3D Spatial Visualization Analysis of Safety Related Driving Events of Newly Licensed Teens in Proximity of Home and School

In this analysis, forty-six newly licensed teen drivers aged 14-16 were recruited from three rural high schools in eastern Iowa. There were 1,756 safety related driving errors recorded using event triggered video recorder (see Carney et al, 2010, McGehee et al, 2007). Safety related driving errors (events) and home addresses were geocoded into a local geographic coordinate system. Spatial distribution of the safety-related events were visualized in a 3-dimensional space along with 1 meter resolution of satellite imagery, detailed road network, and a digital elevation model using the available visualization facilities of ArcGIS 10. To examine the concentration of the safety related driving errors relative to the proximity of the home and school location, different radii were created around the participant’s home and school address. The safety related driving errors were aggregated in these radii and analyzed spatial variation of these events using a Chi-Square test.
