Around two weeks ago AT gave a presentation to the Council’s Infrastructure committee which contained a lot of very interesting information about some of the major projects they’re working on. I also heard a segment of the presentation at a talk last week. I won’t cover everything in the presentation as much of the charts and maps are ones we’ve seen before that I found interesting.
The presentation starts by looking at Auckland’s expected population growth in comparison to the growth happening in the rest of NZ using some charts most will probably be familiar with. Just in case you aren’t they highlight that using the medium growth projections out to 2043 that more than half of all population growth will be in Auckland and that growth alone will equal be greater than the current population of Christchurch and its expected growth. What was interesting though was the chart below showing how Auckland has grown compared to the previous population projections and as you can see the projections keep being revised upwards. The 1996 projection estimated Auckland would hit 2 million people in 2063 but the 2013 one suggests it will now be 2033.
As mentioned the growth is comparable to the expected population in Christchurch and the image below shows the land area of all of the greenfield growth (blue) and Special Housing Areas (Orange) from across the region combined into one Christchurch sized mass – I’ve also seen a version comparing it to Hamilton with roughly a Hamilton sized growth occurring in the South, about a 2/3rds Hamilton in the North West and half a Hamilton in the North.
On the topic of growth this chart highlights just how much is expected to occur in the city centre – which is the CBD and fringe suburbs such as Grafton, Newmarket Parnell, Ponsonby etc. – compared to other parts of Auckland. I’m not quite sure where the boundaries for the other areas are but it’s also interesting to see the second biggest expected employment growth area is in the North West.
Moving on to some of the more interesting aspects of the presentation, there is a series of maps showing how the Rapid Transit Network will develop over the next 30 years. Now what does that presentation format remind you of? It’s great that AT are now starting to present the information this way as personally I think it makes it much easier for the general public to understand what’s proposed for their city.
One aspect you will notice is the access to the Airport. The map shows both heavy and light rail options as it has yet to be decided which one will be built. Accompanying the presentation was an animated video that showed the options in much more detail including what they would look like between Onehunga and Kirkbride Rd. This hasn’t yet been published so I’ve asked AT when that will happen as it was very interesting. I’ll discuss a little more about this later in the post. Also the more I look at it the more I think it seems natural for light rail to be extended over to the North Shore where it can then spread out again to provide greater coverage.
On light rail the presentation moved on to AT’s proposal for it on the isthmus. A lot of the justification for it is to reduce the number of buses in the city centre as some corridors like Wellesley St will have over 180 per hour in the peak direction based on current plans. We’ve shown these maps before but they’re worth repeating.s
And with LRT in place bus numbers reduce dramatically. One thing I am aware of is that the map below is not be entirely correct as I know the board have decided not to send LRT down to Quay St, instead it will stay on Customs St (and presumably travel down Fanshawe St).
It still leaves Wellesley St as a very busy bus corridor but allows more buses from other parts of the city not served by heavy or light rail. Thee impact of not building Light Rail is highlighted in this map showing that bus congestion in the city slows buses down reducing the number of people within a 45 minute trip of the city centre. Interestingly some of the worst affected areas are the North Shore which again suggests it’s probably worth looking at something like LRT to the shore to reduce the reliance on buses.
Note: the map shows that many of the ferry routes don’t seem to be counted. My guess is this the map is based on a combination of walking time and average wait time for a service plus the travel time to a set point in the city centre.
The next map shows a great representation of how people will access the city centre by mode in the future if current plans are built. As you can see the existing rail network plus the CRL serve the South, East and West through connections with feeder buses. The central Isthmus is served by light rail, many of the coastal communities are served by ferry and the rest of the city by bus.
As mentioned earlier, there was some information on the options for rail to the airport. The three images below show how far you would get from the airport on public transport now, with heavy rail and with light rail. As a basis it seems to assume that the isthmus light rail routes have been completed and like the accessibility maps will likely be based on some average wait time and possibly only using normal PT options so no Skybus.
With Heavy Rail you can definitely get much further
And the light rail version which connect to the isthmus routes via a connection from Onehunga to Dominion Rd on a route alongside SH20.
There are some odd things with these maps, for example as I understand it the idea with the light rail option is only the Dominion Rd route would go to the airport which means a transfer for those using the other lines. Why then can you get further up Manukau Rd on LRT when Heavy Rail is much faster to get to Onehunga.
There is more info in there in the interests of time and space I might leave some aspects to another post.
All up a very interesting presentation.
