Saferoute
For BrisHack 2024 (24 hour hackathon run by the University of Bristol Computer Science Society) the brief was “Health” - one of the categories was mental health and this was my team’s entry which won us first place in the category.
Our idea was to create a route planner that would take into account the safety of the route - not just the length. If you’re travelling by yourself (especially late at night), speed might not be the priority when it comes to getting home. You might prefer a slower route that routes you around a dangerous area.
You can give it a go here - bear in mind it only works for points in Bristol (UK).
Tech
We use networkx and osmnx for routing - using dijkstra’s where the weights of each edge is a combination of time and also the number and severity of crimes where that was the closest edge.
Limitations
Currently there’s no way of the user adjusting the weights. Also it only works in Bristol as that’s the only place we have the data for.
