## 4 Experimental Analysis
### Analysis of the Impact of Image and Text Information on Liability Determination Results
#### 4.6.1 Experiment 1  
To simulate varying degrees of subjectivity in supplementary textual information, we established the following scenarios:  
In one scenario, the driver of the white car claimed to have braked suddenly to avoid a pedestrian, arguing they should not be held liable, while the driver of the black car contended that the abrupt stop left no time to brake, thus attributing responsibility to the white car. Another scenario lacked relevant statements from either party, necessitating the model to rely solely on objective evidence and legal provisions for an independent judgment. Scenarios were also included where the text contained distracting or irrelevant details, such as mentions of the weather or unrelated items in the vehicles, to test the model's ability to filter out such information and concentrate on the facts pertinent to the accident. Additionally, cases where the text was misleading or incorrect were examined, such as false claims of deliberate actions or complications attributed to road conditions, to assess the model's ability to exclude erroneous information and maintain fairness. Furthermore, some texts presented a mixture of relevant and irrelevant content, posing a challenge for the model to extract key information while disregarding distractions. The model was also tested with complex scenarios involving multiple vehicles and incidents, such as chain-reaction collisions, and situations where sudden health issues caused a driver to lose control, requiring a balanced approach in its liability determination. Table 7 summarizes the influence of these different subjective expressions on the model's accident judgments, demonstrating its capability to handle diverse and complex scenarios with varying degrees of subjectivity. \begin{table}
\begin{tabular}{p{113.8 pt} p{113.8 pt} p{113.8 pt}} \hline \hline
**Supplementary Text Information** & **Text Information Qualitative** & **Responsibility Determination Result** \\ \hline The driver of the white car claimed that he stopped so suddenly to avoid the old man, so he was not responsible; the driver of the black car claimed that the driver of stopped suddenly and did not have time to brake, so the responsibility should be on the driver of the white car. & Article 43 of the “Road Traffic Safety Law of the People’s Republic of China” stipulates that the rear car should maintain a safe distance from the front car sufficient to take emergency braking measures. The driver of the black car failed to maintain a sufficient safe distance and failed to brake in time, so should bear all the responsibility for this accident. During the emergency braking process, the driver of the white car avoided pedestrians who suddenly crossed the road. His behavior was reasonable defense and complied with relevant road traffic safety regulations. He did not violate Article 47 of the “Road Traffic Safety Law of the People’s Republic of China” regarding stopping to let pedestrians pass. Therefore, the driver of the white car was not responsible. In summary, the driver of the black car was **fully responsible** and the driver of the white car was **not responsible**. \\ \hline \hline \end{tabular}
