TOOWOOMBA REGIONAL COUNCIL: THE LEVEL OF SERVICE JOURNEY FOR ROAD SERVICES
Justin Weligamge Principal Engineer – Asset Management for the Toowoomba Regional Council Infrastructure Services Department
Graham Jordan Director Lemmah Pty Ltd
Abstract
Toowoomba Regional Council (TRC) was established in 2008 with the amalgamation of eight former councils. The Toowoomba Region is the centre of some exciting new initiatives in transport including the newly opened Wellcamp Airport, the Second Toowoomba Range Crossing and the proposed Melbourne to Brisbane Inland Rail project. To maximise the benefits of these major projects, seamless integration with the TRC local road system will be critical. A key aspect of this integration is to have a clear understanding of the concept of level of service across the transport network. Key levels of service criteria identified include road safety, business expectations and community expectations.
TRC has adopted a strategic asset management approach to the management of its road system and completed the first phase of its asset management plans for Roads, Footpaths, Bridges and Stormwater in 2012. These plans utilised industry best practice guidelines but in their current form still need significant development to better support Council long term financial planning. A key shortcoming of the current asset management plans is a lack of documented Levels of Service (LOS) for the road network and linkages of financial projections to the long term financial plan.
The TRC LOS journey commenced in 2015 to develop a LOS framework for the TRC road network and then to implement the framework for the TRC road network.
This paper presents an overview of the LOS project journey, the results, challenges and lessons learnt to date.
Key Words:
Levels of Service Strategic Asset Management Road Services Long Term Financial Plan Sustainability
INTRODUCTION Toowoomba Regional Council (TRC) is a local government located 125km west of Brisbane on the Darling Downs. It was established in 2008 with the amalgamation of eight former councils. The Toowoomba Region is the centre of some exciting new initiatives in transport including the newly opened Wellcamp Airport, the Second Toowoomba Range Crossing and the proposed Melbourne to Brisbane Inland Rail project. To maximise the benefits of these major projects, seamless integration with the TRC local road system will be critical. A key aspect of this integration is to have a clear understanding of the concept of level of service across the transport network. Key levels of service criteria identified include road safety, business expectations and community expectations.
With a total area of 12,973 km2 and 6,565km of roads (50% of which are unsealed). The current status of the TRC road network is summarised in Figure 1. TRC has adopted a strategic asset management approach to the management of its road system. TRC completed the first phase of its asset management plans for Roads, Footpaths, Bridges and Stormwater in 2012. A key shortcoming of the current asset management plans is a lack of documented Levels of Service (LOS) for the road network and linkages of financial projections to the long term financial plan. TRC is committed to the implementation of strategic asset management processes based on ISO 55000 and industry leading practices as documented in publications such as the International Infrastructure Management Manual (IIMM).

The TRC LOS journey commenced in 2015 to develop a LOS framework for the TRC road network and then to implement the framework.
The objectives of the project include:
1. To develop a guide on how the LOS framework can be implemented in a pragmatic way for the TRC
road network.
2. To engage with key internal and external stakeholders in the development of LOS
3. To examine the financial impact with the adoption of different LOS scenarios
4. To develop long term renewal and improvement funding estimates for the TRC long term financial plan
5. To develop an appropriate asset management plan template incorporating the LOS framework and
funding estimates
THE LEVEL OF SERVICE JOURNEY Development and implementation of levels of service commenced in 2015 and Figure 2 shows a flowchart of key activities for this project.

Approach—LOS for Transport Assets
LEVELS OF SERVICE
Community Levels of Service
The Concepts Communities generally describe services subjectively in terms of what they value about a service (outcomes) rather than what Councils do (activity). Since not all communities want the same things at the same time, their perceptions of service value and quality will vary, as well as their satisfaction with the levels of service Council provides. Developing levels of service is all about managing expectations. Where there is a mismatch between Community's’ perceptions and expectations, an expectation gap is created. This gap can be real or perceived.
Where Community's’ service performance perceptions are significantly less than their expectations, they become dissatisfied with the current level of service, and judge it to be of poor quality.
These gaps become the service drivers. The concepts are illustrated in Figure 3.
Figure 3: Community Levels of Service Concepts
Community Services Levels are developed from the relevant transport network and link level service drivers. Each service driver is linked to a service objective which is in turn linked to service benefits. Critical success factors link objectives to benefits and tell us if our service delivery is achieving the objectives. Service delivery is concerned with the assets, staff, systems, processes, procedures and programs which provide the services. Key performance indicators link service objectives to service delivery. Technical levels of service and other service enablers assist with service delivery.
Community Level of Service Objectives Community LOS objectives relevant to TRC need to be confirmed through internal and external engagement. A consultation kit will be developed to inform participants in the consultation process. The kit will include background information on the TRC road network including its extent, traffic, condition, projected demand and current funding levels. TRC prepares an annual transport Asset Status report which already provides a lot of this information. A recommended draft of Community LOS objectives for consultation is provided in Table 1.
Table 1: Draft Community Levels of Service Criteria
The success of Community LOS objectives is based on how well they achieve the expected benefits.
These are the Critical Success factors.
Examples of Critical Success Factors include:
Improving community satisfaction with roads
Growth in regional economic activity
Reduction in fatalities and serious accidents
Stable travel times on major routes
Improving satisfaction with road environs
Reduction in noise and dust complaints
For Community LOS, measurement utilises trends in regional economic data, road safety statistics, development statistics, customer surveys and customer request system data to determine if the expected benefits are being achieved.
Technical Levels of Service
Concepts Matching infrastructure to service requirements is a complex process requiring consideration of all phases of the asset life cycle. To reduce this complexity and to ensure consistency across the network, road authorities translate community service requirements into technical levels of service.
Technical levels of service are driven by community levels of service, Council priorities, legislative and regulatory requirements; nationally developed standards based on best practice and locally based guidelines based on local experience. Technical levels of service specify how the organisation will respond to the external and internal service drivers. Technical levels of service are enabled by guidelines for initial investment, periodic replacement of key components and maintenance for the repair of defects.
The concepts are illustrated in Figure 4.
Figure 4: Technical Levels of Service Concepts
Technical Service Measures TRC has existing design guidelines, renewal targets and maintenance targets. These provide guidance on targets for road and structures for:
Capacity and configuration;

Aligning Community and Technical Levels of Service
For many local government services such as road services there is no direct link between funding and the level of services provided. Roads are funded along with other services from rate revenue supplemented by specific road grants from the State and Commonwealth governments. This detachment of level of service, funding and road service management strategy leads to misalignment of what is provided to what is desired to what can be afforded i.e. the level of service provided by the road network is not directly linked to what can be afforded by the community. Apart from minimum safety levels, technical levels of service can be modified to align with transport service levels that the community is prepared to fund (Figure 5). A structured community engagement process will be used to provide input to Council on what these levels should be.
Figure 5: Aligning Community and Technical Levels of Service
IMPLEMENTATION Technical levels of service are the mechanism through which service providers specify the service capacity and performance of infrastructure. Resources are allocated to deliver these services through the maintenance, renewal and improvement programs. The adopted LOS need to be financially sustainable in the long term. The road manager seeks to balance expenditure on maintenance; renewal and improvement over the long term to sustainable achieve the adopted levels of service (Figure 6).
Figure 6: Achieving Sustainability of the Road Network
Road Risk Rating
To facilitate the management of the road network, roads are allocated a risk rating. There are many risks associated with operating a road network including asset deterioration, driver fatigue, hazardous grades, and inadequate pavement strength etc.
Higher risk roads will have lower intervention levels and shorter response times for the repair of defects. Funding allocation is prioritised based on the level of risk. Initially, the TRC road network risk ratings will be aligned to road hierarchy as shown in Table 3. To manage risks, road assets need to be regularly inspected.
Table 3: TRC Road Risk rating
Road Hierarchy Road Risk Rating

Regional Arterial Very High

Road Management
The road network is managed at multiple levels:
Short term Maintenance Intervention parameters are set for various defects in terms of intervention level, response time and maximum defective condition. Different targets are recommended based on the road risk rating. To maintain road safety and protect the asset integrity, the road manager needs to initiate repairs within the limits established by these parameters.
Medium Term Renewal Intervention targets are established for each road link in terms of road characteristics such as strength, rutting, roughness skid resistance, surface texture, residual life and deflection. The road manager implements various rehabilitation treatments to maintain the road condition within the nominated targets. The draft TRC defect based targets are provided in Table 4. These targets will be reviewed based on feedback from the Community Engagement process.
Table 4: TRC Renewal Intervention Targets
Long term Improvement Based on the vision for the transport network over a 20 year period, individual link visions and functions are developed. Services and infrastructure are selected that will deliver the function. A gap analysis is undertaken between the current configuration and condition and the vision configuration and condition. This identifies gaps which become potential projects. Investment strategies are developed which outline how the vision standards will be achieved over a twenty year period.
Planning Hierarchy
Transport network hierarchies are useful tools for network planning and management. Historically transport network hierarchies have been commonly used for providing functional road hierarchies to inform integrated land use and transport planning and management, and road network management hierarchies to inform infrastructure planning, design and management. Recently there has been increased interest internationally in developing a multi-modal transport network hierarchy to inform integrated network planning and management. The intent of this is to improve the extent to which the road network planning and management makes best use of the transport network through managing competing demands from different modes, including general traffic, freight, public transport and active transport.
Parsons Brinckerhoff in a report dated May 2014 proposed that TRC adopt a four level hierarchy which defines the multi modal functions of roads (
Table 5). Balancing the traffic and activity in streets is needed to ensure that they adequately service the surrounding land use as well as their traffic function. Streets are classified by the adjoining land uses that they serve and the place that they form part of, irrespective of their traffic function.

Road Service Profiles Level 3 of the four level hierarchies are Service Profiles. Standard service profiles are a predefined group of service targets which are designed to deliver the link vision. Typical characteristics include design speed, heavy vehicle type, maximum grade, bus route etc. The recommended service profiles are based on the IPWEA publication “Complete Streets” and are detailed in Table 7 .

The transport planning concepts of “link” and “place” can be implemented using service profiles. A “link” looks at a street as a movement conduit, while “place” looks at a street as a destination for other no traffic uses such as walking, cycling, entertainment or eating.
Road Asset Profiles Standard road asset profiles are a predefined group of assets which are designed to deliver the target service levels. These profiles have traditional been termed “standard drawings”. The existing TRC Road Asset Profiles are aligned to road hierarchy and are summarised in Table 8.

Putting it into Practice
As part of this project we are looking at an approach which allows for a range of standards based on the 4 level hierarchy and incorporates the link and place concepts. The approach is illustrated in Figure 7 and Figure 8 and uses a number of steps.

assigned to each road link within the network. The adoption of road management priorities facilitates and simplifies service planning. The allocation of a road management priority gives Council officers clear directions on how Council sees the network being maintained and developed. Allocation of road management priorities is a strategic decision and needs to be endorsed by senior management and Council. For every road management priority there is a complementary road service and asset strategy. A draft set of road management priorities and associated service and asset management strategies are summarised in Table 9

As a first stage of implementation, Figure 9 provides three scenarios which allocate road management priorities at the macro road network level based on road hierarchy and traffic volumes. The percentage allocated to each priority varies between each option. The funding (improvement, renewal and maintenance) associated with each of these scenarios can be calculated and compared with the available funding in the 10 year financial plan.

Figure 9: Road Management Priority Allocation Options
For the second stage Priority 1 and 3 roads are specifically identified and all other roads are allocated Priority 2. A road management priority list is prepared. A Road Management Priority is assigned to each road link within the network. Based on the adopted priority road managers select the appropriate improvement, renewal and maintenance targets to apply. The adopted strategies are documented in the TRC “Road Management Priority” list. The “Road Management Priority” list specifies the roads and extent of each road which will be improved, renewed and maintained based on the adopted service management strategy. The “Road Management Priority” list will be endorsed by Council as part of the Transport Asset Management Plan.
ALIGNMENT WITH LONG TERM FINANCIAL PLAN
Road Network Sustainability
Using the adopted Road Management Priorities and Technical LOS, modelling is undertaken to calculate the projected long term funding for road maintenance, renewal and improvement over the investment period. This projected funding is compared to the funding available for roads determined by Councils long term financial modelling. If in balance, the network is being managed sustainably.
What options does the road manager have to achieve to achieve sustainability if the projected funding exceeds the available funding?

CONCLUSIONS Toowoomba Regional Council has commenced the journey to formalise levels of service for its 6563km road network. Faced with the challenge of managing such a large road network, TRC has adopted a strategic asset management approach which is based on prioritising the road network and assigning level of service targets based on these priorities.
The TRC’ strategic approach includes three key steps:
1. Use Road Management Priorities to prioritise the network.
2. Use assigned Service Targets to determine the desired and acceptable levels of service for each
priority.
3. Use an Asset Management System to examine alternative funding scenarios based on these priorities.
A structured community engagement process will guide the implementation of this strategy.
