Data has been all over the media recently, from the Cambridge Analytica scandal to the upcoming changes to data protection rules. And here at the Urban Transport Group we’ve been talking about transport data for some time: our Getting Smart on Data report identifies some of the issues and barriers for transport authorities to capitalise on emerging data sources, and our Data Hub and associated Number Crunch report analyse trends in the transport sector.
The Institute for Transport Studies (ITS) at Leeds University recently held a workshop exploring how new and emerging data sources can help to support policy making in relation to transport, health and air quality – connections we at UTG have been exploring. Health has been rising up the transport policy agenda in recent years, accelerated by the forward thinking Healthy Streets approach emerging from Transport for London. And air quality is a pressing challenge for city regions, as they are mandated by Government to reduce levels of air pollution in the shortest possible time frame. The recent joint inquiry by four House of Commons Select Committees into the Government’s failure to improve air quality in the UK shows just how serious this has become.
The ITS event included outputs from the EU Horizon 2020 project ‘EMPOWER’, which explores how people can be encouraged to make more sustainable transport trips through incentives. This has been trialled in Newcastle, along with six other European cities, using their ‘Go Smarter’ App, and has generated positive results for participants and useful data and insight for the City Council.
Challenges yet opportunities
All of this got me thinking about the role of transport authorities, the issues they face, and the opportunities data presents for them:
- Local and city region authorities can undoubtedly benefit from this deluge of data, but often lack the resource and capabilities to deal with and fully capitalise on large volumes of data that are coming from these new and emerging sources.
- Data quality remains an issue even where you have transport tracking data, as entries can be missed where participants turn off trackers. However, tracking data can be really useful for filling in the gaps in other data sets, such as trip lengths for smart card journeys made with only one tap in or out.
- The focus so far has largely been on personal travel and exposure to air pollution. Our recent report ‘White Van Cities’ showed that vans now make up 15% of traffic in urban areas and contribute 30% of harmful NO2 emissions – yet we know little about the cause of this rise in van traffic, for example, what’s in these vans. We need to examine ways of using new and emerging data sources to explore non passenger transport as well.
- Making the case for investments in transport, which deliver benefits for health, can be challenging, but there are ways to push the agenda forward. Newcastle City Council has established a Healthy Streets Board which will help to deliver transport and health improvements.
So what are we doing at UTG?
Following our 2016 Getting Smart on Data report, we set up a group to look at some of the challenges facing transport authorities relating to emerging data. These include:
- Sharing and integration;
- Ownership and privacy;
- Quality and standards; and
- Skills, capabilities and capacities.
We have also developed our own online, interactive Data Hub, which brings together a range of data sources on a host of transport topics and allows you to generate your own bespoke analysis, graphics and charts.
On health, we are working with public health and transport expert Dr Adrian Davis to renew and re-launch the Health and Wellbeing hub on our website, with the aim of being the UK’s best online resource on the connections between transport and health.
We are also focusing on promoting the Healthy Streets approach, pioneered by Transport for London, outside of the capital. The brainchild of public health and transport specialist Lucy Saunders, Healthy Streets is a system of policies and strategies to deliver healthier, more inclusive cities where people choose to walk, cycle and use public transport. As part of this, we will be looking at developing resources and learning opportunities as well as sponsoring the 2018 Healthy Streets conference, on 12th October.
