Validating crash locations for quantitative spatial analysis
A geographic information system (GIS) is a commonly used method for analyzing traffic accidents.
If autocorrelation exists in a map, then this violates the fact that observations are independent from one another.
The present study analyzed tourist traffic accidents in Nantou County, one of the most popular tourist areas in Taiwan for domestic and international travelers, and tabulated statistical data that were subsequently input into a GIS database to determine dangerous locations and areas where traffic accidents are prone to occur.
First, administrative regions in Nantou County were identified and kernel density estimation and repeatability analysis were performed to determine locations with high accident rates.
