Physical Condition of Provincial Highway Surfaces, Alberta
This Alberta Official Statistic describes the physical condition of Alberta’s highways. The International Roughness Index (IRI) is used to measure the roughness of roads and is used as a sole measurement to categorize overall physical condition. The average IRI value is calculated over every 50 metre segment of the Alberta highway network. This detailed data is further averaged over one kilometre sections to provide an assessment of condition. This information is used to assess and sustain the quality of the paved highway network, in support of efficient movement of commuter, business, commercial, and pleasure traffic. The preservation of pavement quality through regular rehabilitation reduces the total life cycle cost of the highway system, improving return on investment for Albertans.
