2012.05.24 Weekly Check in

• 13:31 <demory> hello everyone
• 13:31 <novalis_dt> hi
• 13:31 <novalis_dt> Do you know if Andrew will be in?
• 13:31 <novalis_dt> Because I broke a test and the CI server didn't mail me.
• 13:32 <demory> not sure; he was on earlier today wasn't he?
• 13:32 <novalis_dt> yep
• 13:32 <demory> in any case he didn't tell me he couldn't make it
• 13:33 <demory> why don't we go ahead and get started
• 13:33 <demory> hopefully Andrew will rejoin in a bit
• 13:34 <demory> my update: have been working on some enhancements for deployer, namely an improved upload interface. also just re-themed the front-end w/ the new OTP graphics: http://deployer.opentripplanner.org/
• 13:34 <novalis_dt> OK. I've been fixing misc bugs reported by e.g. johngouf and gboudreau.
• 13:34 <demory> currently working on the presentation for next week's OTP webinar w/ CUTR
• 13:34 <novalis_dt> I'm going to fix that failing test too
• 13:36 -!- githubbot [~[email protected]] has joined #opentripplanner
• 13:36 -githubbot:#opentripplanner- [OpenTripPlanner] novalis pushed 1 new commit to master: https://github.com/openplans/OpenTripPlanner/commit/023566164b5805483a2c44caf18c8688c1f19883
• 13:36 -githubbot:#opentripplanner- [OpenTripPlanner/master] return accidentally removed stuff which breaks test - novalis
• 13:36 -!- githubbot [~[email protected]] has left #opentripplanner
• 13:36 <novalis_dt> (done)
• 13:36 <novalis_dt> Anyone else?
• 13:36 <FrankP> working on our own graph builder / tester / deployer...automate the rebuild of a graph on updated gtfs files
• 13:37 <jcwong86> sorry just saw this. I'm here as well.
• 13:37 <demory> FrankP what are you using to automate that?
• 13:37 <demory> Hi James, thanks for joining
• 13:37 <FrankP> python scripts run via cron
• 13:38 <demory> FrankP you know the python code for our deployer is online at https://github.com/openplans/OTPSetup?
• 13:38 <demory> not sure if anything is re-usable there
• 13:38 <mele> Hi James! Grant and I are interns on the project too... for TriMet out in Oregon
• 13:38 <jcwong86> Hi @mele - nice to meet you guys
• 13:39 <jcwong86> not sure if we're still doing updates, but I'm playing around with data comparing Capital Bikeshare trips that were taken in Q1 this year with statistics from alternatively planned trips using OTP.
• 13:39 <FrankP> thank demory...saw that
• 13:39 <novalis_dt> jcwong86, cool. How are we doing?
• 13:40 <jcwong86> pretty good. we've got a couple different charts now that are helpful in understanding trips
• 13:40 <jcwong86> *understanding the kind of trips that bikeshare trips are replacing
• 13:41 <novalis_dt> Cool.
• 13:41 <jcwong86> it also helped validate travel times predicted by OTP for bikes. 50% of trips taken actually fall within 2 minutes of the bikeshare trip length
• 13:41 <jcwong86> 90% within 5 minutes
• 13:41 <novalis_dt> That is really nice performance, actually.
• 13:41 <novalis_dt> Are we consistently on one side or the other?
• 13:42 <novalis_dt> (i.e. too long or too short)
• 13:42 <jcwong86> *note that this is for fairly short trips, generally 25 min or shorter because of the nature of bikeshare trips
• 13:43 <jcwong86> its skewed towards predicting too quickly, but we won't conclude that side because people often do things other than rider directly from bike share station to station
• 13:43 <novalis_dt> Too bad we don't have GPS data for the bikeshare bikes
• 13:43 <jcwong86> there's terminal time to consider which changes the dynamics. just the fact that those percentages lie within the envelope is pretty good
• 13:43 <kpw> (we will for nyc!)
• 13:43 <novalis_dt> kpw, awesome!
• 13:44 <novalis_dt> Right, we actually do have a terminal time in the code
• 13:44 <jcwong86> @kpw really? is it just selective or will it transmit realtime?
• 13:44 <kpw> i think it's available after the trip
• 13:44 <jcwong86> *the bike times were compared with mode=BICYCLE, not rented bike
• 13:44 <kpw> don't know details, just keep hearing folks say the nyc bikes have gps
• 13:44 <novalis_dt> It's assumed to be one minute to pick up and 30 seconds to drop off, for what that's worth.
• 13:47 <demory> great work on the bike analysis
• 13:47 <demory> anything else?
• 13:47 <novalis_dt> Nothing here
• 13:48 <jcwong86> i'll wrap up the bike stuff and send out a doc with some findings and thoughts. it could probably use some help with any assumptions about OTP algorithms, but i'll pass that around later today or tomorrow.
• 13:49 <demory> great, thanks James
• 13:49 <demory> also, next week, that OTP webinar will likely run into our normal check-in time
• 13:49 <demory> here's ths info: http://transitgis.org/2012/05/18/transit-gis-clearinghouse-webinar-otp-and-its-deployment-at-trimet/
• 13:50 <demory> you all are welcome to listen in of course!
• 13:50 <novalis_dt> Cool!
• 13:51 <demory> maybe push the check-in back an hour, to 2:30 ET / 11:30 PT?
• 13:51 <novalis_dt> Works for me
• 13:51 <demory> ok. I'll send a reminder by email
• 13:52 <demory> thanks everyone!
• 13:52 <FrankP> sounds good -- 11:30am ... good luck next week
• 13:54 <demory> thanks Frank!
• 13:57 -!- abyrd_ [~[email protected]] has joined #opentripplanner
• 13:57 -!- abyrd [~[email protected]] has joined #opentripplanner
• 13:58 -!- abyrd [~[email protected]] has quit [Client Quit]
• 14:01 <demory> hey abyrd_, we just wrapped up the check-in but if you have anything to report I'll include it in the transcript
• 14:01 <demory> also I think novalis_dt had a question for you about the CI server
• 14:01 <abyrd_> hi demory, got stuck in a train.
• 14:02 <novalis_dt> abyrd_, yeah, I broke the tests recently and didn't get an email
• 14:02 <abyrd_> I'm just working on realtime stoptime updates and batch queries
• 14:03 <abyrd_> novalis_dt, yes I saw that too. It is configured to send messages to anyone who breaks the build but is not doing so. Will check if this is a known issue, and if there is an upgrade with a bugfix.
• 14:03 <novalis_dt> Thanks.
