Data Quality Tools
Tools that measure, monitor, and improve the quality of mobility and transport data — ensuring accuracy, consistency, and reliability across datasets and systems.
What Are Data Quality Tools?
Data quality tools help organisations ensure their data is fit for purpose before it is published, exchanged, or used in analytics. They detect issues such as missing values, schema violations, or inconsistent references, supporting better decision-making and regulatory compliance.
These tools are often used by:
- Data providers – to validate and improve datasets before publication
- System integrators – to ensure data compatibility
- Authorities – to monitor data quality in National Access Points (NAPs)
Types of Data Quality Tools
| Type | Description | Example |
|---|---|---|
| Validation Tools | Check schema and rule compliance | DATEX II Validator |
| Profiling Tools | Analyze datasets to detect patterns and anomalies | Mobility data profiler |
| Monitoring Tools | Continuously track quality over time | NAP Data Monitor |
| Reference Checkers | Verify identifiers, codes, and locations | ALERT-C Reference Validator |
| Visualization Tools | Provide dashboards for data quality KPIs | Quality Metrics Dashboard |
Common Use Cases
Pre-Publication Checks
Ensure datasets meet standard and structural requirements before being published on a NAP.
Quality Monitoring
Automate recurring checks to monitor dataset quality trends over time.
Benchmarking
Compare datasets or data sources using defined quality metrics (completeness, consistency, timeliness).
Debugging and Diagnostics
Identify missing, inconsistent, or invalid data fields that affect downstream use.
