SafeWalk: Personalised Safe Route Recommendation App

SafeWalk is a web application designed to provide pedestrians with safe route recommendations based on their preferences on the crime type they want to avoid. The app integrates with Google Maps API to display an interactive crime map and calculate the safest route between two locations, considering user-specified crime risks. The current crime data was in Tower Hamlets, London, gathered from police.uk.
