Abstract:

This dataset contains latency and packet rate information with synchronized time stamps for communication between the Roadside Unit (RSU) and Onboard Unit (OBU). The Autonomous a2z LiDAR Infrastructure System was used to generate object lists at the CETRAN test track and the end-to-end latency was calculated. The LIS system and the receiving OBU system had their system clocks synchronised over NTP before the data was captured. However, since the LIS timestamp was generated on Windows 10 set to South Korea time (+9 UTC), the timestamps require a 9 hour correction by subtracting 32400 seconds to get the correct coordinated timestamp. The latency calculation was performed while taking this into account. The data was captured for 3 distinct scenarios on the CETRAN test track in addition to comparing the performance across different locations on the test track. Each scenario was executed twice. The dataset also contains timestamped position logs which can be used to analyze the communication performance at different geographic locations within the CETRAN test track. The position logs were recorded from the VUT (Vehicle Under Test).
