What’s the Right Scale for Our Equity Analysis?

The first pass of scoring is complete, sort of. The map of all the selected tracts is below, and it’s apparent that the strategy of selecting just those tracts that have bus stops is insufficient, there are a number of census tracts inside the TriMet service boundary that have no bus stops. So I need to do a bit more work on that.

But I’m more interested in the fact that the map is pretty “flat”. There aren’t a lot of variations from tract to tract (there is of course the expected increase in scores as you move toward the center of the region). I’m wondering if a census tract is too large a unit, if it “evens out” differences in service levels across too big a geographic area.

One commenter suggested using census block groups, the next smaller unit (about 3 or 4 per tract). I’m going to look at that because the ACS data will have some information at that level.

So look for another map, hopefully by next week. I’d welcome other thoughts or suggestions. And I’ll get a tabular data set of points up once I’ve filled in the holes in my map.

Pedestrian Advisory Committee Seeks New Members

From the City of Portland:

Pedestrian Advisory Committee seeks new members

The Portland Bureau of Transportation announced that it is seeking new members for the Pedestrian Advisory Committee (PAC). The PAC advises the City of Portland – particularly the Bureau of Transportation – on matters that encourage and enhance walking as a means of transportation, recreation, wellness and environmental enhancement. The PAC is a 9- to 13-person committee that represents a cross-section of Portlanders, including walking and mobility advocates, neighborhood activists, environmental design professionals and citizens-at-large.

The PAC meets the third Tuesday evening each month. Members are appointed to a 4-year term. PAC member activities include, but are not limited to, reviewing and making recommendations on:

* planning documents affecting pedestrians
* pedestrian projects
* projects with pedestrian facilities
* funding priorities for pedestrian-related projects
* activities of other jurisdictions that affect pedestrians in Portland
* maintaining and periodically updating the Portland Pedestrian Design Guide and Pedestrian Master Plan

Qualified individuals must:

* be a resident of or own a business in the City of Portland
* have an interest in promoting the use of walking for transportation and recreation
* commit to attend monthly meetings and participate in the work of the committee
