Show HN: Ossia score – a sequencer for audio-visual artists

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!

Very cool.

Sometimes when I Edit Routes and click an "<- Add" button I get the console error "Uncaught Error: coordinates must be an array of two or more positions" and the page blanks out.

Thanks - this is likely due to adding two tracks facing each other, i.e.

-->-->-- --<--<--

I'll add some logic to prevent such options from showing up.

This is sadly not mobile friendly in an amusing way; the map controls are nice and legible but they block basically the entire map. If there was a way to minimize them (perhaps automatically), this might work well on mobile.

Very cool! It would be nice to have a bit more information in the readme about the project structure and e.g. how to adapt it for other cities :)

I contract out work to MTA, specifically their AI/ innovation teams.

I'm 100% showing this to them today just for fun. They'll get a kick out of it.

I can't figure out how to add a route from Bay Ridge to Clinton in NJ. That's my wishlist subway - got to Newark Airport from Brooklyn without going through Manhattan.

Edit: Actually Clifton is in NY, and playing with Google maps there's ZERO public transport from Staten Island to NJ, except by going through Manhattan!

So my idea wouldn't help anyway, unless they extended that subway all the way over the Goethals Bridge.

As a Brooklynite I wholeheartedly agree. Unfortunately this is more of a service designer as opposed to a track designer, and it only works with existing infrastructure :(

Very nice! I thought of doing the same thing in the past!
