    Metadata Updated: March 16, 2025

    Data provided consists of Basic Safety Messages (BSM) generated by the Trajectory Converter Analysis (TCA) tool with input from VISSIM calibrated simulations of the I-405 corridor in Seattle, Washington. The Seattle I-405 data environment includes data for a variety of network operational conditions, market penetrations of connected vehicles and communication strategies along the I-405 travel corridor.
