BACKGROUND The relationship between residential proximity to roadway and long-term survival after acute myocardial infarction (AMI) is unknown. We investigated the association between distance from residence and major roadway and 10-year all-cause mortality after AMI in the Determinants of Myocardial Infarction Onset Study (Onset Study), hypothesizing that living closer to a major roadway at th...

Background—The relationship between residential proximity to roadway and long-term survival after acute myocardial infarction (AMI) is unknown. We investigated the association between distance from residence and major roadway and 10-year all-cause mortality after AMI in the Determinants of Myocardial Infarction Onset Study (Onset Study), hypothesizing that living closer to a major roadway at th...

Traditionally, transportation engineering students have used engineering drawing techniques to manually lay out lines and curves over contour maps for highway geometric design. The design process requires numerous calculations of stopping sight distance, minimum turning radius, and curve alignments to minimize economic and environmental impact and construction costs. Students usually perform it...

A drainage roadway was constructed in the fractured zone beside an air-return roadway of a mining site. However, drainage roadways serve only one working face and are discarded after mining, thus weakening sustainable mining practices. To improve the sustainability at mining sites, this paper proposes a new drainage roadway that can serve two adjacent working faces. A schematic layout of the pr...

Current guidelines for the location and design of bus stops do not take into account air quality or exposure considerations for waiting passengers. This paper compares the exposure of transit riders waiting at three-sided bus stop shelters that either: 1) face roadway traffic, or 2) face away from roadway traffic. Shelters were instrumented with devices to monitor particulate matter concentrati...

Coal roadway driving is an important part of the underground mining system, and very common in Chinese coal mines. However, the high concentration of respirable dust produced in the blasting operation poses a great hazard to miners’ health as well as the underground environment. In this paper, based on the direct simulation Monte Carlo method, the gas–solid two-phase flow model of particle move...

With the development of coal mine equipment mechanization, wide application of “hole instead roadway” technology greatly reduces cost gas control engineering, but puts forward higher requirements for effect drainage. At present, drainage inspection boreholes is mainly evaluated by drilling field, flow rate and concentration each borehole in field are not same, which causes to be correctly maste...

This report provides interim results on the design of interfaces between automated highways and conventional street systems. The purpose here is to identify the strategic issues in interface design, and to provide preliminary analysis on just one of these issues (separation between highway entrance and exits). Future research will explore a full set of strategic issues in greater depth. The cen...

Further research has been done in order to reduce the energy consumption of the mine roadway wireless sensor nodes and prolong the lifetime of the network. On the basis of analysis and study on the existing linear wireless sensor network nodes deployment, the node distance optimization deployment scheme with sinks in the center is proposed. The calculation method for optimized distance between ...
