Taxis to measure pollution in Stockholm

In a pilot study being carried out by the Department of Applied Environmental Science (ITM) at Stockholm University, four taxis have been equipped to measure pollution and particulate matter. Instruments fitted to the roof of the taxis undertakes measurements which are then cross referenced with the cars' GPS as they travel around Sweden's capital.

In a pilot study being carried out by the Department of Applied Environmental Science (ITM) at Stockholm University, four taxis have been equipped to measure pollution and particulate matter. Instruments fitted to the roof of the taxis undertakes measurements which are then cross referenced with the cars' GPS as they travel around Sweden's capital. According to Christer Johansson, professor at ITM, the longer term vision is for a comprehensive on-board pollution particulate measurement system using hundreds of vehicles, including taxis, buses and other vehicles, connected to the city's active traffic control so that measures can be taken dynamically to reduce congestion and environmental damage.

    The market and technology for weigh-in-motion systems continues to evolve – Mike Woof writes. for both mature and developing highway infrastructure networks, traffic densities play an important role in determining road wear and life. Monitoring traffic volumes and individual vehicle weight is crucial for ensuring roads can cope in the long term and that maintenance can be planned, while the problem of overloading can be eliminated.

Besides causing annoyance, it has significant negative health impacts on populations living close to road infrastructure. In 2002, to help counter this state of affairs, the European Parliament and Council adopted Directive 2002/49/EC relating t

    The world’s best road infrastructure project can also have the world’s worst traffic noise problem. But where to start defeating this noise pollution? Road traffic noise is one of the most obvious aspects affecting the quality of life in urban areas. To combat this, local, national and international authorities have developed initiatives to avoid, prevent or reduce exposure to noise. One of these initiatives – Life DYNAMAP – is underway by a group of researchers in Germany, Spain and Italy. The project is f

    More collaboration is needed to reduce the impact of highways on the environment, particularly air quality. The technology already exists, argue Bram Miller* and Martin Broderick* The European Environment Agency produced a report showing that a slow improvement in air quality has been observed across Europe. However, 9% of urban Europeans were exposed to nitrogen dioxide emissions in excess of the EU’s annual maximum limit in 2015. Meanwhile, associations between highways and the environment tend to be n
