Roads and vehicular traffic are among the most pervasive of threats to biodiversity because they fragmenting habitat, increasing mortality and opening up new areas for the exploitation of natural resources. However, the number of vehicles on roads is increasing rapidly and this is likely to continue into the future, putting increased pressure on wildlife populations. Consequently, a major chall...

While common digital road network graphs are able to represent real-world street network topology relations quite adequately, they are highly generalized with regard to the composition of a road. Irrespective of their actual number of lanes, roads are shown as just one single line. As many intelligent transportation systems (ITS) applications require or provide lane-specific data and services, ...

In evaluation of annoyance level due to road traffic, many criterions of noise exposure and degrees of basic adverse effect have been proposed through composite numerical values. In the present study procedures and units proposed by various AA. are recognizded and mathematical prediction models which correlate the influence of traffic density, composition, speed and geometry of road on emitted ...

The 53.1 acre Stone Road Retail property, located on the northeast corner of Edinburgh & Stone Road in Guelph, is comprised of the following: 9.9 acres Edinburgh Market Place constructed in 1996; 6.4 acres zoned service/commercial, 9 acres high density residential and 27.7 acres institutional/research park. The 9 acre property, leased to Richmond Properties Ltd is comprised of private sector re...

Traffic calming is a useful way of controlling speeds where it is unnecessarily excessive and inappropriate for the place and uses in the surroundings, (Taylor et al, 2000). There are high incidents of road carnage in Masvingo urban and its peripheral areas despite the constructed traffic calming measures.The rationality of traffic calming measures was based on the need to improve safety and en...

In this paper, we rely on the theory of marked point processes to perform an unsupervised road network extraction from optical and radar images. A road network is modeled by a Markov object process, where the objects correspond to interacting line segments. The prior model, called "Quality Candy" model, is constructed so as to exploit as far as possible the geometric constraints of this type of...

This paper shows, with experimental traffic data from a 4-mile long congested road, that traffic delays and vehicle accumulations between any two generic observers located inside the road section can be predicted quite accurately from the traffic counts measured at the extremes of the section. Predictions can be made with a streamlined version of the kinematic wave theory that does not rely on ...

It is one of the important ways for GIS data updating based on map generalization. This paper analyzes the main steps for road data updating based on map generalization. As the core of this updating process, matching method considering the levels analyses and selective omission based on mesh density are developed. The approach for road data updating based on these two tools is proposed, which i...

Driver support systems of intelligent vehicles will predict potentially dangerous situations in heavy traffic, help with navigation and vehicle guidance and interact with a human driver. Important information necessary for traffic situation understanding is presented by road signs. A new kernel rule has been developed for road sign classification using the Laplace probability density. Smoothing...

stabilization, alter and improvement of engineering properties of soil are for providing predetermined goals. the most important aim of soil stabilization is increasing long term soil strength, but in very wet and loos lands the other aim of soil stabilization, is to decrease plasticity characteristic of soil, which are tested by atterberg limits tests. since the road soils of namkhane district...
