Busable Wellington

In response to a reader request, here are the same bus service maps as for Auckland. Again, click for big PDF files so you can zoom in.  I think these include non-bus transit, but I’m not completely sure.

Hours per day with at least six transit trips within 500m

Hours per day with at least 12 transit trips within 500m

In the Wellington region it seems that people who have any bus service have a useful amount.

The region as a whole has a smaller proportion of people with good public transport than Auckland region (7% in the top category, 60% in the bottom), but if we restrict to Wellington City there are 17% in the top category, 26% in the next, and only 30% in the lowest.

 

[Update: Here's a version with a 1km distance instead of 500m]

    it seems to only be buses, though it’s hard to tell.

    Question: if it’s a count of transit services within 500m, and your spatial unit is the meshblock, how do you determine distance? From the centre of the meshblock? Any edge? A spatial intersection? I always make that clear when doing these types of analyses, given that a meshblock can be more than 500m.

    Research also shows people are willing to walk further than 500m to reliable, high capacity and frequent transit, such as trains. All the park and rides at Wellington region train stations are at capacity, too. Wellington has a higher transit mode share than Auckland

      It’s the ‘label point’ of the first polygon in the shapefile for the meshblock. I did say in the Auckland post. This seems to be reasonably close to the centroid in the few examples I looked at.

      In principle, extending from 500m to 1000m could reveal completely new well-served areas, but I’d expect it mostly would just expand the fringes. Another problem in both cities is with straight-line distances: in Wellington, a lot of the 500m around the bus stops at VUW is far enough away vertically to be a problem, and in Auckland it isn’t sensible to walk over Mt Eden if it happens to be between you and a bus.

    Some roads aren’t going to get a useful amount because they just aren’t made for buses
