Driver support system is one of the most important feature of the modern vehicles to ensure driver safety and decrease vehicle accident on roads. Apparently, the road lane detection or road boundaries detection is the complex and most challenging tasks. It is includes the localization of the road and the determination of the relative position between vehicle and road. A vision system using on-b...

Despite a broad consensus that high transportation costs are a large barrier to economic development, many of the world’s poor live in rural communities without paved roads, impeding their access to outside markets and public services. Nevertheless, the impact of rural roads on economic activity has proven difficult for economists to assess. We first motivate our empirical approach by demonstra...

Roads are pervasive features of modern landscapes and have major impacts on air, land, and water quality. The United States has >6.2 million km of public roads used by >200 million vehicles (National Research Council [NRC]1997). Road corridors (road plus maintained parallel strips) cover 1% of the United States (NRC 1997) but their direct environmental impacts extend to 20% of the land surface ...

background and aim: traffic accident is one of the main causes of mortality in iran. the damage and injury caused by these accidents threatens human societies severely. rural accidents are often more severe and show harsher consequences because the operational speed is higher on rural roads and highways. world statistics presented by world health organization (who) reveal that about 25 percent ...

Rural two-lane highways are the most common road type both in Poland and globally. In terms of kilometres, their length is by far greater than that motorways expressways. They roads one carriageway for each direction, which makes overtaking slower vehicles possible only when there a gap stream traffic moving from opposite direction. Motorways express dual carriageways expected to support high s...

This paper presents an evaluation of the effects on road safety of new urban arterial roads in Oslo, Norway, and a synthesis of evidence from similar studies that have evaluated the safety effects of new urban arterial roads in other cities. A before-and-after study was made of four urban arterial road projects in Oslo. The study controlled for general accident trends in Oslo and for regression...

Poisson regression and negative binomial regression have been widely used to model the road crashes and to predict crash frequency. Zero inflated models have been shown to be a powerful tool to predict crash frequency when crash data are characterized by preponderance of zero. This paper presents the research work aiming to correlate the road traffic crash rate with road geometry and traffic ch...

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 ...
