Implications for Delivery
There are many policy areas where implementing Safe System will benefit Scotland more widely. To help realise these benefits practitioners should:
Prioritise system design over behaviour modification
Require systemic safety audits at the early stages of road and urban planning.
Mandate that all new roads and streets adopt "forgiving" design principles, including self-explaining layouts, traffic calming, and safe crossings.
Embed safe speeds in transport policy
Expand 20mph speed limits to other areas across Scotland beyond Edinburgh.
Set evidence-based speed limits on rural roads based on crash risk rather than road classification.
Link speed management to wider societal benefits, such as emissions reduction, to strengthen political and public support.
Collaborate across sectors
Establish multi-agency taskforces integrating health, environment, and transport sectors to co-design policies.
Integrate road safety performance measures into public health monitoring frameworks.
Promote active travel infrastructure as an investment in public health, not just transport.
Invest in safe infrastructure for sustainable transport
Guarantee dedicated annual funding for safe active travel infrastructure, separate from general transport budgets.
Make Safe System compliance a condition of funding for local and regional authorities.
Require "active travel impact assessments" for all major infrastructure projects.
Prioritise equity in road safety interventions
Focus Safe System interventions in areas of high deprivation and high casualty rates.
Engage under-represented groups meaningfully in road safety policy development.
Include equity impact assessments in all major road safety strategies.
Background
Historically, road safety policy focused on reducing accidents through enforcement, education, and engineering. The Safe System approach reframes the issue: the priority is not preventing accidents altogether but eliminating deaths and serious injuries. This shift leads to different priorities, designing the system to forgive human error through safer road layouts, lower speed limits, safer vehicles, and stronger integration with health, planning, and transport sectors. Embedding the Safe System into policy means decision-making is more holistic, with transport planning now placing vulnerable road users - pedestrians, cyclists, and motorcyclists - on an equal footing with drivers, supporting more inclusive and sustainable urban design.
The Safe System can help shape road safety policies in Scotland in many positive ways. There are also cases where policies were introduced that might have been more effective if the Safe System approach had been used at the time.
What the Research Shows
In Scotland, the Road Safety Framework to 2030 explicitly adopts the Safe System components: Safe Roads and Roadsides, Safe Speeds, Safe Vehicles, Safe Road Use, and Post-Crash Response. Policy now emphasises proactive risk management, targeting high-risk locations before collisions occur. This has wide-reaching societal impacts:
Health and wellbeing
The Safe System promotes public health by encouraging active travel - walking, cycling, and wheeling - through safer environments. Active travel supports better physical and mental health, reducing risks of obesity, heart disease, and depression (Ding et al., 2024; Kroesen & De Vos, 2020).
Edinburgh’s 20mph rollout (2016–2018), influenced by Safe System thinking, demonstrated clear co-benefits, including fewer casualties and increased perceptions of safety (Nightingale et al., 2021). Public Health Scotland now recognises transport policy as critical for advancing national health goals. By prioritising system design over individual behaviour, Safe System policies also address health inequalities, protecting children, older adults, and disabled people who are most vulnerable in traffic environments.
Economic
Serious road crashes cost Scotland over £1.1 billion annually, encompassing healthcare, policing, productivity loss, and long-term care. The Safe System’s focus on preventing death and serious injury, rather than simply reducing crashes, delivers major economic benefits.
Investments such as median barriers, cycle segregation, and traffic calming offer strong cost-benefit returns. Internationally, Sweden’s Vision Zero shows that embedding Safe System principles can reduce fatalities by 50–70% while supporting economic growth (Rosenthal, 2023).
Environmental
Safe System thinking supports environmental goals by making low-carbon travel modes safer and more appealing. Measures like speed reductions, traffic filtering, and segregated cycle lanes help cut emissions and improve air quality. Low Traffic Neighbourhoods (LTNs) in Glasgow and Edinburgh, influenced partly by Safe System principles, have improved safety while promoting cleaner air and reduced traffic (Low Traffic Neighbourhoods Research Report, n.d.).
Influence on other transport modes
The Safe System encourages safer conditions for emerging transport modes like e-scooters and cargo bikes. Streets designed for people first - not just cars - support a wider modal shift. Dundee’s Sustainable Transport and Health Plan exemplifies this: through segregated cycleways, traffic calming, and safer crossings, the city integrates Safe System principles to promote active and sustainable transport. Better pedestrian access to public transport also strengthens the case for reduced car dependency, aligning with Scotland’s climate and congestion targets.
Opportunities for improvement
While Scotland has made strides, some policies could have benefited more from a rigorous Safe System application. The controversy over Aberdeen’s bypass (AWPR), for example, highlighted tensions: while aiming to reduce traffic in city centres, the project risked encouraging increased car travel overall, with insufficient attention to safe access for active modes. A Safe System perspective might have led to stronger parallel investments in active and public transport infrastructure along with the road. Similarly, some rural road safety programmes still overly focus on driver behaviour (education campaigns) without sufficient systemic interventions (road design changes, speed management), which would better align with Safe System best practice.
Conclusions
The Safe System offers a transformative way to frame road safety policy. By designing a transport system that protects human life above all else, Scotland can deliver broad co-benefits: enhanced public health, economic savings, environmental improvements, and more sustainable mobility. Embedding the Safe System across transport, health, and climate policies will ensure that road safety is not isolated but central to creating a safer, healthier, and more sustainable Scotland. Stronger cross-sector collaboration and sustained political commitment will be vital to realising this vision.
