Liberty Bell - Understanding Active Mobility in a Community

Liberty Bell is a low cost, technical solution that simplifies the gathering of quantitative and qualitative data about the movement of people through public spaces - on foot, on a bicycle, on a scooter, through using public transport.

We need to understand the issues people experience while moving - understanding the issues experienced by people of all ages, genders and abilities is the first step in addressing the needs of cities to get more people embracing active travel.

  • Lack of qualitative data about active travel limits the municipality’s ability to identify perceptions across diverse populations.
  • It is important to be able to audit a neighbourhood across all demographics - whether public spaces are age-friendly, gender friendly, or accessible by people of all abilities and all backgrounds.
  • Liberty Bell pinpoints and maps the exact spots where people are having problems as they move through their communities. Current data gathering tools are resource intensive, inefficient and not cost-effective.
  • The perception of safety while bicycling, is a major reason why people choose not to walk or bicycle in their communities. Liberty Bell captures often undetected or under-reported data, the ‘near-miss’ incidents or priority issues for those moving on foot, on bicycles or scooters, or using public transport.

Understanding Active Travel and Public Spaces

  • Low-cost community engagement tool to gather quantitative and qualitative data about the bicycling and walking environment

  • Easy to use interfaces for age-friendly participation - from younger to older members of the community.

  • Targeted resources to problem areas. Decisions are evidence-based, making best use of public funds.

  • Exact mapped spot location directs the service request.

  • Customised Interface to meet a research project requirements - what information needs to be collected.

As Dublin Cycling Officer I see huge potential for the use of the Liberty Bell in gathering information that will help Dublin City Council understand and improve the cycling environment in our city. The pilot trial demonstrated a real enthusiasm among cyclists for using the bell as a creative and safe way of recording information on their routes and experiences as they cycle through the city.

Dublin City Council is are excited by the potential for the application of the Liberty Bell auditing tool across many sectors. From school children auditing their routes to school on foot or by bike to Local Authority Staff auditing the physical environment, we see many ways in which Liberty Bell can be used to modernise auditing techniques and to collect valuable data.

Fluidedge’s experience in software design methodologies has allowed them to deliver a really beneficial, innovative, exciting new product which will help city planners gain insights into how bicyclists experience our city.
