EarthSense to monitor Oxford traffic air quality data

Air quality data specialist EarthSense is working with Oxfordshire county council and ‘connected vehicle’ company Tantalum to gain a better understanding of the impact of road traffic on dynamic air quality.

Vehicles within Fleet Services, from Oxfordshire council, are to be fitted with EarthSense’s Zephyr air quality measuring sensors that will give real-time data on both vehicle emissions and the local air quality along routes.

The data collected by EarthSense will be used to optimise traffic light control and coordination in order to manage and mitigate road congestion and pollution. The data will also feed into the county’s work with Oxford city council as it prepares for its Zero Emission Zone.

Llewelyn Morgan, service manager for infrastructure, innovation and development at Oxfordshire county council, said: “We have a special interest in projects that will help ensure that Oxfordshire is at the forefront of emerging technologies for air quality monitoring and management especially in relation to traffic emissions. Working with EarthSense and Tantalum we will benefit from research already undertaken as well as new data, and therefore understanding, obtained through the use of the EarthSense sensors.”

In addition to the use by Oxfordshire, data from the EarthSense Zephyr sensors will also be used to help Tantalum, working alongside Imperial College London, refine traffic emission models within the collaborative Air.Car project.


Using the IoT and Smart City technology the Air.Car project will deliver the ability to drive a greater understanding of vehicle pollution, while enabling the reduction of environmental impact and vehicle operation costs, the companies claim.

Solutions include a clean routing app for taxis as well as smart, fair and affordable enforcement schemes for local authorities such as Oxfordshire.

Alex Willard, head of Air.Car, said: “This is a major milestone in our project to develop services which will give power to drivers, businesses and government to reduce emissions and clean up our air. We are delighted to be working with Oxfordshire County Council and EarthSense to improve our traffic emission models. This will be invaluable in building a service advising drivers to take routes that will reduce their emissions and also their exposure to poor air quality.”

Tom Hall, Managing Director of EarthSense added: “It is essential to obtain accurate measurements in order to understand and solve air quality problems. This project will demonstrate how the best available technologies, including the EarthSense Zephyr sensors and services from Air.Car, can provide solutions to drive change for improved air quality.”
