Love it, but I’m pretty sure you’re missing ferry routes in the NYC calculations (which are public). It also might be worth including Citibike as an optional additional method.

Re: Show HN: I built a transit travel time map
#52Is there a word/map for the transit accessibility for each point (1m^2?) on the map and drawing that? (maybe an integral of the isochrone?)
E.g. pick a point on a map, sum the area of the isochrone (30minute area? weighted sum?) to get a value at that point. Then redraw a heatmap of those points.

#53Public service announcement - these kind of maps are known as isochrone maps and they're anything but new, but are (IMHO criminally) unpopular. They're extremely helpful when house hunting. https://en.wikipedia.org/wiki/Isochrone_map
Agreed. It took weeks of researching to find this term when I was looking to optimize travel time search. Once I did, everything became easier! Ended up forking Open Transit Planner, this was back in 2015. Turned 40 minutes real estate searches into 40ms or so.
Wouldn't have helped you back then but LLMs are _spectacular_ at giving you the term that you don't really know what to google for.

#54I seems to be slowing down quite a bit after I double clicked, or maybe HN visitors coming in. Is this implemented with a Graph database?

Is your fork available somewhere cause it sounds awesome!

#56Very nice! Do you have any documentation for how to add another city or transit region?
I work on some of the rust libraries you've used. If you'd like to ask questions about rust+geo or do a show & tell, consider joining us in the georust discord: https://discord.com/invite/Fp2aape
I'm also always interested to hear new people's experience building real things with our libraries. What were the hangups?
Re: Show HN: I built a transit travel time map
#57This is super super cool! This kind of visualization is so much more useful for finding a transit-friendly spot to live than the generic TransitScores real-estate websites have. Would be nice if the frequency of bus routes could be visualized too, and hope you find a way to add more cities painlessly. Having worked in transit planning, this is really useful for network gap analysis - like finding areas where connectivity could be improved.

#58This is awesome - https://www.mapnificent.net/ is a similar project (also open source). Might be cool to collaborate on data sources?

#60Super awesome! I like how you just color roads to show time. When you calculate polygons to try and cover the whole area in some 5-10 minute bucket, you can wind up with all sorts of odd holes far away from roads. Keep it simple.
