Auckland Plan Transport Network: 2040

Key Local road and public transport projects

State highway projects

Auckland rail patronage growth- 22% a year

6

Public transport users - changing • NZTA research says the extent to which Generation Y has embraced public transport (PT) and would use it more if it was improved is underestimated • Generation Y (1979-1999) is shunning car ownership in favour of PT - their PT use has been increasing since the turn of the century unlike other age groups. Driver licences also less common.

• Generation Zero, a non partisan youth-led organisation that arose from the Copenhagen youth summit has the central purpose of providing solutions for cutting carbon pollution through smarter transport • Suits on trains a norm with annual rail patronage growing 22% • Chinese and Hindi now 2nd and 4th most spoken languages in Auckland

Facts and figures • • • • • • •

CRL challenges • • • • • • • •

70m to climb in 3.4 km of railway Major utilities to relocate Cut and cover construction within the CBD Shafts at Karangahape Rd Maintaining rail operations at Britomart and Mt Eden Underpinning CPO at Britomart Integration with other major projects Minimising waste

20

Engineering challenges • Disciplines Interface - civil, architecture, building services railway systems • Geotech – below sea level and reclaimed land in city with basalt at Mt Eden • Underpinning the CPO • CBD environment- stakeholders, businesses, residents, workers • Interface with other developments- Precinct, NDG, Mansons, Conrad Properties, Skycity Convention Centre etc

21

Design challenges • Britomart - a modern station interchange within a heritage building • Consistency of the underground railway but expressing the individual identities of the stations it passes through • Integrating manawhenua narratives into the success of the design • Planning for future growth – sizing everything to provide for significant uptake

22

Sustainability challenges • Piloting an IS rating tool on the enabling works

• Targeting an “excellent” rating • Working with Manawhenua to embed cultural values in the rating tool • Striving for zero waste to landfill during construction • Minimise use of materials energy and water

Property challenge • • • • • •

Vast majority of the 68 surface properties needed have been acquired Most in main construction site adjacent to Mt Eden Station About $90m spent on property Sub surface negotiations start next year CRL portfolio has about 40,000 sqm of property - most commercial Less than 5% vacancy

27

Traffic challenge

Congestion conditions.

Expected congestion – additional bus priority lanes as mitigation.

PT Objectives: - Retain levels of service.

- Allow for customer growth.

- Target mode shift to PT.

Buses need to move out of lower CBD for CRL –51% of trips affected.

Stage 1 complete Stage 2 in design for 17/4/16

Traffic assessment process Historic data on 10 routes (travel time – mins) Traffic modelling of works with combined “other projects” Implement Review actual travel times against modelled effects

Further mitigation (as required)

Additional bus lane network

Stage 1- Oct 2015 • New bus lanes on Halsey, Fanshawe, Wellesley, Victoria and Hobson Streets and Mayoral Drive.

• Total of 1.2km of lanes

Stage 2- April 2016 • New bus lanes on Queen and Customs Streets.

• Total of 1 km of lanes

Questions?

Transport - Conclusions • There is an established way of approach transport appraisal based on straight line growth forecasts and values of time with fixed population and employment patterns, but it is not clear that it reflects what actually happens • In reality transport drives land use patterns just as much as land use drives transport demand
