The article describes a web application that leverages OpenStreetMap (OSM) and its Overpass API to create custom route planning based on user-defined criteria such as quietness or safety, rather than just distance. Users can select start and end points on a map, and the app calculates the route based on either the shortest path or the quietest path, with quietness being the default setting. The application uses Leaflet and JavaScript to interact with the map, while the Overpass API fetches detailed map data, including street types, which helps estimate quietness. Python libraries like haversine and dijkstra are employed to calculate distances and determine the optimal routes. The app uses Folium to display the calculated route on a map. Potential enhancements include adjusting the quietness estimation radius and incorporating additional criteria such as prioritizing illuminated paths or accommodating individuals with mobility challenges.
