Back in 2012, I worked with Auckland Transport to design a completely new design for the city’s transit system. (Auckland has a single city government covering the whole urban region, so you could also call this a regional plan.)
The old design — if it could be a design at all — had been the result of private operating companies designing their own routes to their own advantage, which led to enormous numbers of express buses into the Auckland city centre (where they created major bus congestion) but poor services for getting around locally or crosstown. It was also just impossibly complicated …
A small piece of the network, in the Green Bay area, was implemented last year, and achieved a 20% ridership increase (on no increase in service quantity) in the first year. Now, the first really big piece has been rolled out across southern Auckland. This area, formerly the City of Manukau, is relatively low-income, ethnically diverse, and features fragmentary, shredded street patterns that are a huge challenge to network designers.
A fragment of the old network is above. Virtually none of it, including the train line, was frequent. The overlapping lines with uncountable 3-digit-route numbers show local routes tangled up in express routes going all the way into the CBD far to the north, competing with the rail line.
Here’s the same slice of the new network (beautiful full map here):
Why the huge reduction in complexity? Virtually all express buses to the CBD were replaced by buses connecting to the main rail line, which is now frequent. Local lines were organized so that they form a logical network feeding into local hubs as well as to major rail stations. Note that not all rail stations are bus hubs; the network concentrates only on certain rail stations so that buses connect with each other as well as with the trains, and so that consolidated station facilities can be built at these locations. The biggest new hub, Otahuhu at the north end of South Auckland, has a huge number of buses feeding it, and got a shiny new bus-rail station for the new network’s opening day.
As always, there will be hiccups in the implementation process, as people adjust. But it’s great to see this plan, first sketched four years ago, on the street at last.
