Sexual harassment is a daily concern for women in Medellín. 6 out of 10 women reported that they consider that the city is not safe for them. Due to this, is important to implement alternatives, making the city a safer place to live.This project, implements Dijkstra algorithm, which provides safer routes to the women, avoiding risk and uncomfortable situations for them. This algorithm managed to calculate an optimal path regarding either harassment risk or distance as its main source of guidance. It has an average running time of 0.17 seconds and The time complexity is O(V+E log E). We can conclude that for this project to work correctly there must be a balance between distance and harassment risk, because if there is tendency towards only one of them it can be unsustainable.
