In the demo (<a href="http://conveyal.com/transitive.js/" rel="nofollow">http://conveyal.com/transitive.js/</a>) 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?
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 :)
