Miovision Traffic Volume Data for Cambridge Intersections in 15-Minute Intervals

Traffic sensors at city intersections count vehicles by type, such as cars, trucks, bikes, and vans, without capturing video. Data is aggregated by direction of travel, with each row representing the sum of a specific vehicle class entering and exiting an intersection within a 15-minute window. The dataset is provided by data.cambridgema.gov and was last updated on 2026-05-25.

Use Cases

• Model traffic flow patterns using timebin, entrance, and exit columns.
• Analyze vehicle type distribution across intersections using class and qty columns.
• Forecast peak congestion times for specific vehicle classes using timebin and class columns.
• Correlate traffic volume with intersection geometry using intersection id and qty columns.

Strengths

• Data is aggregated in consistent 15-minute time windows (timebin).
• Includes directional traffic flow with entrance and exit columns.
• Distinguishes between multiple vehicle classes (class).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data may be incomplete or missing when sensors are offline or being repaired.
• Description metadata is limited; actual data quality requires manual inspection after download.
