For a long time, especially in Nepal, the general public and elected policymakers have operated under the assumption that human error is an inevitable cost of mobility. If someone on the road speeds, misjudges a turn, or steps off a footpath at the wrong moment, the resulting injury is often framed as a consequence of individual fault. We know of a history in which transportation companies measured their success and efficiency by the amount of steel moved from one point to another, while the human losses along the way were treated as collateral damage.
That framework is no longer viable. As our cities struggle with climate change, rapid urbanisation and social inequality, road safety can no longer be managed from a single perspective. It is not merely an engineering problem; it is a human rights issue, an environmental imperative and a central pillar of sustainable development.
If we intend to build equitable, low-carbon societies, our approach to road policy must fundamentally change. We must abandon the old habit of prioritising speed over survival.
Why the old model won’t work
To understand where policy goes wrong, we must first look at who is most vulnerable on our roads.
The World Health Organization reports that more than 1.1 million people die on the world’s roads each year. But those numbers hide a stark imbalance. More than half of all traffic deaths involve people who are not occupants of four-wheel vehicles. They are vulnerable road users — pedestrians, cyclists, and motorcycle and scooter riders. In rapidly urbanising nations, that proportion can rise sharply.
The global fatality rate, with fewer than 40% of deaths involving four-wheel vehicle occupants and more than 60% involving other road users, illustrates this disparity.
This disparity reveals a clear policy failure. For decades, urban design has prioritised car ownership as an engine of economic progress. Highways have not been kind to lower-income neighbourhoods, pedestrian crossings have been lengthened or sometimes eliminated to keep traffic flowing, and public transport has received minimal funding. In the Nepali context, funding has also not always reached where it was intended to go.
The result is a gap in mobility. The poorest citizens — those who walk or use two-wheelers out of economic necessity — bear the greatest physical risk so that others can commute quickly.
When a family’s primary breadwinner is killed or disabled in a traffic crash, the economic shock can propagate through generations. Children may be pulled from school, medical debts can mount, and household stability can collapse. Road violence does not just occur on infrastructure; it also undermines Sustainable Development Goal 1, No Poverty, and Goal 10, Reduced Inequalities.
Moving from “Safe Drivers” to “Safe Systems”
Where should modern transport policy go from here?
The answer lies in a paradigm shift that began in Scandinavia and has since gained global momentum: the Safe System Approach, often operationalised through Vision Zero.
Traditional road safety policy spent decades attempting to make human beings better road users through public awareness campaigns and punitive fines. The Safe System framework flips that logic entirely.
The core premise is simple: humans are inherently fallible. They will make mistakes, miscalculate speeds and experience moments of distraction. A truly sustainable transportation system must therefore be designed so that when human error inevitably occurs, it does not result in death.
Under a Safe System model, responsibility shifts from the individual road user to the system designers — planners, civil engineers and lawmakers who set speed limits and shape streetscapes.
If a driver hits a pedestrian at 50 km/h (31 mph), the pedestrian’s chances of survival are less than 20%. Drop that speed limit to 30 km/h (18 mph) through narrow lanes, raised crosswalks or speed tables, and survival rises to more than 90%. Such interventions rely on street design rather than a driver’s goodwill.
Climate action and road safety
Historically, environmental policy and traffic safety were treated as completely separate fields. Environmental writers covered emissions and green spaces; transport analysts covered asphalt projects and crash statistics.
Today, those two worlds are inseparable. Transport accounts for roughly 14% of global greenhouse gas emissions. Decarbonising this sector requires more than swapping petrol- and diesel-powered cars for battery-electric ones. Replacing a million gasoline-powered sedans with a million electric sedans may reduce tailpipe emissions, but it leaves urban gridlock, spatial inefficiency and pedestrian deaths largely unaddressed.
True sustainability requires a structural shift in how people travel — most importantly, moving away from single-occupancy vehicles towards mass transit, active travel and micromobility.
However, people will not walk or cycle if they believe doing so puts their lives at risk.
The relationship works like this:
Safe, protected infrastructure
↓
Higher rates of walking and cycling
↓
Reduced vehicle miles and air pollution
↓
Healthier, more equitable communities
A government that builds wide, high-speed roads while encouraging people to cycle for the climate is sending a contradictory message. On the other hand, when a municipality redesigns a corridor to include protected bike lanes, wide sidewalks and dedicated bus lanes, it can achieve two goals at once.
Direct safety: Physical separation protects vulnerable users from heavy vehicular traffic.
Climate action: Reduced car dependency directly lowers urban carbon footprints and local air pollution.
Overcoming policy resistance
Implementing these changes is rarely straightforward. Technical solutions are of little use if they cannot survive political debate.
Reallocating street space away from motorised vehicles will often trigger public pushback, particularly from those who currently benefit most from that space. Small business owners may worry that removing street parking will hurt foot traffic, despite evidence that pedestrian- and cyclist-friendly environments can support local businesses over time. Commuters may resist lower speed limits, viewing them as deliberate inconveniences rather than life-saving measures.
To bridge this gap, policymakers must reframe road safety as a broad public health issue rather than a series of isolated traffic rules.
Consider how societies have approached smoking or seatbelt use. Meaningful change does not happen purely through individual choices; it requires clear legislation, public health messaging and structural changes that make the safer choice the natural one. The same approach applies to city streets.
Rethinking modern streetscapes
The modern road cannot remain an arena where speed takes priority over human life.
As we move towards the Sustainable Development Goals, which specifically call for halving global road deaths and providing safe, accessible transport for all, policy must align with reality. A street that is unsafe for a nine-year-old child to walk alone or for an elderly resident to cross confidently is not a finished piece of infrastructure. It is a system failure.
As future policymakers, urban designers and transport scholars take on these challenges, the guiding principle must remain straightforward: mobility should never demand human sacrifice.
When we design streets that protect the most vulnerable, we do more than reduce crash statistics. We create quieter, cleaner and more resilient cities where everyone can move freely and safely.
