s, road networks in South Australia were developed on the rectangular grid system as an extension to the original planning of early towns and villages. With the advent of the automobile and sealed pavements, most local government authorities constructed a sealed central strip approximately 6 meters wide with wide footpaths and verges around existing street tree...

polymer application for the improvement and modification of the bitumen used in roads surfaces has expanded in recent decades. the roads engineers and constructors, therefore, have used the modified bitumen in asphalts helping in this way to increase roads and pavements service life and improving the durability of the roads and asphalts. the bitumen used in asphalt mixture constitutes only a lo...

Roads and railways are in a sense the arteries that keep the lifeblood of the economy flowing. Approximately 70 percent of freight moves by road in South Africa and it is growing by approximately four percent per annum. Data and information on heavy vehicle (HV) volumes and axle masses are therefore indispensable to road authorities for design and maintenance purposes. Heavy vehicle data from t...

As road networks and traffic volumes increase, road-effects on animal populations are becoming more prevalent. Our goal was to identify herpetofaunal crossing hotspots on roads and to use this information to prioritize deployment of mitigation efforts. Our focus was New York State where in a collaborative effort between ecologists and the New York State Department of Transportation we synthesiz...

Roads have been associated with decreased reproductive success and biodiversity in avian communities and increased physiological stress in adult birds. Alternatively, roads may also increase food availability and reduce predator pressure. Previous studies have focused on adult birds, but nestlings may also be susceptible to the detrimental impacts of roads. We examined the effects of proximity ...

BACKGROUND The 5(th) Iran National Development Plan, 2011-2015, has emphasized on expansion of rural asphalt roads. This article aims to illustrate the trend of deaths caused by rural road traffic crashes (RTCs) and its association with length of the rural roads in Iran. METHODS We carried out a retrospective analysis on secondary data for the period from 2005 to 2010. The Iranian Forensic Me...
