title: Maps - Safest routes
body: <p>As a student I've learned a lot of things about graphs and algorithms running there. I know that we can use algorithms to calculate the minimum path based on distance. Also, we can use graphs with weighs, like restrictions. </p>
  
  <p>In the real world, everybody knows about Google Maps, that show us the best routes based on distance, traffic, cost. I suppose those factors, like cost and traffic are weights in the graph no? </p>
  
  <p>Well, I want to create a service/app, that makes use of the registered number of accidents per path, to calculate the safest path. In reality I think this is a restriction/weight, but my problem is : What is the API/service which allows me to add this restriction to the maps? I've searched for the Google Maps API, but it just allows users for search paths based on their restrictions (distance/traffic/travel cost) and I think it won't allows me to introduce my safe factor. </p>
  
  <p>If you know the solution please tell me, it would be awesome !</p>
