Tampa CV Pilot: Traveler Information Messages from Roadside Units

The Tampa CV Pilot generates data from vehicle and infrastructure interactions. This dataset holds a flattened sample of Traveler Information Messages (TIMs) transmitted by roadside units (RSU) in the Tampa CV Pilot Study area, following the SAE J2735 TIM message structure. Three additional fields were added during ETL for mapping, random sampling, and time-of-day filtering.

Use Cases

• Map message locations using travelerdataframe_msgId_lat, travelerdataframe_msgId_long, and travelerdataframe_msgId_position.
• Analyze message generation patterns over time using metadata_generatedAt and metadata_generatedAt_timeOfDay.
• Identify the source roadside unit for each message using metadata_RSUID.
• Study message content sequences using travelerdataframe_content_speedLimit_sequence, travelerdataframe_content_advisory_sequence, and travelerdataframe_content_exitService_sequence.

Strengths

• Data follows a standardized SAE J2735 TIM message structure.
• Includes geospatial columns for mapping message positions.
• Contains a randomNum column for random sampling within the platform.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
