Data quality

Every figure on this platform comes from a city that measured it and a review process that checked it. This page explains how data is validated before it is published and how quality is communicated to users.

How data is validated

A city is approved before it can publish anything. New cities joining the platform are validated by the ODP Administrator, who also cross-checks their data for consistency with the rest of the platform. Living lab data is displayed in the platform but only validated data is used in the data analysis and impact assessment results. The validation process is designed to ensure that the data is accurate, complete, and reliable.

  1. 1
    City Submission
    A Living Lab data editor enters KPI values, policy measures and modal split figures for a given reporting period.
  2. 2
    Format and data check
    Values are checked against the data type, unit and expected range defined for each KPI in the SIEF framework, and the required fields needed to compute it are verified.
    Automatic checks on submission form.
  3. 3
    Administrator review
    Values are compared against known ranges and against the city's own earlier submissions to surface anomalies.
    Contacts the city editor if necessary.
  4. 4
    Validation & publication
    The Administrator confirms the data submitted and validates the city.
    Data feeds the impact analysis results

How to read the data

A short discipline that covers most of the ways platform results get over-read.

  1. 1
    How much evidence?
    Look at the evidence strength badge. Limited means few cities stand behind the number.
  2. 2
    How old is it?
    Check the validation date. Older data may not reflect current conditions in that city.
  3. 3
    Does the context match?
    Compare transport mix, population and regulatory setting. A measure that worked elsewhere may not suit yours.
  4. 4
    Whose priorities?
    For any ranking, confirm which stakeholder weighting produced it and try again with the other perspectives and weights.
The bottom line

Platform results are decision support, not prescriptions. Local feasibility studies, stakeholder engagement and regulatory requirements remain essential inputs to any mobility planning decision.
