# A Method of Selecting Automated Driving Service Sections Considering Spatial Influence Factors
## 5 Validation
### Results of Validation  
The result of selecting the automated driving car-sharing service section performed in the second step is the yellow section in Figure 19 for level 3, and level 4 is the sky blue section. Here, as previously assumed in this study, in the case of level 4 service, it is assumed that the HD map is constructed, and all links equipped with all spatial ODD elements can provide automated driving services.  
The results of the comparison and analysis of the matching rate between the selected section performed in the third step and the demonstration section determined through field test areas follow. The matching rate between the planned section and the target section of the level 3 automated driving car-sharing service is approximately 91% in the num

ber of links, and approximately 94% in the distance, and the matching rate between the demonstration section and the planned section is more than 81% in the number of links and more than 70% in the distance.  
The matching rate between the planned section and the target section of level 4 is 100% consistent in both the number of links and the distance, and the matching rate between the demonstration section compared to the planned section is about 74% in the number of links and more than 84% in the distance.  
Here, the target section is the entire demonstration section, including vulnerable user protection zones that must be legally driven in manual mode within the test bed. The planned section is the selected section by the method proposed in this study, and the demonstration section is the section finally confirmed through actual field tests. The results of the comparative analysis of the matching rate are presented in Table 8.  
The automated driving car-sharing service section selected through the proposed method is shown in yellow for level 3 and red for level 4, as shown in Figure 20a. The demonstration section in Jeju ASTC, which was confirmed after the actual driving test, is shown in Figure 20b. Here, the yellow is the section where level 3 should be driven, and the red is the section where the service is available for level 4. The green is the section where the automated driving service is not possible because the HD map cannot be constructed.
