This is a great initiative, I remember sometime last year I wanted to create schematic transit map for a few of the services in my city, only to realise that there might not be software to automate the process. Would have been great if I took out some paper and Inkscape to try it out, but I moved on to more important things. Definitely will be following the project, maybe I can create a GTFS bridge with my dataset and try out the project :)

Thanks for the feedback! Project is definitely under daily development and subject to changes but it should be ready for reuse soon.

We use OpenTripPlanner for translating GTFS in a format to use with this. What type of bridge did you have in mind? What city/services were you looking at?

In the demo (http://conveyal.com/transitive.js/) the blue and orange line unnecessarily overlaps with each other near Rosslyn, and the path from Start to End through Farragut North Area is unnecessarily overlapping with blue and orange line. Any particular reason?

I'm in South Africa, developing a public transit planner for Johannesburg and surrounds (you can check it out at https://rwt.to [search for "Naledi, Soweto" to "Hatfield Square, Pretoria" as an example], also obviously still under development).

I opted not to use GTFS as it didn't meet my needs with regards to many things, for example I built a pricing engine/calculator which calculates prices dynamically based on a set of rules, and as a result for train services that are priced based on track distance, I needed to draw the tracks accurate to a few meters per km, so that I can extract the pricing information from there.

When I have time in the near future, I want to write a Node.js script that converts the data that I have to GTFS, fairly trivial but not a priority at this point :)

Yes, that's a known issue; the crossing minimization piece still needs some refinement. Hope to have it fixed within the next week.
