Overview

Using the data found on the San Diego Regional Data Library related to crime incidents from 2007 - 2013 we were able to develop an algorithm to rate neightborhoods based on crime rate. Using an internal threshhold we determine if the neighborhood is unsafe and users should use caution at certain times of the day or night. Using the Gimbal Framework we then create a geofence of the area. Our supplemental Android application will notify users via Google Cloud Messaging if they enter one of these areas and provide them with tips to avoid crime.
