A New Public Transport Approach

FIT stands for Fair, Intelligent Transport. We are a group of Wellingtonians with professional expertise, who want to see a change from the culture where the private motor vehicle dominates other transport modes.

Light rail costs have fallen in recent years, and last year the International Railway Journal quoted €25-30';m;' per kilometre for a typical line in France: NZ $42-51';m;'/km. Now Besan�on, France has opened a new line for €17.5';m;'/km: $30';m;'/km. Using these figures as a guide, we consider the costs set out in Tab(indicativeCosts) are reasonable. We have assumed:

In the southern CBD we propose either a Cuba St route or a faster route via Taranaki St (options 2a and 2b); Wallace St with access to Wellington High School and Massey University; then on to Newtown via John and Riddiford Streets via Wellington Hospital. This route, running west of the Basin Reserve, would be better aligned with the light rail [[#principles |design principles]], with more opportunities at the Hospital and through Newtown. The curves in the John St area mean slightly reduce operating speeds.

South of Wellington Hospital we propose a route to Kilbirnie by either Wellington Zoo or Constable Street and Crawford Road (options 3a & 3b). In either case the proposed Kilbirnie interchange is on commercial land at Coutts Street, opposite Bay Road. In this case the options have important cost effects, because of tunnels: option 3a will cost an additional $212 million. This area is discussed further in Sec(costs).

!!!Design principles

In the southern CBD we propose either a Cuba St route or a faster route via Taranaki St (options 2a and 2b); Wallace St with access to Wellington High School and Massey University; then on to Newtown via John and Riddiford Streets via Wellington Hospital. This route, running east of the Basin Reserve, would be better aligned with the light rail design principles, with more opportunities at the Hospital and through Newtown.

In the southern CBD we propose either a Cuba St route or a faster route via Taranaki St (options 2a and 2b); Wallace St with access to Wellington High School and Massey University; then on to Newtown via John and Riddiford Streets via Wellington Hospital. This route, running east of the Basin Reserve, would be better aligned with the features identified by planners for light rail systems, with more opportunities at the Hospital and through Newtown.

These needs will have to be "rationed", to manage both a peak-hour maximum of 60 buses an hour on all routes--for congestion-free running--and the cost of running buses and light rail in competition. Most or all other bus services would terminate at one of the interchanges. (split into bullets?)

We believe that the spine study identifies the wrong route for rapid transit from the {CBD|Central Business District} to Kilbirnie. We also believe that alternative routes exist which avoid the choke point at the Basin Reserve, and that light rail would provide a far superior transit system for comparable cost to implementing BRT as currently proposed. The body of this report presents evidence to support this view.

Peak capacity for light rail running on-street is about 40 trams an hour: lower than for buses because there is rarely space to berth two trams. Light rail capacity depends on high-capacity vehicles, perhaps carrying around 300-400 people in Wellington. A few buses sharing a light rail route will disrupt route capacity, but excluding all buses from the central city may not be possible: light rail needs a second route for the remaining buses.

Of course nobody wants transfers if they can avoid them. But no information was given on how the inconvenience  can be minimized or mitigated when combined with a superior and faster mode like light rail. Respondents will have in their minds the painfully slow and erratic transfers experienced in Wellington.

* Speed throughout the route, with an indicative travel time to the Airport of 20-25 minutes.

* Very smooth ride. A common sight is standing passengers when there are plenty of seats.

Principal considerations in deciding between options will be vehicle speed, walking distance and passenger numbers walking. Further investigation is needed to determine whether a dedicated light rail route on Lambton Quay south of Panama Street is feasible, as this would require removing buses from this part of Lambton Quay. Such a route would then follow Willeston, Victoria and Wakefield streets to Cuba St (option 2a) or Willeston St to Jervois Quay and Taranaki St (option 2b). We have identified this as a desirable route, but do not have enough information to determine its technical feasibility and estimate the cost.

In the southern CBD we propose either a Cuba St route or the straight and therefore quicker route via Taranaki St (options 2a and 2b), moving on to Wallace St to allow access to Wellington High School and Massey University; then on to Newtown via John and Riddiford Streets via Wellington Hospital. This route, running east of the Basin Reserve, would be better aligned with the features identified by French planners, with more opportunities at the Hospital and through Newtown.

South of Constable Street we propose a route to Kilbirnie by either Wellington Zoo or Constable Street and Crawford Road (options 3a & 3b). In either case the proposed interchange is on commercial land at Coutts Street, opposite Bay Road. In this case the options have important cost effects, because of tunnels: option 3a will cost an additional $212 million. This area is discussed further in Sec(costs).

The main advantage of a Constable Street route is cost because it bypasses the longest tunnel. The main disadvantage is the loss of light rail patronage in the denser Newtown area.

For option 3a we propose a single-track tunnel to Kilbirnie. Single track is justified because the heaviest light rail traffic will be in the city centre and a reduced service can be justified beyond Wellington Hospital. Tunnel capacity should be at least 12 trams an hour each way, or say 3500 passengers an hour. This is an initial estimate and can probably be increased after timetable modelling. A second tunnel will be needed if capacity is ever reached.

* The lower end of Crawford Road, which is less than 11 metres wide. Childers Terrace would be a tempting option but a mistake: trams would run above the main interceptor sewer.

* Full service on short routes incompatible with transfers, such as Brooklyn and Kingston; Mt Victoria; Aro Street or Kelburn; or busy corridors requiring two transfers.

These needs will have to be "rationed", to manage both a peak-hour maximum of 60 buses an hour on all routes--for congestion-free running--and the cost of running buses and light rail in competition. Most or all other bus services would terminate at one of the interchanges.

* a further 20% for design and contingency

We acknowledge there are challenges in the Constable St option, but are confident that the engineers could find workable solutions. Clearly, the cost saving would be considerable--enough to fund over 4km of light rail construction, e.g. a line to Island Bay. A detailed study will be needed to determine which option is best value for money.

We consider there are grave deficiencies in the proposals for {BRT|Bus Rapid Transit} and the spine study on which it is based. In particular, the underlying assumptions adopted for light rail in the spine study inevitably resulted in this being a high-cost, low-benefit option. We believe these assumptions are no longer appropriate.

This report presents two options for light rail through central Wellington to Kilbirnie and on to the Airport, together with a supporting bus network. We acknowledge that there are other route options for light rail than those presented here; in particular, we recognise the desirability of operating along the full length of the golden mile. A route via the Basin Reserve would also be feasible.

Of course nobody wants transfers if they can avoid them. But no information was given on how the inconvenience  can be minimized or mitigated when combined with a superior and faster mode like light rail. Respondents will have in their minds the painfully slow and erratic transfers that they experience with current bus transport in Wellington.

High capacity also demands frequent buses, which are too easily slowed by delays at traffic signals or bus stops. BRT needs a high priority at traffic signals (or a flyover) and overtaking lanes at stops. BRT can be space-intensive; for example, BRT stops in Brisbane are twice the width of Manners Mall.

High capacity also demands frequent buses, which are too easily slowed by delays at traffic signals or bus stops. BRT needs a high priority at traffic signals (or a flyover) and overtaking lanes at stops.

BRT stops in Brisbane are twice the width of Manners Mall. The capacity of the Brisbane busway is given as [[nearly 300 bus/hr -> https://en.wikipedia.org/wiki/Busways_in_Brisbane]], compared with only about 40 trams an hour for light rail running on-street: lower than for buses because there is rarely space to berth two trams. Light rail capacity depends on high-capacity vehicles, perhaps carrying around 300-400 people in Wellington. A few buses sharing a light rail route will disrupt route capacity, but excluding all buses from the central city may not be possible: light rail needs a second route for the remaining buses.

[tangled sentence: how about]
At the city end, we propose two alternatives:
--either a dedicated right of way on the west (Terrace) side of Lambton Quay, crossing to Jervois Quay at Willeston Street (if practical) or Panama Street
--or a waterfront route along the east side of Customhouse Quay. See Fig(innerCityMap), options 1a and 1b.
Principal considerations in deciding between options will be vehicle speed, walking distance and passenger numbers walking. Further investigation is needed to determine whether a dedicated light rail route on Lambton Quay south of Panama Street is feasible, as this would require removing buses from this part of Lambton Quay. Such a route would then follow Willeston, Victoria and Wakefield streets to Cuba St (option 2a) or Willeston St to Jervois Quay and Taranaki St (option 2b).

We believe that the spine study identifies the wrong route for rapid transit from the {CBD|Central Business District} to Kilbirnie. We also believe that alternative routes exist which avoid the choke point at the Basin Reserve and that light rail would provide a far superior transit system for comparable cost to implementing BRT as currently proposed. The body of this report presents evidence to support this view.

BRT for Wellington will not be rapid and will not meet the minimum [[internationally adopted standard -> https://www.itdp.org/library/standards-and-guides/the-bus-rapid-transit-standard/]] for a bus system to qualify as BRT. We expect that light rail in Wellington will be cheaper than the street-widening and amenity costs of BRT.

The identified route does not run by the Basin Reserve, although it is within the area defined in the {N2A|Ngauranga to Airport} study. Recent events suggest difficulties in finding a reserved route, and multi-segment trains can be difficult on large, multi-lane roundabouts. This corridor is more suited to buses, with no particular reason to run a high-capacity route that way.

At the city end, we propose either a dedicated right of way on the west (Terrace) side of Lambton Quay, crossing to Jervois Quay at either Willeston Street (if practical) or Panama Street, or a waterfront route along the east side of Customhouse Quay.

Capacity should be at least 12 trams an hour each way, or say 3500 passengers an hour. This is an initial estimate and can probably be increased after timetable modelling. A second tunnel will be needed if capacity is ever reached.

Either option will require a tunnel beneath the airport runway. A single-track tunnel will be satisfactory for option 3b, but option 3a may need a two-way layout. This can be checked using timetable modelling but must be assumed at this stage.

* Managing eastbound traffic reaching Constable Street, to control queue-lengths at traffic signals and minimize peak-hour tram delays.

Most or all other bus services would terminate at one of the interchanges.

The first light rail line in a new city typically takes ten years from the go-ahead: the existing bus route will need alterations to boost capacity until light rail can take over.

Light rail costs have fallen in recent years, and last year the International Railway Journal quoted €25-30';m;' per kilometre for a typical line in France: NZ $42-51';m;'/km. Now Besançon, France has opened a new line for €17.5';m;'/km: $30';m;'/km.

We suggest the costs set out in Tab(indicativeCosts) are reasonable, based on an all-up cost of $40 million per route kilometre,  including depot and vehicles but excluding tunnels. We have allowed allowed a further 20% for design and contingency. We assume all interchanges can be built within this all-up cost, bearing in mind the value of residential development around a main interchange. Note that there are some rounding errors; all costs exclude GST.

!!Bus public transport

BRT is an effective solution in many cities. The problems in Wellington are narrow and winding streets and the need for large cumbersome buses to gain capacity: these pose dangers for other road-users.  High capacity also demands frequent buses, which are too easily slowed by delays at traffic signals or bus stops. BRT needs a high priority at traffic signals (or a flyover) and overtaking lanes at stops.

BRT for Wellington will not be rapid and will not meet the minimum [[internationally adopted standard -> https://www.itdp.org/library/standards-and-guides/the-bus-rapid-transit-standard/]] for a bus system to qualify as BRT.

We note that BRT stops in Brisbane are twice the width of Manners Mall, and we expect that light rail in Wellington will be cheaper than the street-widening and amenity costs of BRT.

Transfers are a successful and uncontroversial feature of most overseas public transport systems. The claimed unpopularity of transfers in Wellington is based on unsatisfactory questions posed in the spine study, without balancing information. This approach unnecessarily biased respondents against transfers, e.g.

Of course nobody wants transfers if they can avoid them. But no information was given on how transfers can be made least inconvenient when combined with a superior and faster mode like light rail. Respondents will have in their minds the painfully slow and erratic transfers that they experience with current bus transport in Wellington.

And, of course, everybody wants faster, cheaper and much more reliable trips anywhere-to-anywhere, but can be put off by biased questions.

FIT stands for Fair, Intelligent Transport. We are a group of concerned Wellingtonians with professional expertise, who want to see a change in the culture where the private motor vehicle dominates over other transport modes. We want to see a city designed around the needs of people, not cars. Our vision for Wellington is a modern, vibrant city which includes:

* A city that has reliable, low-cost, fast and convenient public transport, that takes people to where they want; and

* A city where walking, cycling and electric public transport are actively promoted to reduce transport costs, improve health by physical exercise and reducing pollution and climate change effects.

We have reviewed the business plan for the development of public transport in Wellington and we consider there are grave deficiencies in the proposals for {BRT|Bus Rapid Transit} and the spine study on which it is based. We strongly believe that the spine study identifies the wrong route for rapid transit from the {CBD|Central Business District} to Kilbirnie. We also believe that alternative routes exist that avoid the choke point at the Basin Reserve and that light rail would provide a far superior transit system for comparable cost of the implementation of BRT as currently proposed.

In this report we present two options for light rail through central Wellington to Kilbirnie and on to the airport together with a supporting bus network. We acknowledge that there maybe other route options for light rail than those presented here and in particular the desirability of operating along the full length of the golden mile.

Planned, near-seamless transfers at quality interchanges are necessary for light rail in Wellington as they are everywhere else in the world. Transfers will dramatically reduce bus-kilometres, mainly on the golden mile, allowing more and better services on remaining routes. Good interchange and timetable design minimizes transfer times (generally 2-5 minutes),[^2009 Opus survey and 2011 Bus Review^] making many trips faster overall.

Transfers are a successful and uncontroversial feature of most overseas public transport systems. The claimed unpopularity of transfers in Wellington is based on unsatisfactory questions posed in the spine study without balancing information. This approach unnecessarily biased respondents against transfers, e.g.

We have identified feasible and affordable options for light rail and a supporting bus network. We are confident that we have identified workable options, combining buses and light rail, but have not identified a best or preferred option. We propose buses and light rail on fully separated routes, both on or close to the golden mile.

* Excellent timekeeping at all times of day, making consistent timetables and timed transfers practical.

At the city end, we propose either a dedicated right of way on the west (Terrace) side of Lambton Quay, crossing to Jervois Quay at either Willeston Street (if practical) or Panama Street, or a waterfront route along the east side of Customhouse Quay. See Fig(innerCityMap), options 1a and 1b. Principal considerations in deciding which option will be vehicle speed, walking distance and passenger numbers walking. Further investigation is needed to determine whether a dedicated light rail route on Lambton Quay south of Panama Street is feasible, as this would require removing buses from this part of Lambton Quay.

In the southern CBD we propose either a Cuba St route or the straight and therefore quick route via Taranaki St (options 2a and 2b), moving on to Wallace St to allow access to Wellington High School and Massey University; then on to Newtown via John and Riddiford Streets via Wellington Hospital. A route running east of the Basin Reserve would be better aligned with the features identified by French planners, with more opportunities at the Hospital and through Newtown.

South of Constable Street we propose a route to Kilbirnie by either Wellington Zoo or Constable Street and Crawford Road (options 3a & 3b). In either case the proposed interchange is on commercial land at Coutts Street, opposite Bay Road. In this case the options have important cost effects, because of tunnels: option 3a will cost an additional $212 million. This area is discussed further in Sec(costs).

The main advantage to a Constable Street route is cost, because it lowers the cost of tunnels. The main disadvantage is the loss of light rail traffic in the denser Newtown area.

* The lower end of Crawford Road, which is less than 11 metres wide. Childers Terrace would be tempting but a mistake: trams would run above the main interceptor sewer.

* Possibly a full service on longer routes such as Karori. In this case the route should probably pass through the Railway Station interchange, if not terminate there.

We suggest the costs set out in Tab(indicativeCosts) are reasonable, based on an all-up cost of $40 million per route kilometre,  including depot and vehicles but excluding tunnels. We have assumed that all interchanges can be built within this all-up cost, bearing in mind the value of residential development around a main interchange. Note that there are some rounding errors; all costs exclude GST.

At this stage tunnelling costs are based on four assumptions:

* Reaching capacity in the Mt Albert tunnel is sufficiently far into the future to justify a single-track tunnel.

We present options for buses and light rail in Wellington. Light rail runs from the Railway Station to Wellington Airport, taking over the busiest corridor, and the remaining buses in the central city are reduced to manageable numbers.

(:typeset-page headingcolor=ForestGreen fontset=freebe colorlinks=on title="A New Public Transport Approach for Wellington" subtitle="Options and Indicative Costs" autonumber=1 toc=2col imagesize=sidecaps colophon=off parasep=space :)

We identify a number of deficiencies in the business plan for {BRT|Bus Rapid Transit} and the spine study on which it is based: the proposed route bypasses where people live, and involves expensive tunnelling through Mt Victoria, with destruction of town belt and housing eastwards. We provide alternative routes which bypass the choke point at the Basin Reserve.

We believe light rail is superior to large buses for most transport along the spine, given Wellington's geography. Our calculations project comparable set-up costs and less expense to run. Light rail also brings productivity gains because it is faster.

As a result of our research, we present two workable routes, although we acknowledge that other routes are also possible. We suggest that the Golden Mile should be part of the planned route, bringing fast high-capacity and clean transport into the busiest {CBD|Central Business District} precinct in the country.

We seek a step-change in Wellington's public transport, matching the vision of the {N2A|Ngauranga to Airport} ''Terms of Reference''. Our intention is to promote more discussion about the relative merits of light rail.

The identified route does not run by the Basin Reserve, although it is within the area defined in the N2A study. Recent events suggest difficulties in finding a reserved route, and multi-segment trains can be difficult on large, multi-lane roundabouts. This corridor is more suited to buses, with no particular reason to run a high-capacity route that way.

We seek a step-change in Wellington's public transport, matching the vision of the ''N2A Terms of Reference''. Our intention is to promote more discussion about the relative merits of light rail.

South of Constable Street we propose a route to Kilbirnie by either Wellington Zoo or Constable Street and Crawford Road (options 3a & 3b). In either case the proposed interchange is on commercial land at Coutts Street, opposite Bay Road. In this case the options have important cost effects, because of tunnels: option 3a will cost an additional $320 million. This area is discussed further in Sec(costs).

We suggest the costs set out in Tab(indicativeCosts) are reasonable, based on an all-up cost of $40 million per route kilometre,  including depot and vehicles but excluding tunnels. We have assumed that all interchanges can be built within this all-up cost, bearing in mind the value of residential development around a main interchange. Note that there are some rounding errors.

At the city end, we propose either a dedicated right of way on the west (Terrace) side of Lambton Quay, crossing to Jervois Quay at either Willeston Street (if practical) or Panama Street, or a waterfront route along Customhouse Quay. See Fig(innerCityMap), options 1a and 1b. Principal considerations in deciding which option will be vehicle speed, walking distance and passenger numbers walking. Further investigation is needed to determine whether a dedicated light rail route on Lambton Quay south of Panama Street is feasible, as this would require removing buses from this part of Lambton Quay.

* Ground conditions are such that the tunneling cost estimated for Mt Victoria is applicable.

The cost of a single-track light rail tunnel is given in the Spine Study as $316 million for 2 x 784m tunnels, 6.5 m OD, or $200,000/metre.[^Option Cost analysis, page 8^] This figure is used for the Mt Albert tunnel (option 3a) and runway tunnel (option 3b). However, option 3b is likely to need a double-track tunnel beneath the airport runway.

We believe light rail is superior to large buses for most transport along the spine, given Wellington's geography. Our calculations project comparable set-up costs and less expense to run.

In the southern CBD we propose either a Cuba St route or the straight and therefore quick route via Taranaki St (options 2a and 2b), moving on to Wallace St to allow access to Wellington High School and Massey University; then on to Newtown via John and Riddiford Streets via Wellington hospital. A route running east of the Basin Reserve would be better aligned with the features identified by French planners, with more opportunities at the Hospital and through Newtown.

We identify grave deficiencies in the business plan for {BRT|Bus Rapid Transit} and the spine study on which it is based: the proposed route bypasses where people live, and involves expensive tunnelling through Mt Victoria, with destruction of town belt and housing eastwards. We provide alternative routes which bypass the choke point at the Basin Reserve.

We seek a step-change in Wellington's public transport, matching the vision of the ''N2A Terms of Reference''. Our intention is to promote discussion about the superior merits of light rail.

As a result of our research, we present two workable routes, although we acknowledge that other routes are also possible. We suggest that the Golden Mile should be part of the planned route, taking fast high-capacity and clean transport through the busiest {CBD|Central Business District} precinct in the country.

BRT for Wellington will not be rapid and will not satisfy [[internationally agreed features -> https://www.itdp.org/library/standards-and-guides/the-bus-rapid-transit-standard/]] for a bus system to qualify as BRT.

The capacity of the Brisbane busway is given as [[nearly 300 bus/hr -> https://en.wikipedia.org/wiki/Busways_in_Brisbane]], compared with only about 40 trams an hour for light rail running on-street: lower than for buses because there is rarely space to berth two trams. Light rail capacity depends on high-capacity vehicles, perhaps carrying around 300-400 people in Wellington. A few buses sharing a light rail route will disrupt route capacity, but excluding all buses from the central city may not be possible: Light rail needs a second route for the remaining buses.

Planned transfers at quality interchanges are necessary for light rail in Wellington as they are everywhere else in the world. Transfers will dramatically reduce bus-kilometres, mainly on the golden mile, allowing more and better services on remaining routes. Good interchange and timetable design minimizes transfer times,[^2009 Opus survey and 2011 Bus Review^] making many trips faster overall.

Transfers are a successful and uncontroversial feature of most overseas public transport systems. The claimed unpopularity of transfers in Wellington is based on unsatisfactory questions posed in the spine study without balancing information. This approach unnecessarily biased respondents against transfers, i.e.

And, of course, everybody wants faster, cheaper and much more reliable trips anywhere-to-anywhere. This was a fatuous question.

The identified route does not run by the Basin Reserve, although it is within the area defined in the N2A study. Recent events suggest difficulties in finding a reserved route, and long light rail trams tend to be difficult on large, multi-lane roundabouts. This corridor is more suited to buses, with no particular reason to run a high-capacity route that way.

For option 3a we propose a single track tunnel to Kilbirnie, justified because the heaviest light rail traffic will be in the city centre and a reduced service can be justified beyond Wellington Hospital. Capacity should be at least 12 trams an hour each way, or say 3500 passengers an hour. This can probably be increased after timetable modelling. A second tunnel will be needed if capacity is ever reached.

We note that BRT stops in Brisbane are twice the width of Manners Mall, and we anticipate that light rail in Wellington will be cheaper than the street-widening and amenity costs of BRT.

This proposal should be relatively inexpensive to build, given good project management and good control of nice-to-have costs:

* No costly structures needed, other than tunnels, costed separately. The heaviest other cost will be Wellington Railway Station.

* A waterfront route would push down costs because it avoids the worst areas for costly underground services diversions.

* Other cities have reduced costs up to 20% using joint procurement (Amiens and Caen for example) and Wellington may be well-placed to do the same by pairing with Auckland.

We suggest the costs set out in Tab(indicativeCosts) are reasonable, based on an all-up cost of $40 million per route kilometre,  including depot and vehicles but excluding tunnels. We have assumed that all interchanges can be built within this all-up cost, bearing in mind the value of residential development around a main interchange.

We have identified two feasible and affordable options for light rail and a supporting bus network. We are confident that we have identified workable options, combining buses and light rail, but have not identified a best or preferred option. We propose buses and light rail on fully separated routes, both on or close to the golden mile.

Buses could fill several roles:

Summarising the advantages of light rail as suggested here:

* Speed throughout the route, with a guesstimated travel time to the Airport of around 20-25 minutes.

* The best service provided where demand is greatest: the Te Aro mixed use development area; high residential density and education destinations in Mt Cook; existing and planned residential density around Adelaide Road; Wellington Regional Hospital; high-density mixed-use in Newtown; high residential density and planned revitalization in Kilbirnie.

* Excellent timekeeping at all times of day, making  consistent timetables and timed transfers practical.

* Very smooth ride. A common sight is standing passengers when there are plenty of seats.

* Quiet, with zero emissions from the vehicle and almost carbon-free running on electricity from renewable sources.

This is an option for buses and light rail in Wellington. Light rail runs from the Railway Station to Wellington Airport, taking over the busiest corridor, and the remaining buses in the central city are reduced to manageable numbers.
