An Alberta Official Statistic describes the physical condition of Alberta's highways using the International Roughness Index (IRI). The average IRI value is calculated over every 50 metre segment and further averaged over one kilometre sections. This information is used to assess and sustain the quality of the paved highway network.
Use Cases
- Assess pavement quality for maintenance planning based on International Roughness Index measurements.
- Model life cycle costs of highway infrastructure based on road condition data.
- Analyze traffic efficiency impacts based on road roughness assessments.
- Plan rehabilitation schedules for highway segments based on averaged condition data.
Strengths
- Data is an Alberta Official Statistic, indicating a formal government source.
- Condition is measured using the standardized International Roughness Index (IRI).
- Data is aggregated at two spatial scales: 50 metre segments and one kilometre sections.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
