I'm sure R has routines/packages to plot this kind of graph/plot. You
could use Python to generate the summary variables from the GTFS.

So you want to visualize transit services between a fixed number of points?
For example: angle=time of day, radius=travel distance, color=average speed
to get to a selection of points at that distance
[link] is also very cool, showing travel
time everywhere from a single location with a slider to change time of day.

Some googling led me to this blogpost:

Seems that library will let you do that, but not sure if that's what you're
after or not.

Hello all,

I don't know if anyone has seen this type of graph but I would like to implement it for project to provide a snapshot of transit access to employment by travel time and time of day.

Any insights would be greatly appreciated. Our primary coding environment is python.

Thank you all in advance.

I think we did meet at TransportationCamp. It's good to hear from you
on the list.

I've never heard of a tool that supports any of these three features.
However, the project I work on, OpenTripPlanner, supports pluggable fare
models, which would easily handle distance-based fares. I expect I

Hi All

I think I may have met some of you at Open Plans’ Transportation Camp
in Washington back in January, and I may have mentioned a World Bank
funded project to create a public transport database and GTFS feed for
Metro Manila. Since then we have been working on behalf of the
Philippines Department of Transport and Communications, and a number

The Spatialite extension to SQLite can support routing queries,
(provided you generate a routing network/graph from your roads/routes).

You'd probably have to create a real spatial/geometry table first from
'shapes.txt',
then build the routing network over that, you couldn't do it without

Hello
if you have any idea that can help me i would be gratful
i want to create a web service for the location of buses by GPS,
(this web service will communicate with my android app)
any user can at any time consult this application and know the exact
location of the bus so he can know the estimated time for the bus

All (cross-posted to transit-developers and siri-developers),

We are contemplating some API improvement to the Bus Time API ([link]), and there's an issue with a non-obviously-right answer that we'd like some feedback on if possible. Unfortunately, it's hard to ask the question without setting the stage a little (which may ultimately mean that it just doesn't matter). The question surrounds what to include in stop-centric API calls about a bus that has not yet started the trip on which it will serve the stop in question.

I wasn't able to find an example of the same route names being used.

Here are a few examples of multiple operators serving the same location in Google Maps:

2 agencies: [link]

3 agencies: [link]

True. Seeing as how more and more agencies are providing GTFS data feeds,
there will come a point where you need a way to distinguish services
provided by these operators. Both operators could have the same route
number but the only way to tell is the headsign or in some cases, the
colors used in the routes.txt file.

Posted: May 7, 2012, 10:29 pm

I agree that it's useful to separate services by the brand or operator.

Also, I actually do like the idea of using icons in some ways. I was just
sharing a potential issue there.

MBTA's T logo is used on their subway and rail stations. I think they had
some sort of thing set up to where Google could put their logo within the
stop details. Even if it isn't an agency logo, maybe some sort of marker or
highlighting could be used to distinguish multiple operators at the same

Posted: May 7, 2012, 10:13 pm

Some GTFS license agreements limit how the the agency logo may be used in 3rd party services. The agencies reserve their logo as a way of marking agency-provided/official information.

I believe that both TriMet and BART have included this in their license agreements. I have not looked at other license agreements.
