Feasibility Study and Assessment of Communications Approaches for Real-Time Traffic Signal Applications Study Data

Published by US Department of Transportation | Department of Transportation | Metadata Last Checked: January 20, 2026 | Last Modified: 2020-12-30
This dataset contains raw Signal Phasing and Timing (SPaT), MAP, and Basic Safety Messages (BSM) data from the "Feasibility Study and Assessment of Communications Approaches for Real-Time Traffic Signal Applications" project in the hexadecimal string and pcap formats. The project characterizes and assesses the feasibility of SPaT messages for infrastructure-based safety applications by comparing messages received through cellular networks with those received through Dedicated Short Range Communication (DSRC). This dataset contains the raw research data collected for the project. The project's final report and supporting dataset can be found at the National Transportation Library and is linked in the references section of this dataset.
