Quebec Road Traffic Flow Estimates from 4,500 Collection Sites

Government and Municipalities of Québec provides a linear network of estimated traffic flows for roads and highways managed by the Ministry of Transport and Sustainable Mobility. Data is derived from a statistical estimation method applied to inputs from over 4,500 collection sites across Quebec's main roads, including annual, summer, and winter average daily flow metrics.

Use Cases

• Model seasonal traffic patterns using DJMA (annual average daily flow), DJME (summer average daily flow), and DJMH (winter average daily flow) variables.
• Analyze total traffic direction flows across the road network to identify high-volume corridors.
• Integrate traffic flow estimates with geographic data (GEOJSON, SHP) for spatial infrastructure planning.
• Compare hourly average traffic per weekday per month from available Excel files to understand peak congestion periods.

Strengths

• Derived from data collected at over 4,500 sites across Quebec's main road network.
• Includes multiple calculated flow metrics: DJMA, DJME, and DJMH.
• Offers data in multiple formats including CSV, GEOJSON, SHP, and Excel for flexibility.

Limitations

• Flow values are estimates from a statistical method, not direct sensor measurements.
• Data availability is fragmented across interactive map queries and various file formats (PDF, Excel, HTML).
• Sample data and precise row/column counts are unavailable for assessing dataset scale.
