Zero Pathway Development
How to Develop Zero Pathways
A Zero Pathway is a jurisdiction-specific, long-horizon roadmap for eliminating road deaths and serious injuries—built by applying the Planning for Zero Framework (PfZF) to a particular jurisdiction’s context.
It is not a generic “Vision Zero statement” or a standard action plan. It is:
- A tailored strategic response to the jurisdiction’s systemic risks and safety gaps, defined against a Safe System End State (SSES) and validated via residual risk analysis.
- Comparable to a road safety strategy and action plan, but with a key difference: it explicitly plans long-term strategic response from today to the adopted Safe System End State target horizon (commonly expressed as 2050), while also supporting interim targets (e.g. 2030), using a structured approach (baseline future trauma → residual trauma → additional interventions needed).[1]
- Context-specific by design: jurisdictions vary in challenges, resources, and capacity—so “one size fits all” is inappropriate. Zero Pathways incorporates unique jurisdictional circumstances, capability and capacity, and road safety strategy needs and cycles.
In short, a Zero Pathway translates the PfZF blueprint into a practical, sequenced, and monitorable pathway for your jurisdiction.
How could a jurisdictional practitioner develop an effective Zero Pathway?
PfZF is the core planning blueprint: it combines Safe System analysis, backcasting, and road safety intervention and performance monitoring, and it treats enabling institutional functions (management, engagement, investment, etc.) as essential—not optional. See the PfZF Technical Steps Guide.
Step 1 — Specify the desired future Safe System End State (SSES)
Adopt the good-practice definition of “zero harm”, as suggested in the Glossary of Terms & Definitions, and the 2050 zero target, then specify SSES based on human biomechanical tolerance for injury outcomes.
Practitioner intent: make the end state explicit enough that you can later test gaps and residual risks.
Step 2 — Validate the end state and analyse residual risk
Quantify how much serious trauma the SSES eliminates and identify residual fatal or serious injuries not addressed by the SSES assumptions (infrastructure, speeds, vehicles, etc.).
Practitioner intent: ensure the end state is more than an aspirational diagram. Step 2 tests the proposed SSES against real fatal and serious-injury crashes to show which crash scenarios would still produce death or serious injury under the assumed infrastructure, speeds and vehicle safety, and to explain why (e.g., limits of current technology, operating conditions outside design assumptions, incomplete rollout, or unresolved crash types). This helps practitioners refine the end state and identify where additional measures—or innovation—are needed.
Step 3 — Systemic risk and safety gap[1] analysis
Compare the current system against the SSES to identify systemic differences and jurisdiction-specific challenges, based on trauma characteristics.
Practitioner intent: turn your crash/trauma story into a “system story” that can be acted on.
Step 4 — Strategic response and pathways (this is where the Zero Pathway is formed)
Develop the pathway to zero as the strategic response to systemic risks and safety gaps:
- Establish the business-as-usual (BAU) baseline of future fatalities and serious injuries (FSI), reflecting current and already-planned measures and expected changes.
- Apply the proposed strategic response (e.g. a new action plan) to the BAU baseline to estimate FSI prevented and the FSI remaining over time, and how these results track against interim and end-state targets.
- Identify additional interventions and enabling actions—and their scale and sequencing—needed to further reduce the remaining FSI and close any gap to the targets.
Practitioner intent: build a long-term reform and investment program that is credible, sequenced, and grounded in the “gap to target”.
Step 5 — Performance monitoring and governance
Create a monitoring framework with performance indicators and output indicators tailored to the pathway, and pair it with governance that assigns accountability when progress is off-track.
Practitioner intent: make the pathway governable—measurable, owned, and reviewable.
The PfZF provides 11 recommendations to enhance jurisdictions’ maturity and capability to more effectively adopt and apply the PfZF’s steps. See the table below.
Table 2.1 Jurisdictional maturity improvement recommendations in order to apply the PfZF
| # | Primary & Related Secondary Recommendations | Detailed Recommendations |
|---|---|---|
| 1 | Primary 1: Vision Setting | Adopt definitions for Zero Harm, Serious Injury and Network Safety Plan as outlined in this project in road safety strategy development and monitoring/evaluation. |
| 2 | Vision Setting: Secondary | Jurisdictions to consider international best practice and include a target of zero road trauma by 2050, as well as ambitious interim targets for serious trauma in their road safety strategies. Jurisdictions also need to accept the need for transformational changes in order to achieve these targets. |
| 3 | Primary 2: Data Management | Develop the data management system necessary to undertake development of a pathway to zero trauma (Planning for Zero Framework). As a minimum, this needs to include fatal and serious injury crash data, in-depth trauma data, relevant road asset and hierarchy data for the arterial and local road network, relevant vehicle fleet safety data. |
| 4 | Data Management: Secondary | Jurisdictions to set up a framework[1] and develop the capacity to undertake ongoing in-depth crash investigations for fatal road crashes, to enable the analysis of residual risks and case-by-case trauma modelling. The focus in these investigations should be to systematically analyse injury mechanisms and causes of fatal outcomes to understand and take action to address system gaps in line with international best practice. |
| 5 | Primary 3: Planning for Zero Framework | Jurisdictions are to adopt a Planning for Zero Framework, including the steps recommended in this report. |
| 6 | Planning for Zero Framework: Secondary | Each jurisdiction is to utilise the Safe System End States identified in this project and bring together key stakeholders to define a Safe System End specific to their jurisdiction. |
| 7 | Planning for Zero Framework: Secondary | Jurisdictions should validate their Safe System End State by analysing residual risks to understand why some future severe crashes are still expected to occur and to ensure that risks are reduced to the tolerable levels required by the targets set for 2030 and 2050. |
| 8 | Planning for Zero Framework: Secondary | Jurisdictions to undertake a gap analysis (by mapping the developed Safe System End States against their current road network) to understand the gap in all system components between the current road system and the future Safe System End State. |
| 9 | Planning for Zero Framework: Secondary | Jurisdictions to utilise the validation of the Safe System End States and the Systemic Risks and Safety Gaps to develop evidence-based and empirically derived pathways that achieves near-zero outcomes long term while at the same time achieves near-term trauma targets. |
| 10 | Planning for Zero Framework: Secondary | Jurisdictions to develop a Performance Monitoring Framework in relation to the identified pathway to achieve zero trauma. In addition, implement a road safety management system that triggers action in response to the follow-up of indicators. |
| 11 | Primary 4: Road Safety Management | Jurisdictions to undertake a similar documentation of enablers and blockers for all institutional management functions listed in the World Bank Global Road Safety Facility (GRSF) guidance relevant for their organisation. This includes the identification of all barriers against the adoption and implementation of strategic responses based on the Safe System End State and identify enablers to overcome these barriers. |
For a mainly state-government-level practitioner, this becomes a practical entry point:
- assess your jurisdiction’s progress/alignment with the recommendations (maturity)
- assess where help is needed most (needs)
- use the output to prioritise maturity-improvement actions.
How to use this practically: treat the maturity/needs results as the implementation staging logic for your Zero Pathway. For example, if your monitoring system is weak (Rec 10), your pathway should explicitly include “build measurement + governance capability” as an early reform stream, not as a footnote.
See the Key Capability Improvement Activities for a suggested list of maturity-improvement actions developed as part of the Charting a Path to Zero project.
According to the PfZF’s blueprint, successful application of the framework depends on enabling aspects alongside the technical steps:
- Road safety management capability (coordination, legislation, funding, promotion, knowledge transfer)
- A systematic way to identify enablers and blockers
- Robust data systems for planning, implementation and monitoring.
This aligns tightly with several recommendations from Table 2‑1, especially:
- Data management minimum set (FSI crash data, in-depth trauma data, road asset/hierarchy data, fleet safety data)
- Building capacity for in-depth fatal crash investigation to support residual risk analysis and case-by-case trauma modelling
- Documenting enablers/blockers across institutional functions using Austroads guidance (i.e. Best Practice Guidance in Road Safety Management and Leadership: Proven Initiatives and Case Study Examples).
Practitioner takeaway: an “effective” Zero Pathway isn’t only a list of interventions; it is a capability-building and governance program that makes those interventions feasible and sustained.
To be consistent with the framework’s intent and structure, a jurisdictional Zero Pathway should usually include, as a minimum:
- Vision and targets: zero by 2050 + interim targets, grounded in agreed definitions (and positioned as requiring transformational change).
- SSES: defined and validated end state assumptions for your network/context.
- Systemic risk & safety gap profile: your “why we’re not safe yet” system diagnosis.
- Strategic response to 2050:
- BAU baseline → residual trauma → additional interventions/reforms needed
- A staged program (e.g., 0–5, 5–10, 10–25 years), with sequencing that reflects feasibility and capacity.
- Monitoring + governance: SPIs/output indicators and accountability mechanisms that trigger action when performance is off track.
- Enablers/blockers plan: what must change institutionally to deliver the pathway (funding, legislation, coordination, capability, etc.).
Kep Capability Improvement Activities
These activities are intended to help jurisdictions lift maturity and readiness to apply the PfZF’s technical steps (end states → validation/residual risk → safety gap analysis → strategic response/pathway → performance monitoring), and the enabling aspects (institutional functions, enablers/blockers, and data systems).
Use this artefact to:
- prioritise near-term capability uplifts (what to do first)
- shape the scope of supporting guidance, tools, and training
- inform “what help is needed” conversations with internal executives, partner agencies, and Austroads committees.
The actions below are drawn from the findings of the Charting a Path to Zero project, based on interviews and desktop analysis, and presented in priority order (highest first).
Table 2.1 Priority actions to support Zero Pathway development and implementation
| Priority Order | Action Item |
|---|---|
| 1 | Develop a suite of Safety Performance Indicators (SPIs) that should be monitored to assess progress towards a pathway to zero. |
| 2 | Develop a process or framework of generic enablers and blockers for assessment purposes. |
| 3 | Produce materials targeted at a political level to attract bipartisan support for the planning for zero framework. |
| 4 | Guidance notes on the importance of Network Safety Plans. |
| 5 | Guidance on the importance of road safety data and how to collect and use this for a results-based approach is needed. |
| 6 | Guidance on the in-depth investigation option would be useful. |
| 7 | Create clear, direct guidance for senior managers and decision makers on the importance of the pathways approach, including the benefits that are captured. |
| 8 | Develop a clear, graphical high-level planning document that can articulate the vision and benefits of PfZF and Safe System End States and seek national high-level consistency on this 2050 vision. |
| 9 | Create clear and generic end state models that can be adapted for local conditions, including step-based guidance (from lessons in the Stream 1 work). |
| 10 | Provide advice on how end states can be mapped incrementally across networks, including guidance on the need to prioritise this based on key systemic risks. |
| 11 | A plan is needed to identify residuals and solutions to these. |
| 12 | Need information on steps to link hospital data (difficult short-term). Guidance on the update of the police data collection form (overseas experience) would be a quick win. |
| 13 | Guidance on the benefits of PfZ and on making this a part of ‘business as usual’ is needed. |
| 14 | Produce guidance on highly effective interventions. |
| 15 | Guidance is needed on the analysis methods to identify optimal and cost-effective intervention packages, preferably as part of Network Safety Planning or Action Planning. |
| 16 | Guidance on the importance of targets is needed (easy to produce, but low priority for many). |
| 17 | Guidance is required on how to operationalise the SSES, especially logic-checking and implementation guidance on the theoretical desktop analysis. |
| 18 | Provide details on boundary conditions for 2050 beyond vehicle, speed and infrastructure (e.g. land-use planning, suicide prevention, etc). |
| 19 | Guidance on setting targets that link bottom-up and top-down methods is needed, but it is of low priority. |
| 20 | Guidance is needed on how to sense-check gaps before program implementation and adoption. |
| 21 | Guidance is needed on the quantification of FSI gaps under different scenarios for communication purposes to highlight the scale of the road safety problem. |
| 22 | Guidance on sense-checking and mapping interventions to the network based on the desktop review is needed. |
| 23 | Analyse the gap between implementation costs and current budgets to highlight the adequacy of current funding levels. |
These actions are designed to increase the practical “do-ability” of Zero Pathway development by particularly strengthening:
- performance monitoring and governance capability (e.g., indicator suites)
- the ability to diagnose and respond to institutional enablers and blockers (including political conditions and decision environments)
- the data and evidence foundations needed for residual risk analysis, gap analysis, and intervention optimisation
- development of end states that are consistent but adaptable, and implementable across real networks.
