Fix your country first.

I went through a personal experience. I had my car stolen twice in one month. This got me thinking about how best current GPS create their routes.
A route is created but is not taken into account the degree of safety of the path to be followed, therefore we are subjected to travel on both safe places, as for hazardous locations. Based on this scenario, I wondered why a GPS system could not also tell me a kind of index of safety (based on reports or postings) on the indicated route to my final destination.
This same GPS system can also choose alternative routes based on safety.
There are many cases in Brazil and other countries in which routes were drawn and people were victims of crime because they are in hazardous locations with high rates of violence..
Is not interesting work about a safety GPS program or system that care about those points?
A program that gives us an opportunity to register via a post comment or an offense that eventually happens to us.
By means of a statistical level of violence this program could then generate a risk indicator at certain locations of the trajectory that has been determined.
This would give us the possibility of alternative safe routes according to the index of violence generated relying on posts.

Mark an area as a slum so you and other wazers can avoid it. Sorry if that's not politically correct or nice, but some places are dangerous. Eg. throwing bricks at cars, placing logs across roads, etc, to hijack you, etc.
