Workers in the road construction industry include asphalt plant, ground construction, and road paving workers. These individuals can be exposed to a wide range of potentially hazardous substances. A summary of levels of exposure to different substances measured during road construction is presented. In modern road paving, workers typically are exposed to 0.1 to 2 mg/m3 of bitumen fume, which in...

Pavement maintenance and rehabilitation have been neglected in Nigeria for a very long time and has resulted to maintenance backlog. Design agencies in Nigeria still use California Bearing Ratio (CBR), even though the method is outdated. An introduction of Dynamic Cone Penetration Test (DCPT) was pertinent, even though the method is relatively old in some developed countries, it has not gain mu...

The system analyzes the data and recognizes if a dangerous situation exists such as the sudden appearance of road construction sites, traffic back-ups and warnings of objects on the road or inclement weather. Drivers are warned of the precise location of the danger through warning lights integrated in the reflector posts and directly via car-to-x communication. Fraunhofer Institute for Embedded...

The aim of the work is to present results inspection foundations overpass and determine causes defects. This a particularly relevant task for countries with large extensive territory, such as Kazakhstan. area located in centre Eurasia, where many international routes between Europe Asian have crossed since ancient times until day. One main highways Yekaterinburg - Almaty (2336 km), which one tr...

Creative destruction due to new technologies causes both long-run growth and short-run business fluctuations. The creative part of new technologies pushes the economy on a higher productivity level while the destructive part implies partial obsolescence of old production units. Obsolescence due to each new technology induces an adjustment period during which growth rates are initially high but ...

Nowadays there are vocabularies or languages that describe concepts and structures of data related to traffic, but the description is just syntactic, not semantic. No vocabularies or ontologies with semantic value that give significance to concepts and their relations were found (at least up to where the search and bibliographic revision of this work took us) which we could have taken as a star...

In recent years VANets have come up as new information promulgation technology. To enhance vehicle and road safety, traffic efficiency, and ease as well as comfort to both drivers and passengers, VANets become an active area of research. In VANets, vehicle work as a node. Vehicle collect different types of information like road traffic and environmental information and transmit them to intended...

Despite all the progress in neural networks the technology is still brittle and sometimes difficult to apply. Automatic construction of networks and proper initialization of their adaptive parameters are the key factors to create robust neural networks. Methods of initialization of MLPs are reviewed and new methods based on statistical discriminants and logical rules are suggested. These method...

Nowadays the construction of conventional overhead power lines has faced several constraints, with increasing need reducing right-of-way limits, especially in urban areas, and flow within same existing lines. In this context restrictions, transmission compaction become a possible option. This work investigates how new compact line technologies influence its electrical parameters, particularly, ...
