1. Road conditions – flooding, potholes – local drivers might already know such factors and avoid such routes
2. Type of traffic (Cyclists might want to avoid heavy vehicles)
3. Crime (Avoid crime prone areas)
4. Garbage dumps (Cyclists or people on foot might want to avoid filthy neighborhoods)
1. I change my city: Citizens post complaints pertaining to a wide variety of categories such as garbage, traffic, crimes, and potholes
2. Twitter : Crawled tweets mentioning potholes, Perform NER to recognize location, geocoded the location name to get the coordinates
3. Wikipedia: Extracted bus stop names, geocoded to get coordinates
4. Satellite imagery: Segmented satellite images to get location of green areas.
Unsupervised as we have no labelled data
Used simple image processing techniques to extract a mask of the forest/ canopied areas
1. Use a spacial hash to store and retrieve information points ( pothole/ crime etc) close to a given location
2. Precompute the edge lengths in the graph for every combination of preferences (like avoid garbage but do not favour greenery)
