Tampa Connected Vehicle Pilot Signal Phasing and Timing Sample

A sample of Signal Phasing and Timing (SPaT) messages transmitted by roadside units within the Tampa Connected Vehicle Pilot study area. The data fields follow the SAE J2735 standard for data frames and structure. This is a flattened sample with an added randomNum column for random sampling.

Use Cases

• Analyze SPaT message structure and content following SAE J2735 data frames to understand vehicle-infrastructure communication protocols.
• Use the randomNum column to perform statistically valid random sampling of SPaT data points for analysis.
• Study the temporal patterns of signal phasing and timing messages from roadside units in the Tampa CV Pilot deployment.

Strengths

• Data adheres to the standardized SAE J2735 data frames and structure, ensuring interoperability.
• Represents real-world data from a major U.S. Department of Transportation Connected Vehicle Pilot deployment.
• Includes a randomNum column specifically added to facilitate random sampling of data points.

Limitations

• Only a sample of the full dataset is provided; the full raw SPaT data must be requested separately.
• The specific number of rows, columns, and temporal coverage of this sample is unknown.
• Data is provided in multiple formats (XML, CSV, RDF, JSON) which may require format-specific parsing.
