Products that do what Public transportation signage based on bloom filters (rough mockup) does
Hello, I was running around Germany, hectically navigating public transportation, and getting lost all the time. I noticed that every station had i platforms, each used lists of n buses (trains, whatever) arriving, each has their list of m destinations. That means I would be scanning i x n x m items just to see if I was at the correct stop. As I was nervous, for every bus that arrived, I would rescan the list of stops to double check. I began thinking how I could make a better system. Linked is a very shoddy mockup of how bloom filters could be used to allow passengers O(1) lookup time for…

This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…

Hello HN! As a long term NYC resident, I have read countless articles on ideas tweaking subway services, but always found them hard to follow without visual aid. So over the long weekend I decided to build one. It has all the basic features: trains would spawn at their origin, stop at stations, and slow down if it gets too close to another. You can also design custom routes by piecing tracks together. Have fun, and let me know what you think!

For the past few months, I've been working on a website that answers two different questions: - Where in my city have the best travel times to all the things and people I care about? - Given a listing, how far is it from all the things and people I care about? Personally this was fueled by my own frustrations when I was apartment hunting in NYC. I was frustrating to have to juggle so many Google Maps tabs when I was evaluating a listing, and it was also annoying to not have full confidence that I was even searching in the right places. I wanted to be close to work, a Trader Joe's, and a…

Hi HN! Sharing Random Airport Inspired by RandomStreetView (which I find weirdly addictive), and a passion for air travel. Probably not for everyone, but I hope some of you find it interesting! Needless to say, open to feedback! Enjoy clicking! Further reading: TECH: It's Build in React, NodeJS, with a Notion DB. The code is public on Github. It is spaghetti though ... Especially open to feedback here. DB: The db is publicly available (and editable), I can add the link in comments if anyone would like to have a look . KNOWN ISSUES: I would like to improve the design, pic loading performance…

I made a public transport route planning program that's capable of planning journeys across Europe or North America! There's only one other FOSS project I know of (MOTIS/Transitous) that can do transit routing at this scale, and in the testing I've performed mine is about 50x faster. I've spent a few weeks on this project now and it's getting to the point where I can show it off, but the API responses need a lot of work before they're usable for any downstream application. Example query (Berlin to Barcelona):…

I just redesigned an old (1 year) project and would appreciate any feedback. The site has no real purpose other than allowing you to explore the large amount of imagery gathered by Google. You can make it less random by choosing a country, or indeed any geographical area (cities etc.) http://www.mapcrunch.com Thanks

Hello! I built a map that generates a heatmap of the most convenient meeting spots between several people, based on public transit travel times. Move the markers anywhere in the map; all cities with sufficient transit data are supported!

Over the past week I built a project to let people self-host an entire maps stack so they don't have to send data to the big G. Right now it includes a base map, geocoder and directions server. Currently only bicycle directions are supported, and I'm only hosting tiles for Seattle because I'm unemployed and can't afford to host data for the whole planet. Check it out! https://maps.ellenhp.me/ https://github.com/ellenhp/headway Ultimately I'd like to really focus on transit routing (not implemented) but I'll probably throw a driving mode in there too.

I've been tracking public transport data in NZ for a couple of years now, and have now built a site for its display. Public transport is quite a contentious issue here; what's better than to inform decisions with data? I’m posting this to ask some switched on people what the best step going forward for would be for this project. If someone was building a similar site for your city, what would you want to see? https://github.com/allister-grange/missinglink
