  • Measuring Road Traffic Noise

    As part of an overall measurement programme to monitor road traffic noise in Århus (Denmarks second largest city), the Local Authority set up a noise measurement station on one of the major approach roads to Århus Harbour. This noise measurement station continually measures noise levels and can give a round-the-clock picture of noise level variations. Like most other districts, Århus Local ...

  • 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 ...

  • Analysis of the impacts of an environmental traffic management system on vehicle emissions and air quality

    Environmental traffic management systems (ETMS) are implemented to improve air quality in urban streets. They allow for a situation-related control of light signal systems to optimise road capacities and enhance traffic flow in street sections. Therefore, they are equipped with mitigation strategies and continuously provided with traffic and air quality data. In this context, it is ...

  • Reduction of Train Noise Monitored by New Measurement Station

    With increasing passenger and freight traffic, the strengthening of the rail traffic is an important and actual issue. For sustainable mobility, the reduction of noise pollution caused by trains is essential. All involved parties agree on one claim: Increase railway traffic, decrease railway noise! Additional to two already existing stations measuring road traffic noises, ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Congestion charge = better air

    With the Government giving the green light for a congestion charge in Manchester, the floodgates have now been opened for the controversial scheme to be adopted around the country. But while there’s a lot of talk about the charge being another tax on drivers already struggling to cope with rising fuel prices, little has been said about the positive impact on the air we breathe. With concern about ...

  • AQMesh used to measure local air quality at Surrey school

    Cleves School in Weybridge, Surrey (UK) has used AQMesh to measure pollution at the primary school’s entrance. The project, led by Dr. Edward Salter over the school’s summer term, aimed to understand exposure of the children (aged 7-11) to dangerous pollutant gases, with particular interest in the levels of nitrogen dioxide (NO2) and ozone (O3). Initial findings showed that levels of ...

  • Modelling the air quality impact of industrial emissions over a valley in Southern Italy

    The aim of this study is to support decision makers and stakeholders in the management of air quality in an industrial area located in a valley in southern Italy, where neither air quality nor meteorological parameters are routinely monitored. The first phase focused on the inventory of emissions through monitored data at stacks, permissions to emit from local authorities, and life cycle ...

  • Black Carbon – the elephant in the room!

    Traditionally, ambient particulates have been measured gravimetrically according to their size. However, in this article Jim Mills, Managing Director of Air Monitors, will demonstrate that the time has come to change or at least augment the way ambient particulates are monitored and regulated. Air Monitors has supplied most of the UK's ambient monitoring network, but Jim will explain why the ...

  • Why a CO2 monitor may be needed? Where carbon dioxide leaks occur

    Do you work with carbon dioxide (or CO2) in your industry? If so, then you may need a carbon dioxide monitor to check for gas leaks that could pose a hazard to your workplace safety. Learn common scenarios where carbon dioxide can leak and see how a CO2 detector can minimize your risk.  Industries Where CO2 Monitors Can Make a ...

  • Invictus noise monitor on the right track- Case Study

    An international acoustic consultancy was engaged by contractor Balfour Beatty on behalf of the end client Network Rail in this landmark project that is revolutionising transport across London. The Project: The new rail link will help cut journey times to the heart of the capital by two thirds in some cases, passing through 37 stations and running 118km from ...

  • The silence of the lambs - Case study

    Helicopters and aircraft In this particular area there were quite a few helicopters and aircraft and these were picked up by the Invictus. “You find these days that developers are being asked for more and more studies or evidence over issues such as environmental noise, particularly in rural locations. Some would seem almost comical but it is becoming more the norm to meet planning ...

  • Accelerating with Bugatti

    When the Bugatti Owners’ Club established itself in 1929, its members didn’t really have too much to worry about when it came to issues such as road congestion and noise. But just as cars have moved on with the times so has the Club. The Club applies a strict noise level threshold for competing cars at their renowned meetings on Prescott Hill near Cheltenham, ...
