Liberty Bell - Smart Survey System for Clever Cities

Liberty Bell is a low cost, technical solution that simplifies the gathering and centralisation of qualitative data about the movement of bicyclists and pedestrians through a neighbourhood, campus, public amenity or access to different modes of transport.

We need to understand the issues that make people feel unsafe or be unsafe, makes them happy and comfortable while bicycling and walking. Understanding the issues is the first step in addressing the needs of cities to get more people out of cars and moving on foot or on bicycle.

  • Lack of qualitative bicycling data limits the municipality’s ability to identify safety problems and perceptions. 

  • Liberty Bell captures often undetected or under-reported data, the ‘near-miss’ incidents that scare bicyclists.
  • It is important to be able to audit a neighbourhood from a point of view of pedestrians and in particular across all demographics.
  • Liberty Bell pinpoints the exact spots where people are having problems while they walk or bicycle in cities.
  • 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 bicycle in their communities.

Auditing & Issue Reporting System

  • Low-cost technical solution to gather qualitative data about the bicycling and walking environment

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

  • Customised Interface to meet a municipality's requirements.

  • Audit records can be filtered, sorted and cross-referenced against anonymised data.

  • Great efficiencies in the recording and centralisation of actionable, real-life issues, shortening the complaint-resolution loop time.

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.

Sarah Scannell, Dublin City Council. Cycling & Walking Promotion Officer


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.

Edel Kelly, Senior Executive Transport Planner, Dublin City Council


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.
