- Challenge: operationalise data
- Challenge: make locally specific
- Travel behaviour data
- Route network data
- Existing infrastructure (road widths, traffic, future possibilities)
- Road safety data
- Air pollution data
- Crowdsourced data

"The PCT is a brilliant example of using Big Data to better plan infrastructure investment. It will allow us to have more confidence that new schemes are built in places and along travel corridors where there is high latent demand."
"The PCT shows the country’s great potential to get on their bikes, highlights the areas of highest possible growth and will be a useful innovation for local authorities to get the greatest bang for their buck from cycling investments and realise cycling potential."
Included in Cycling and Walking Infrastructure Strategy (CWIS)

Aim: tackle the challenge that cycling uptake is often limited by infrastructural barriers which could be remediated cost-effectively, yet investment is often spent on less cost-effective interventions, based on assessment of only a few options.
