Edmonton Speed Zone Regulations With Street-Level Attributes

Edmonton's speed zone data includes street names, speed limits, and directional information. The dataset is maintained by the City of Edmonton and was last updated in September 2024. It is governed by the City of Edmonton Speed Zones Bylaw No. 6894.

Use Cases

• Validate speed limit compliance by analyzing the `speed` and `travel_direction` fields for specific `street name full` entries.
• Map speed zone changes over time by comparing `effective_time` and `duration` values across different `jurisdiction` areas.
• Identify all streets with a specific speed limit, such as 30 km/h zones, by querying the `speed` column.
• Analyze the spatial distribution of speed zones by processing the `geometry_line` data alongside `from_street` and `to_street` fields.

Strengths

• Includes a `geometry_line` column for spatial analysis.
• Contains multiple street identifier columns (`from_street`, `on_street`, `to_street`) for cross-referencing.

Limitations

• Sample data and row count are unavailable, preventing assessment of dataset size.
• The description explicitly warns about potential inaccuracies and incomplete information.
