Monitoring the actual state and tendencies of urban air quality and its forecasting plays an important role in the environmental and meteorological research of Hungary, since it is a key element of the urban life quality and health protection. After the change of the political system in 1990, with the modernization of the industry, road…
Traffic data collection is an essential issue for road-traffic control departments, which need real-time information for traffic-parameter estimation: road-traffic intensity, lane occupancy, congestion level, estimation of journey times, etc., as well as for early incident detection. This information can be used to improve road safety as well as to make an optimal use of the…
When considering short-term prediction systems that operate in real-time and in an “intelligent” technology-based environment, the effectiveness depends, mostly, on predicting traffic information in a timely manner (Smith & Oswald, 2003). This implies that regardless of the traffic conditions met in real-time, a prediction system should not only be able to generate accurate single step…
In this paper, different artificial neural network (ANN) models for predicting the hourly traffic flow in Second Tolled Bridge of Bosphorus in Turkey is performed. Second Bosphorus Bridge has an important role in urban traffic networks of Istanbul. The prediction of the traffic flow data is a vital requirement for advanced traffic management and traffic…
City busses are main vehicles for public transport to meet travel demand of the society. They operate where urban population is very dense and release such emissions as particulate matters (PM), nitrogen oxides (NOx), carbon monoxides (CO), and hydrocarbons (HC) where the population lives (Soylu et al., 2009, Gumrukcuoglu et al., 2008, Soylu, 2007, WHO, 2003)….
Maritime law, also called admiralty law, or admiralty, the body of legal rules that governs ships and shipping. In English-speaking countries, “admiralty” is sometimes used synonymously, but in a strict sense the term refers to the jurisdiction and procedural law of courts whose origins may be traced to the office of Admiral. Although etymologically maritime law and “law of the sea” are identical, the former…
Carriage of goods, in law, the transportation of goods by land, sea, or air. The relevant law governs the rights, responsibilities, liabilities, and immunities of the carrier and of the persons employing the services of the carrier. Historical Development Until the development of railroads, the most prominent mode of transport was by water. Overland transportation of goods…
Air law, the body of law directly or indirectly concerned with civil aviation. Aviation in this context extends to both heavier-than-air and lighter-than-air aircraft. Air-cushion vehicles are not regarded as aircraft by the International Civil Aviation Organization (ICAO), but the practice of individual states in this regard is not yet settled. The earliest legislation in air law was a…
Tunnels and underground excavations, horizontal underground passageway produced by excavation or occasionally by nature’s action in dissolving a soluble rock, such as limestone. A vertical opening is usually called a shaft. Tunnels have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting water and sewage. Underground chambers, often associated with a complex of connecting tunnels and…
Lighthouse, structure, usually with a tower, built onshore or on the seabed to serve as an aid to maritime coastal navigation, warning mariners of hazards, establishing their position, and guiding them to their destinations. From the sea a lighthouse may be identified by the distinctive shape or colour of its structure, by the colour or flash pattern of its light, or by the…
