Traffic Signal Change and Clearance Interval Pooled Fund Study Utah BSM Trajectories
Listed in U.S Department of Transportation
This dataset contains timestamped Basic Safety Messages (BSMs) collected from connected vehicles operating in Utah from vendor PANASONIC as part of the ITS JPO's Traffic Signal Change and Clearance Interval Pooled Fund Study.
Description
The data includes GPS location, speed, heading, accelerations, and brake status at 10 Hz frequency. These BSMs were transmitted from vehicles equipped with aftermarket onboard units (OBUs) and have been anonymized.
The dataset supports research related to vehicle kinematics during signal change intervals and interactions with traffic signal states.
