4.3 Long-term Goal

A Safe System will exist when road users are no longer exposed to death or serious injury on the network.

An Ethical Approach

The Safe System approach focuses on eliminating crashes that result in fatal or serious injury outcomes; that is, those crashes that are a major threat to human health. It draws upon the Swedish Vision Zero and the Dutch Sustainable Safety road safety visions and objectives. Safe System Principles provides information on other key elements of the Swedish and Dutch approaches.

Vision zero

The Swedish Vision Zero asserts that human life and health are paramount (Tingvall, 2005) and no long-term trade-off is allowed, reflected in the ethical imperative that “It can never be acceptable that people are killed or seriously injured when moving within the road transport system”. Tingvall (2005) notes that traditionally, mobility has been regarded as a function of the road transport system for which safety is traded-off. However, Vision Zero turns this concept around and resets mobility as being a function of safety (See References(Scope of Road Safety Problem)). That is: no more mobility should be generated than that which is inherently safe for the system. This ethical dimension reflects the principles accepted for workplace safety, where the effectiveness of the working process cannot be traded-off for health risks. Norway (NPRA, 2006), in adopting the Vision Zero goal, has highlighted the ethical approach underpinning it, i.e. “Every human being is unique and irreplaceable and we cannot accept that between 200 and 300 persons lose their lives annually in traffic”. Sweden is looking beyond Vision Zero as well, and in November, 2017 introduced "Moving Beyond Zero." Moving Beyond Zero is a major rethink of the Vision Zero policy and introduces an active transport advocacy campaign. 

Sustainable safety

The objective of the Netherlands Sustainable Safety approach (Wegman & Aarts, 2006) is to prevent road crashes from happening, and where this is not feasible, to reduce the incidence of (severe) injuries whenever possible.

OECD (2016) points out that while Vision Zero is based on an ethical principle to eliminate death and serious injury from the transport system, Sustainable Safety takes elimination of preventable accidents as the starting point and attaches greater weight to cost-effectiveness in determining interventions.

It is clear that this ethical position, which holds that the prime responsibility of a road authority is to support road users to reach the end of each of their trips safely, is being increasingly adopted by jurisdictions. The following literature supports the need for measures to save lives through achieving a ‘forgiving’ system:

  • Elvik (2004) notes that many road users die who are not behaving illegally (See Crash Causes), and road authorities have a responsibility to provide a road network which is safe to use in accordance with the road rules.
  • Allsop (2008) refers to the scandal of public and political tolerance of crash risks on the world’s road networks, and the need to deal with new ways to address this disproportionate and affordably removable risk in everyday life.
  • The Tylösand Declaration (2007), which is set out in Scope of the Road Safety Problem states that everyone has the right to use roads and streets without threat to health or life.

Long-term Goal

The Safe System’s ethical goal of serious casualty elimination will not be achieved overnight. It requires a long-term timeframe for actions to be developed and implemented in successive intermediate timeframes, to deliver incremental serious casualty reductions (to meet interim targets over the medium-term) and support progress towards the long-term goal. The following case studies from Belize and China show two long-term approaches to reducing fatal and serious crashes.

CASE STUDY - Belize: "Safe Systems" demonstration Corridor for Belize 
In 2011, the government of Belize embarked on an ambitious safe system project that mobilised key action across the key pillars of actions and a focused upgrade to the safety of 370 miles (almost 600km) of road corridors. The Safe System project included road safety mentoring, capacity building and monitoring and evaluation. iRAP assessments were undertaken on key high-risk national highways. Public awareness campaigns were developed and enforcement equipment purchased with supporting legislative changes and emergency personnel were also trained. Read more (PDF, 650 kb).
CASE STUDY - China: "Highway Safety to Cherish Life"  
The Chinese Government has initiated an ambitious “Highway Safety to Cherish Life” investment across the country. The initiative includes partnerships at the national and provincial level focused on measuring the safety of infrastructure and targeting investment to save lives. To support the initiative, ChinaRAP has been established by the Research Institute of Highway (RIOH) and Ministry of Transport (MoT). Read more (PDF, 571 kb).

It also requires commitment to interim step-wise targets, which gives prominence to the long-term goal (OECD, 2016; GRSF, 2009; 2012; Breen, 2012).

PIARC (2012), in its National Road Safety Policies and Plans Report, notes that best practice in target setting is represented by government commitment to a long-term goal of zero fatalities with strong interim targets that establish the path to success. Adoption of a long-term Safe System approach is identified good practice for managing for results and is supported by other key international road safety stakeholder organisations as outlined in Road Safety Management. Following the request of the United Nations General Assembly, on November 22, 2017, member states reached consensus on 12 global road safety performance targets. For more information see Developing Global Road Safety Targets. There is an increasing number of countries that have adopted a “Towards Zero” or fatal and serious injury elimination goal — the aspiration underpinning the Safe System approach. This long-term commitment to elimination of road crash fatalities and serious injuries at the highest level of government will influence and support road safety management and road safety policy in a jurisdiction and will be clearly reflected in the proposals described in a strategy and action plan to achieve ambitious interim targets. The following case study from the United States of America, discusses the Minnesota's Towards Zero Deaths initiative. 

CASE STUDY - USA: Towards Zero Deaths (TZD) initiative 

From 1995 to 2003, Minnesota traffic fatalities were on the rise. Had the trend continued, by 2015 Minnesota expected over 700 traffic fatalities. At the 2001 North Star Workshop, Minnesota’s traffic safety leaders and professionals committed themselves to changing the trajectory of traffic fatalities. This workshop brought together experts from Minnesota traffic safety professionals, advocates, researchers, and experts from Washington, Sweden, and Australia. This workshop built the sense of urgency and energy to develop the Minnesota Toward Zero Deaths (TZD) program. Read more (PDF, 580 kb).

Putting Safe system into practice

The safe system approach often requires road agencies to rethink their approach to how projects and programmes are implemented. It is important to begin with some understanding of the how the system is currently operating through objective performance measurement. The first case study discusses the Road Safety Manual which was developed to help the practitioner on the Safe System journey. Some nations have also started the journey through the "Star Rating" system developed as part of iRAP. This is shown in the second case study.

CASE STUDY - Global: Road Safety Manual 

The PIARC Road Safety Manual provides detailed advice on the key elements of safe road design, the systems to support safer roads, targeting of action and proven infrastructure treatments. The Manual highlights the need to link Policy with Standards and Guidelines to ensure effective implementation. The UN Decade of Action for Road Safety Global Plan highlights the need to raise the inherent safety and protective quality of road networks for the benefit of all road users. Read more (PDF, 748 kb).
CASE STUDY - Global: Making safety a global standard 

Star Ratings provide an evidence-based objective measure of crash risk to ensure that safety is built-in to designs for upgrades and new roads prior to construction. For governments and development banks, the process opens the opportunity to set performance-based targets for vehicle occupants, motorcyclists, pedestrians and cyclists that not only improve safety but create a high level of transparency and accountability. The impact of raising high-risk road networks to a 3-star or better standard will deliver long term savings in death and serious injuries, and hospital and insurance costs whilst also providing a positive way for Governments to track performance. Read more (PDF, 587 kb).
