To briefly summarize the analysis results,
Kernel density estimation reveals that signal violation hot spots are highly concentrated in specific areas, whereas centerline violations exhibits a more dispersed pattern throughout Seoul.
The LISA analysis illustrates that the fewer cluster are observed in the signal violation map, while both results highlight a significant high-high concentration in Gangnam-gu.
Lastly, regression analysis demonstrates that the signal violations lead to a larger number of traffic accidents and casualties compared to centerline violation.
