I'm a software developer at a freight logistics firm. I graduated with B.S. Computer Science from Arkansas Tech University. I grew up in western Honshu, Japan.

I taught myself HTML/CSS when I was in middle school. I was fascinated by the design aspect (graphics/typography/layout) of creating websites. In high school I taught myself some C++ and Javascript. In college I studied programming, doing a fair amount of coding in C++ with a little of bit of Java and assembly as well (and became enamored of vi).

Now days I code for a living, developing client-server apps in C# (and previously VB.Net), writing units tests with NUnit & RhinoMocks, and interacting with DB2 and the occasional mainframe COBOL program, with WinForms on the front end. I do some Python and PowerShell scripting on the side to make my life easier.

I am passionate about the field of public transit and transportation networks in general. I hope to develop my craft and apply it to solving interesting problems in those areas.

Thanks! Great analysis :)

Ah, I understand now. I only had one semester (working through ArcGIS tutorials) of GIS in college, so my knowledge is rather lacking. Took me moment to catch on ;) - question re-edited.

comment Finding intersection density for weighted lines connecting points across the continental USA
Yea, I see now that the intersection step is really unnecessary. It seems like simply buffering the zip-code centroids (maybe ~250 miles?) and summing the passenger volumes on the lines contained would provide a decent result and save on computation costs.

@Jzl5325: Yup, I meant a strict sphere and not ellipsoid, edited the question to provide a bit more context too.

Good point on interpolating. In face I think I can probably skip the line intersections step (I could just see what lines intersect the buffer zip-code centroid). I wondering if using Shapely is the way to go... maybe I just need to project all my lat/long coordinates into x,y miles on a Albers Equal Area projection and go.

comment What is the highest resolution of population density data that I can obtain for USA freely?
+1 for merged files... having to put those two files back together can be such an (unnecessary) pain!
