A network of 24 air quality sensors have now been activated across the Central Bedfordshire Council region, it was announced last week, providing open access, real time air quality information which can also be accessed by the public via an online map.

The sensors have been installed by technology firm Westcotec in partnership with manufacturer Airly and, it is hoped, will make it possible to dynamically re-route traffic away from pollution hotspots.

“There is widespread concern regarding what can be done about poor air quality,” said Olly Samways of Westcotec. “We therefore welcome the opportunity to showcase the reliability and accuracy of the air pollution sensors and to demonstrate how the sensors can work in parallel with other technology.

“For example, we can create diversion signage that will only trigger when pollution levels are high, and which will guide specific categories of vehicle – such as heavy goods vehicles and buses – away from at risk areas at these times.”

Central Bedfordshire Council senior road safety engineer Tim Oxley said the project represents a significant step forward in enabling action to reduce exposure to high levels of pollution.

“We previously had to wait for data, meaning we were unable to make on the spot interventions,” he said. “Now, by integrating the real time data with other roadside technology, we can take immediate action that will reduce exposure to high levels of air pollution – steps such as putting traffic diversions in place.

“We believe we now have an excellent opportunity to be proactive in dealing with air pollution and to minimise its impact on people in Central Bedfordshire.”

Transportation Professional will publish a Climate Action special in its upcoming March issue.
