|Submissions for this consultation is now closed.
The NZ Transport Agency consulted, on behalf of the Minister of Transport, on proposed changes to Land Transport Rule: Vehicle Dimensions and Mass 2002.
Consultation on the proposed changes was carried out to ensure that legislation was sound and robust and that the rules development process takes account of the views of, and the impact on, people affected by proposed rule changes.
As patronage increases on bus services in Auckland and elsewhere, extra capacity cannot be provided by simply adding more conventional buses.
The introduction of higher-capacity vehicles (such as double-decker buses) has been suggested as an appropriate way to meet the additional demand. These buses can take more passengers, but their axle loadings exceed the limits currently allowed in the Vehicle Dimensions and Mass Rule.
The proposed amendment would allow road controlling authorities (such as city or district councils, and Auckland Transport) to issue permits to larger urban buses, allowing them to exceed the current axle weight limits, but only where road surfaces are sufficiently robust.
The proposed amendments only apply to buses on scheduled routes approved by the relevant regional council or equivalent authority.
Submissions closed on Thursday 2 April 2015.
The proposed amendment to the rule will:
The proposed amendments only apply to buses on scheduled routes approved by the relevant regional council or equivalent authority. Any permits issued under the proposed changes would not allow such vehicles to exceed their gross vehicle mass (GVM). The majority of the buses coming within the definition of 'urban bus' and likely to be the subject of applications for permits will be double-decker buses.
Consultation on the proposed amendment rule closes on 2 April 2015.
Following consultation, officials will summarise all submissions, and provide a report to the Minister of Transport on matters raised.
If the minister approves the rule, with any post consultation changes, it is anticipated that it will be signed by 1 June 2015 and that its provisions would come into effect on 1 July 2015.
The Government Policy Statement on Land Transport (GPS) sets out the investment priorities for transport across New Zealand. These are issued for a three-year term.
The current GPS supports the need for public transport to help unlock the potential of our urban areas by providing additional capacity on key corridors and a choice of ways to move around, particularly during peak commuting periods. This is particularly the case in Auckland, Wellington, and Christchurch.
In Auckland in the near term, there are capacity constraints around key corridors on the rapid and frequent networks such as the Northern Express.
These routes account for around 12 million passengers per annum, with growth in these corridors ranging from 6% to 10%, and peak capacity utilisation ranging between 80%–95%.
These trends are reflected in other metropolitan centres, but will take longer to reach over-capacity limits. Wellington will also need to address capacity constraints within existing corridors in order to meet public transport demand and its regional targets. In addition, Christchurch is experiencing severe congestion on some routes.
As buses reach capacity, they continue past people waiting at bus stops and this falls below an acceptable level of customer service.
The constraints which limit a solution based on higher frequency services (less distance between buses, more buses on each route) include:
The use of higher capacity vehicles, such as double-decker buses, is one option. Other initiatives include bus priority treatment along key corridors and within the city centre, and the further introduction of bus lanes and dedicated busways. These can be progressed alongside the introduction of higher-capacity buses.
This form of vehicle provides an approximately 50% increase in the number of passengers but imposes axle loadings beyond those currently allowed by the Vehicle Dimensions and Mass Rule 2002 (VDAM Rule). These are in regular use in a number of overseas metropolitan areas (for example London and Hong Kong) where road space is at a premium and passenger numbers are high.
A key advantage for this form of vehicle is that its 'footprint' is equivalent to existing conventional buses.
The potential disadvantages for operating double-decker buses are:
Note that the proposed higher axle limits assume a three-axle vehicle.
Double-decker buses would have to meet current requirements for vehicle length limits.
This form of vehicle also provides higher capacity, close to that of the double-decker buses discussed above.
Some of these vehicles do not meet the current axle weight limits stated in the VDAM Rule but, if appropriately designed, they can track through corners with a similar swept path to conventional buses.
Prior trials and evaluations (primarily in Auckland) of articulated buses, however, concluded that these vehicles create some disadvantages:
This form of vehicle is in wide use for urban bus services. A typical vehicle has three axles, with a total length of 13.5 m. These vehicles are already allowed a slightly longer overhang (the distance between the last axle and the back of the vehicle) than other heavy vehicles.
Effectively, these vehicles are at the limit of length versus their ability to fit on the available road network, especially in suburban areas.
This amendment rule does not propose the issue of permits to these vehicles.
This amendment rule deals with a specific issue (the introduction of high-capacity buses) and does not consider the wider question of allowable axle weights for existing buses or other vehicle classes.
Last year, the Ministry of Transport initiated a full review of the VDAM regime, and a public discussion document is scheduled for release later this year. The review is the appropriate mechanism for determining permitted axle weights for heavy vehicles.
The proposed changes will impose limited costs upon bus operators who apply for permits. Road controlling authorities (RCAs) will also have to create and consider a new class of overweight permit. However, these costs are expected to be offset by greater efficiency for the service provided and to ease congestion on the authorities' roads.
Higher-capacity buses provide greater passenger throughput on high demand routes and central city spaces. As noted above, this has higher net benefits if the routes travelled do not require extensive engineering work to accommodate larger vehicles.
The availability of permits, even though these are intended to be applied only on high-capacity routes, will provide the option for bus operators to consider the purchase of more productive vehicle types, which would not be allowed under the current VDAM Rule.
There will be marginal inefficiencies for the time required for loading and unloading of passengers at bus stops. These times increase whenever buses have to take on or offload high volumes of passengers at any stop, and will also increase where passengers have to go up to or descend from an upper deck. However, these inefficiencies are outweighed by the ability to operate at regular intervals with a reduced number of buses to meet the demand and frequency requirements on main corridors.
Higher axle loadings will impose greater wear (and therefore maintenance costs) on the routes where these vehicles will operate. This can be offset by increased revenue through road user charges (RUC).
There are two standard RUC rates for three-axle buses, for vehicles under or over 18 tonnes. However, these rates do not apply to vehicles operating above the usual VDAM limits.
Section 12 of the Road User Charges Act 2012 requires all heavy vehicles operating under overweight permits to carry RUC licences appropriate to the additional weight involved. At present no such licence rates are prescribed specifically for buses, but section 90A of the Road User Charges Act provides that in such circumstances the NZ Transport Agency can set an appropriate rate by notice in the New Zealand Gazette.
The amendment rule contains three proposals for your comment.
Proposal 1: Create a new definition of ‘urban bus’.
The definition is designed to include any bus with 60 or more passenger seats used in a scheduled service that is deemed integral to the public transport network and therefore included within a public transport plan by a regional council (or equivalent authority, such as Auckland Transport).
It is not intended to include buses providing inter-city services.
The distinction is made because of the need to protect infrastructure. Permits issued under this proposal could only be issued for urban routes with high-quality road construction which can withstand the higher wear created by the increased axle loads.
Permits would not be available for passenger coaches that will be travelling long distances along highways and secondary routes where the roads are not of uniform construction.
Permits would not be available for the conventional buses which are the most common vehicles currently used for urban services. These have a seating capacity (typically) of up to 48 passengers.
Proposal 2: Insert new section 5.2A to:
The existing HPMV definition refers to divisible loads in excess of the VDAM limit of 44 tonnes in combination. Even the largest buses considered for the proposed permits would have on-road weights around 23 tonnes. Passengers are a divisible load, so urban buses are aligned with the existing HPMV class.
For a bus which meets the definition, RCAs would be able to consider an application from a bus operator. Note that the RCA is under no obligation to issue a permit.
The section also provides some guidance on matters the RCA should consider when assessing any permit application, such as the suitability of the intended routes for such use.
In addition, the section emphasises that no permit can exceed the GVM for the vehicle, or other design limits. This is consistent with the existing 5.1 (indivisible loads) and 5.2 (HPMV) provisions.
Proposal 3: Insert new Part C in Schedule 2 that sets out maximum permitted axle weights for urban buses.
Permits already issued to HPMVs [5.2 in the Rule] cannot exceed axle weights as set in either Part A or Part B. The new table creates an equivalent set of limits for urban buses.
Note that only the weights related to tandem axle sets are increased over current limits in either Part A or Part B.
These higher limits would only be permitted for urban buses, and would not be available to other HPMVs.
|Proposed Part C
|Current standard limits (Part A)
Single standard tyred axle in any axle set
Single large-tyred axle in any axle set
Twin-tyred axle in any axle set
Two axles in a tandem axle set comprising:
|a. Twin-tyred axle with a single large-tyred axle and a 60/40 load share
|b. Twin-tyred axle with a single large-tyred axle and a 55/45 load share
Part A sets out a table of axle weights for vehicles operating without a permit. Part C would only be applicable to permits for urban buses, not other HMPV types.
As noted above, the current regulations include two rates for three-axle buses:
|Powered passenger service vehicle with 3 axles
|RUC weight of not more than 18,000kg
|RUC weight of more than 18,000kg
These rates are only valid for vehicles that do not exceed the standard axle weight limits set out in Part A.
Under this proposal, high-capacity buses will be able to operate under the higher axle weights permitted by the Part C limits. A new rate therefore needs to be set for the larger buses when operating on a permit.
Such a rate can be prescribed as part of new Road User Charges (Rates) Regulations that need to be made to implement any planned increase in charges from 1 July 2015. In the meantime an appropriate rate can be set by the NZ Transport Agency using the power provided in the Road User Charges Act 2012 to set rates by a New Zealand Gazette notice in cases where no applicable rate exists in regulations.
A further review would also be needed if operators wished to introduce vehicles with more than three axles (not currently anticipated).
An update to these schedules, arising from the 2014 amendment to the VDAM Rule which revised penalties applying to permit holders, is expected to be approved early in 2015.
Further minor changes may be required to the overloading tables (Schedule 1A and Schedule 1B) to ensure that buses operating on the proposed permits are correctly identified.
If the proposal is accepted, the NZ Transport Agency and other RCAs will need to make minor changes to their permit process, and reflect the purpose of the permit in any form issued. This does not require any further alteration to the VDAM Rule.
The Land Transport Act 1998 provides the legal framework for making land rransport rules. Section 161 states the procedures by which the Minister of Transport makes ordinary rules.
Section 164(2)(b) of the Land Transport Act 1998 requires that appropriate weight be given to the nature of the proposed activity or service for which the rule is being established.
The proposed activity is to permit the operation of urban buses with higher axle weights, at the discretion of an RCA.
Section 164(2)(a), (c) and (d) requires the minister to take into account the level of risk to land transport safety in each proposed activity or service, the level of risk existing to land transport safety in general in New Zealand, and the need to maintain and improve land transport safety and security.
The introduction of higher capacity buses will have a (small) safety benefit, when compared to the additional risk exposure created by adding greater numbers of buses on already congested routes. Higher passenger numbers on buses also have the effect of reducing the number of private vehicles using those routes at peak times. In addition, the rule will allow for newer buses to be imported replacing older vehicles currently on our roads which, as a general rule, means improved technology and safety features.
Section 164(2)(e) of the Land Transport Act 1998 requires that the minister have regard, and give such weight as he or she considers appropriate in each case, to whether a proposed rule:
Section 164(2)(ea) of the Land Transport Act 1998 requires that the minister have regard to the costs of implementing measures proposed in a rule.
Summary comments on costs and benefits are provided on page 8.
Section 164(2)(eb) and (f) of the Land Transport Act 1998 requires that, in making a rule, the minister must have regard to New Zealand's international obligations concerning land transport safety, and the international circumstances in respect of land transport safety.
The proposed amendment rule is consistent with New Zealand's international obligations.

Land transport rules (rules) are legislation made by the Minister of Transport or his or her delegate under the Land Transport Act 1998.
The Land Transport Act 1998 sets out principles and the policy framework; rules contain detailed requirements, including standards and processes, for putting those principles and policy into operation. Rules cover a range of land transport issues. Among the outcomes that rules aim to achieve are: safeguarding and improving land transport safety and security, improving access and mobility, assisting economic development, protecting and promoting public health and ensuring environmental sustainability.
Compliance with rules is required because they form part of New Zealand transport law. The specific offences and penalties that apply to each rule are set out in the act or in regulations.
This proposed amendment rule is drafted by the NZ Transport Agency, in close consultation with the Ministry of Transport. Rules are drafted to be understood by a wide audience and to help ensure compliance with requirements.
The NZ Transport Agency is responsible for ensuring that appropriate consultation is undertaken on proposed rules, and a draft rule may be refined in response to submissions received.
