New Project In The Works: GPS Data Processing
GPS household surveys are all the rage these days - all the cool kids have one, and those that don't have one seem to think they are somehow not as cool. Of course, if everyone jumped off a bridge...
Anyway, I'm the lucky manager of the department that received the first GPS-only household survey. Since that time, three other agencies (that I can think of, at least) have these and each time there has been some improvements in the quality of the processing algorithms that I am trying to take advantage of. And everyone else gets the advantages, too, as I posted it on Github.
This currently uses sources presented at the Innovations in Travel Modeling Conference 2014 by Marcelo Oliveira at Westat. Westat wrote NCHRP 775 (08-89), and while the document had been completed since sometime before the conference, I was unable to sweet talk someone into emailing me an advance copy (it wasn't for the lack of trying). I did receive word that the document was to be released on Friday the 13th of June. I really hope the date is a coincidence.
The code on Github has a fairly detailed readme file (that shows up when you scroll down from the source listing, but it basically says that it's here, it's a work in progress, and I don't include data. My hope is that others can jump in and help and we can get a fairly nice system working. My other hope is that we can standardize processing a little and reduce the cost of these surveys.
This is my first use of Maven. I can't say I'm really using it now, so I have a lot to learn.
There are other side projects that may come out of this, but they will brought up in due time.
