An introduction to the files.

1. Details-of-Hazards.pdf

We have defined a total of 70 hazards, which fall into four categories. This document shows the details of the hazards.

2. 智能网联汽车预期功能安全场景库建设报告.pdf

(Research on the Construction of a Scenario Library for the Safety Of The Intended Functionality(SOTIF) in Connected and Autonomous Vehicles)

This research report studies the scenario framework and architecture for SOTIF testing needs of intelligent driving, aiming to provide a reference for the development of simulation and testing software for SOTIF of intelligent driving, as well as the design of testing procedures and test cases.

Pages 7 to 22 of the document provide a detailed overview of the external hazards that lead to perception limitations, i.e., the details of visual hazards.

3. Conflicting Hazard Value Assignment Scheme (CHVAS).pdf

We have defined an assignment scheme for assigning values to conflicting hazards. By assigning values to hazards in order through this scheme, we avoid some unnatural phenomena, such as the combination of dense fog and strong light.

4. Data

NOTE1: To save space, we deleted most of the images in the dataset. But we still kept the first sample of each sub-experiment for the convenience of readers to conduct inspections.

NOTE2: Although he test dataset used in the ChatGPT4 experiment is the same as the test dataset used in the random-sampling experiment, we still listed 3 extra samples for comparison to demonstrate the results of the ChatGPT4 experiment.
