>You could get the same predictive quality with a simple gaussian blur of the "historical accidents" plots (road segmentation included), it seems. I worked on a project like this for an insurance-oriented hackathon We created a heatmap from readily available historical data adjusted for traffic density, and played a sound on a mobile device when approaching "hotspots".
