Hello Mappers,I've been building this http://buz-map.com, there's a couple of 
read me's at the top. There are a stack of issues but this now looks eminently 
doable.
My pitch on all this is that people like maps. Give people a map of a transport 
network and they will follow the wiggly lines. They will notice that an island 
has a connecting ferry and a bus network (see Estonia). Envisage mountainous 
and wilderness areas and their transit geography more easily (see Sweden). Be 
able to scan an entire metropolis network to it's extremities without having to 
use trial and error (see Paris, Prague, Petersburg, Athens). And generally be 
intrigued and want to zoom in and discover. I am not having much success 
evangelizing this view with regard to a global transit map. If I can get this 
to a production state with all known GTFS, and sex up the high level areas that 
have no listed transport with a much deeper road network than you normally get 
at higher tiers, we will at least have the "intrigue me" travel map that I 
personally want. Obviously I haven't got very far with the front end. In 
particular it's not interacting very well on mobile, it's lousy in fact. I need 
help in any way shape or form available but if anyone knows how to get a thin 
line to interact in Leaflet on mobile, please suggest. I did try to paint a 
massive invisible one on top but it didn't work and I got nowhere with the 
debugger, so even help with that would be appreciated. I also want to do funky 
stuff like flipping the railways or buses to the foreground on touching. In a 
dense centre of a metropolis, being able to flip the metro or tram network to 
the top is already an important requirement. The Mapbox stuff does this but I 
haven't sussed the layers within tiles stuff and how to do it yet.
I've got a game plan to fix most of the other bugs, especially in the rail 
routing which is quite screwed right now once you zoom in. I will get the whole 
of the visible GTFS world on there, so all of USA that's available, and 
anything else that I can find. It's going to take a few months, probably most 
of the year including downtime. I say visible GTFS, as oppose to existing. 
There is an awful lot of bus data that patently exists as it's in booking 
engines, and in GTFS form if it's on Google, but isn't anywhere easily found.
What I want to investigate is to use the reduction method I have to draw 
efficient level 8 to 1 vector tiles of simplified road networks. So you can 
look at say all of India, US, Canada, China, Russia, Brazil or any area of that 
size, and get a decent view of the national road infrastructure even if I 
haven't got any bus data yet. I still will need to do some of the same simple 
reduction used for doing the detailed lower tier standard rendering of levels 
7-16, i.e. filter road classifications down once it becomes an unavoidable mess 
even with reduction, leaving only motorways for the top two or so tiers. I 
think we will get a usable, readable and "representative" map of these upper 
layers, which by default are either road light or completely vacant. The bus 
network I have in Europe, which is just a tiny subset, is messy at the high 
level, I will try to refine it, but the trains work, so I am sure motorways 
will too and we'll tune in the lower road classifications and with appropriate 
clustering radii as we proceed down the tile tree.
Any input gratefully received. Apologies for the spam of three lists, please 
respond directly unless it's something of interest to more than just me. Also I 
am in contact with OSM folks, I know I am using free tile servers. How we run 
this as a public self funding service is one of the many things I need help 
with. It seems an obvious gimme for anyone selling bus tickets but it's not 
easy to get anyone to pick the phone up. I have resigned myself to having to 
build a production system in between doing not a lot.
