Agenda

  • check-in

  • discussion of tickets

Minutes

Check-in:

  • everyone pleased with outcomes from last meeting

Discussion of #21

  • Brian has all tests passing on branch

  • Code is well-tested both from having been used for some time and has unit tests

  • fully handles GTFS spec

  • TODO: Brian will merge into trunk in the next two days

Discussion of #23

  • DECISION: agreed to jump to Java 1.6 as default

Discussion of a few different trip planer problems:

  • how do we want to handle different projections? Should just do everything in lat/lon internally and reproject in the output?

  • things to consider:

  • performance hit from distance calculations (can be improved by pre-calculating)

  • routing across large geographic distances

  • mapping form lat/lon to Vertex (#22) - can this be handled with an existing lib? (GeoTools, JTS, ?)

  • why are there non-spatial vertices?

  • Brandon: requires a long answer, will send out message to listserv. Short answer: encodes user state in the graph (tradeoff between storing in State, which leads to non-optimal trips from Dijkstra's algorithm, and storing in graph, which increases the size of the graph)

Lack of documentation

  • it'd be great to have both more documentation for the code and the trip planning problem in general

  • DECISION: start adding Javadoc comments

  • TODO: Nick will stub out documentation pages
