We chose to address the issue of misinformation with the general public when it comes to the crime and its patterns in the Hartford region. Dataset which we chose for this is from the publicly available Police Incidents registered in Hartford area from 2005 till date with the time stamp. Pattern of the crime can be analyzed like e.g. Robbery incidents mainly happen during holiday season. Using the API we built a live tableau dashboard and also forecasted the drug offenses as per neighborhood.
3. Crime has patterns and can be analysed
Predicting those patterns based on the geographical characteristics and time
will help us in segregating crime zones
This makes people aware of the neighborhood
Data tells us about
Police incidents in
Hartford area
A pattern can be
identified for a region
and for a time period
Forecasting the
crime rate for
