Europe-wide traffic survey to recruit ‘citizen scientists’

LONDON-Traffic sensors are being set up in homes in five cities across Europe in a bid to learn more about traffic flow.
English academics are involved in sending out 1,500 sensors to be placed in homes in Madrid, Dublin, Cardiff, Ljubljana and Leuven. The sensors will count the number and speed of all vehicles, cyclists and pedestrians that pass them.
Prof Enda Hayes, who is helping run the survey, said getting ordinary people involved would be key to its success.
“We will be targeting certain areas but also asking for people to volunteer to have sensors in their homes,” he said.
“Our data will be uploaded to the cloud so it can be seen by anyone, be that private citizens, the local council or NGOs.
“The evidence can be used in a number of initiatives relating to things like speed, noise, air pollution, safety and active travel. Hopefully it will place citizens in the centre of the debates on these issues.”
The data gathered will be updated hourly and will be freely available for anyone to access online. The cities are being included in a project called Citizens Observing UrbaN Transport (WeCount).
It is part of Horizon 2020, a European Commission-funded research project into sustainable economic growth.
With air pollution being blamed for 500,000 premature deaths across the continent in 2018, the experts running the survey hope their results can be used to make cities healthier places to live.
Prof Hayes, from the University of the West of England (UWE) in Bristol, says the technology being used is simple, but will enable people to take control of data where they live.
The sensors will be placed in homes with a clear view of the road outside. Software inside them will analyse the speed and size of whatever passes it and determine whether it is a vehicle, pedestrian or cyclist.
“The sensor components are made by Raspberry Pi, standard hardware that’s available off the shelf. They are powered by a micro USB port,” he said.
“It will connect to the wi-fi in the person’s home, just like any smartphone or computer. “Data is published hourly but the exact location of the sensor is not given, just the road it is on.”
