Yunex Traffic to install Zephyr® air quality monitors across Liverpool City Region

Liverpool City Region (LCR) Combined Authority has awarded a contract to Yunex Traffic to supply and install 37 Zephyr® air quality monitors, and to maintain them for a period of five years.

The monitors will be installed in 37 existing traffic signal locations across the six authorities, with the option for a further 10 to be installed if required. The monitors will integrate with the existing Yunex Traffic Stratos traffic management and control systems of local authorities in the City Region, which will enable trends in environmental data to be reviewed and analysed. The information will also be used to provide timely interventions and enable strategies to be implemented based on real time pollution, temperature and humidity data, as well as the prevailing air quality levels.

Wilke Reints, Managing Director, Yunex Traffic in the UK, said: “Following the launch of our air quality monitors at the end of 2020, we are delighted to add LCR to our growing user base, following similar installations in Reading, Warrington, Bedford and Cardiff.

“Air quality has become a real priority for local authorities, but to fully understand the impact of traffic and any strategic interventions, it must be constantly monitored and measured. Zephyr® and Stratos combine to provide a powerful solution that can help authorities improve air quality, enabling traffic management strategies to be implemented, based on real-time data.”

Using innovative technology, the Zephyr® sensor has a replaceable cartridge system and active sampling mechanism to measure in real time nitrogen dioxide (NO2) nitrogen monoxide (NO) and ozone (O3), as well as particulate matters PM1, PM2.5 and PM10. Carbon monoxide (CO), hydrogen sulphide (H2S) and sulphur dioxide (SO2) can also be measured, if required.
