Municipal Street Centerline Network with Traffic Attributes

Street centerlines represent the dedicated right-of-way for roads, forming a linear network segmented at intersections. The dataset includes attributes like street names, traffic direction, and classification. It is provided by data.calgary.ca and was last updated in April 2026.

Use Cases

• Modeling traffic flow and routing by analyzing the ONE_WAY and CTP_CLASS attributes.
• Assessing road network completeness and connectivity using the SEGMENT_ID and intersection-based segmentation.
• Categorizing street types and ownership for infrastructure management based on STREET_TYPE and OWNERSHIP columns.
• Tracking changes to the road network over time via the MODIFIED_ATTRIBUTE_DT and MODIFIED_GEOMETRY_DT fields.

Strengths

• Contains specific attributes for traffic management, including ONE_WAY and CTP_CLASS.
• Includes timestamps for tracking data modifications (MODIFIED_ATTRIBUTE_DT, MODIFIED_GEOMETRY_DT).
• Data is current, with a listed update date in April 2026.

Limitations

• Sample data and total row count are unavailable, making volume assessment impossible.
• Geographic coverage is implied but not explicitly stated, potentially limiting generalizability.
