Tampa CV Pilot: Basic Safety Message Sample for Connected Vehicles

Tampa CV Pilot data consists of Basic Safety Messages (BSMs) generated by participant and public transportation vehicles and transmitted to roadside units. This dataset is a flattened sample following SAE J2735 and J2945/1 standards, with an added geo column for mapping. The full raw BSM data can be requested from the ITS DataHub Sandbox.

Use Cases

• Analyze vehicle dynamics and safety events using coreData_brakes_abs, coreData_brakes_brakeBoost, and coreData_secMark from 30+ available columns.
• Map vehicle trajectories and positions for geospatial analysis using the coreData_position and coreData_heading columns.
• Classify vehicle types and roles for traffic modeling using part2_suve_classification and part2_suve_cd_role.
• Study temporal patterns in vehicle communication using metadata_recordGeneratedAt and metadata_generatedAt_timeOfDay.

Strengths

• Data follows established SAE J2735 and J2945/1 standards for message structure and units.
• Includes a coreData_position column specifically added for geospatial mapping within the platform.
• Sample data is available in multiple formats including CSV, JSON, XML, and RDF.

Limitations

• Row count and total dataset size are unknown, limiting suitability assessment for large-scale projects.
• Description metadata is limited; actual data quality requires manual inspection after download.
