  • Know About Tunnel and Environmental Monitoring

    Building a house may take a few months. Someone who has ever supervised the construction of a house must be aware that there are so many activities which are done for it. Now, think about the large construction projects. The roads, flyovers, railway tracks etc. we use today are result of rigorous hard work and planning undertaken by different construction companies. A large number of decisions ...

  • Case study - Filming breakout noise from café and concert venue

    Problem A combined bar, bistro and concert venue in the city center has been renovated with a great emphasis on acoustic noise dampening. Nevertheless, the venue is still getting complaints from neighbours close by due to breakout noise from the location, especially during late night concerts. The establishment consists of a bar and bistro on the ground floor, with the concert venue on ...

  • Case study - Measuring impact of traffic noise in apartment living room

    Problem An apartment on the ground floor of a two story house in the city lies close to a busy road. The living room in the apartment is facing the road, and the inhabitants are bothered by traffic noise, especially in the morning and the afternoon, when the traffic is the heaviest. Traffic noise could be clearly heard when standing in the living room. The facade facing the city ...

  • Traffic emission effects on ambient air pollution by PM2.5–related PAH in Upper Silesia, Poland

    The ambient concentration of particle–bound polycyclic aromatic hydrocarbons (PAHs) was investigated in two industrial towns in Upper Silesia, Poland. The 24 h samples of PM2.5 (particles with aerodynamic diameter ≤ 2.5 µm) were collected simultaneously at busy roads (or crossroads) and at an urban background site. Additionally, the samples were collected during the heaviest traffic density (rush ...

  • Performance evaluation of a general finite line source model for NO x concentrations obtained from a motorway in Ireland

    The relative performance of a general finite line source model (GFLSM) is assessed using measured NO x concentrations obtained adjacent to an urban motorway using CEF and HEF. The predicted concentrations are compared with monitored concentrations obtained over a continuous sampling period of one year. Statistical and graphical analyses of the monitored and modelled data are employed to ...

  • Assessing the accuracy and reliability of freeway traffic monitoring stations using GPS probe vehicle speed data

    Freeway performance measures are extracted from Traffic Monitoring Stations (TMS) which gather traffic volume and speed data. Reported freeway speeds are usually aggregated over periods of 20 or 30-second or 1, 5, or 15-minute by traffic agencies. This paper examines the accuracy and reliability of reported TMS detector speeds. The study compares speeds collected by GPS-equipped probe vehicles ...

  • Traffic noise assessment at National Highway 28 in India using FHWA model

    Federal Highway Administration's Traffic Noise Model (TNM) versions 2.1 and 2.5 have been analysed to determine their functionality and accuracy in the Indian context. Each of the resulting changes between predicted noise levels and observed noise levels are analysed, and the agreement diagram is developed between observed noise levels with predicted noise levels. During the measurements, traffic ...

  • Exposure of educational institutions to traffic-induced noise at Chittagong City, Bangladesh

    The amplitude and intensity of traffic-induced noise at the environmental setup of the educational institutions in Chittagong City, Bangladesh were investigated. Average maximum and minimum sound levels in the study area ranged from 65.46 to 82.24 dB and 60.63 to 70.89 dB, respectively. Noise at all the studied educational institutions exceeded the safe limit (45 dB) as prescribed by the ...

  • Daily variation of traffic emissions in Athens, Greece

    In this work, the emissions of four pollutants (CO, Benzene, NOx and PM10) during a working day were estimated and presented in main avenues of Athens, Greece with the aid of the COPERT methodology. The data used as input to the COPERT III was collected through a measuring campaign every 15 min and lane for the time period 07.30-17.30 of a weekday. The results revealed the CO, Benzene, NOx and ...

  • SafeSeaNet and traffic monitoring of ships and dangerous or polluting goods in maritime transport within the European Economic Area

    The European Union (EU) has established an extensive vessel traffic monitoring and information system with a view to enhancing the safety and efficiency of maritime traffic. This new information system will be mandated in most ships and provide the EU Member States and the European Commission with various information pertaining to cargo and traffic routes. The information system requires ...

  • Road traffic noise in downtown area of Tehran

    Noise pollution is by now worldwide recognized as a major problem for the quality of life in urban areas. Vehicular traffic is the most important source of the environmental noise pollution in these areas (Zennin et at., 2001; Suksaard et at., 1999; Arana and Garcia. 1 998. The increasing in the population and in the number of circulating vehicles has led to an increase in the noise pollution but ...
