Filling in Our Equity Map
Following up on our Transit Equity post yesterday, we've begun grabbing our Transit Scores. It's going to take about 10 days to fill them all in.
But meanwhile we'll show you the work in progress. This map has the census tracts that are complete so far, with the color representing the average Transit Score for the tract (hotter color = better transit). You can watch this fill out over the next few days!
I'm also going to try to generate more of a heat map display (which won't worry about the tract boundaries) - watch for that later...
You can also expect to see our data in tabular form soon as well.

This is a great project, Chris, and I'm glad to see that it appears you are including the suburbs as well as Portland. I look forward eagerly to your progress.

Chris, is the final version going to have an overlay of the TriMet district boundaries or will the extent of the census tracts roughly correspond to those boundaries?

Chris Smith Says:
Cora, the map will have all census tracts that contain a TriMet bus stop. If it seems useful I could add the TriMet boundary later (if I can find a shapefile for it).
There is one tract that reaches way towards Mt. Hood that I'm omitting because it was so big it killed my processes :-)

Added the service boundary. Thanks to TriMet for the KML file!

Hey Chris, any reason why you chose to use census tracks instead of blocks or block groups?

Actually writing a post about that for tomorrow :-) Fundamentally it's a question of what data sets I can find for the demographics.
Also, I'd probably have to collect even more data points if I went down to a smaller unit.

I don't suppose in doing this survey there is any interest in the current state of transit in this city?
Overcrowded, late as hell, a transit district about to experience labor unrest?
I guess that doesn't matter huh?
Never-mind.
