Speed Check Sign Vehicle Counts and Speed Bins

Data from a single radar-based Speed Check Sign (DFS041) in Edmonton, accumulated and reported in 15-minute intervals. The City of Edmonton's data.edmonton.ca platform provides records of vehicle counts within specific speed bins, capturing both the highest and slowest speed detected per vehicle. The dataset was last updated on March 31, 2026.

Use Cases

• Analyzing temporal speed patterns by aggregating `Vehicle Count for Log Interval` and `Bin Number` across `Log Timestamp`.
• Assessing speeding prevalence by filtering records using the `Bin Over Speed Limit Flag` and comparing `Speed Range for Bin` to the posted `Speed Limit`.
• Modeling vehicle speed distribution by examining counts in `Vehicle Count at Highest Speed Detected` and `Vehicle Count at Slowest Speed Detected` across the ten speed `Bin Number`s.
• Evaluating sensor operation and detection range by reviewing the `Minimum Speed Detection Setting` and `Maximum Speed Detection Setting` parameters.

Strengths

• Granular 15-minute reporting intervals for detailed temporal analysis.
• Captures two speed measurements per vehicle (highest and slowest detected).
• Data is structured with 17 distinct columns describing speed, counts, location, and device settings.

Limitations

• Unknown total row count and dataset size.
• Data is from a single sensor location (Site ID DFS041), limiting geographic scope.
• Radar-based detection can only track one vehicle at a time, potentially missing data in dense traffic.
