Looking to recreate this type of graph and was wondering if anyone was familar with a tool or application that might replicate it.

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.

 

Martin

Some googling led me to this blogpost: http://glowingpython.blogspot.com/2011/12/polar-charts-with-matplolib.html 

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

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
http://www.walkscore.com/transit-map.php is also very cool, showing travel time everywhere from a single location with a slider to change time of day. The archives of this group have a few threads about it, such as http://groups.google.com/group/transit-developers/browse_thread/thread/6806dce1f9d0cbee

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.
