Despite the efforts of driver’s training and other safety programs to make U.S. highways and roads safe, thousands of U.S. citizens are killed each year in traffic accidents that could have been prevented. A similar problem exists in the U.S. Army where several hundred soldiers have been killed in the last decade in preventable combat vehicle accidents while on operational deployments around th...

There are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of China lands which are facing serious problem of desertification. Theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofNortheast China, North central china and most of northwest china. Biological methods are theultimate way for drift sand stabilization and a fu...

Research for advanced traveler information systems (ATIS) has been focused on urban roads. However, research for short-term traffic prediction on all categories of highways is needed, as highway agencies expect to implement intelligent transportation systems across their jurisdictions. In this study, genetic algorithms were used to design time delay neural network (TDNN) models as well as local...

We investigate the effect of lane kilometers of roads on vehicle-kilometers traveled (VKT) in US cities. VKT increases proportionately to roadway lane kilometers for interstate highways and probably slightly less rapidly for other types of roads. The sources for this extra VKT are increases in driving by current residents, increases in commercial traffic, and migration. Increasing lane kilomete...

The article presents an analysis of the company's competitiveness engaged in road construction works federal highways segment, including a market with its dynamics and limitations, as well study concentration level using coefficient index, competitor companies characteristics, used methods for assessing (complex differential methods) assessment results. object is company stock corporation "Road...

The nation’s network of highways plays a vital role in the U.S. economy; private commercial activity and people’s daily lives depend on that transportation infrastructure. In 2007, the public sector spent $146 billion to build, operate, and maintain highways in the United States. About three-quarters of that total was provided by state and local governments. One-quarter was provided by the fede...

Linear infrastructure such as roads, highways, power lines and gas lines are omnipresent features of human activity and are rapidly expanding in the tropics. Tropical species are especially vulnerable to such infrastructure because they include many ecological specialists that avoid even narrow (<30-m wide) clearings and forest edges, as well as other species that are susceptible to road kill, ...

Introduction: Motorcycle accidents on federal highways cause material and emotional damage are a serious public health problem. Objective: To characterize the epidemiological profile of motorcycle in State Ceará, Brazil. Method: Longitudinal, descriptive, documentary, quantitative comparative study based secondary data obtained from Federal Highway Police database traffic Ceará occurred during ...

Two groups of 26 lambs were transported for 15 hours either on smooth highways or on rougher secondary roads. Nine of the animals in each group were monitored for heart rate and the plasma levels of cortisol, creatine kinase and lactate dehydrogenase, before the journey began, after four, eight and 12 hours and at slaughter. The pH of the meat was measured 45 minutes and 24 hours postmortem and...

Wetland ecosystems, particularly the mangrove forest, are the primary wild habitat of heronry birds. However, urban ecosystems have become a favorite breeding habitat of these birds. To provide inputs into the habitat management for conservation of these birds, we investigated the quantitative and qualitative characteristics of nesting trees of heronry birds in the urban environment of the Nort...
