Impediments to Effective Problem Identification
The following factors may impede effective problem identification:
- Data access restrictions.
- Inability to link automated files.
- Lack of location-specific data.
- Poor data quality.
- Reporting threshold fluctuations (variations among jurisdictions in the minimum damage or crash severity they routinely report).
- Insufficient data (property damage only, non-reportable crashes, near misses, bicycle crashes, etc.).
Planners should be alert to these possible impediments and
make appropriate adjustments when they appear.
