Singapore's road deaths are rising. The answer isn't more cameras.
Singapore does not lack enforcement. The question is whether enforcement, speed policy, and road design are working together as a fail-safe system.
Singapore recorded 149 road deaths in 2025 — the fourth consecutive year of rising fatalities and a 10-year high. The policy response has been familiar: more speed cameras, higher fines, and public education campaigns urging road users to be more careful. These measures are not without value. Enforcement and education influence behaviour and signal social norms. But evidence from Singapore and other global cities suggests a crucial distinction:
Enforcement changes behaviour temporarily.
Road design and speed policy change behaviour permanently.
The cities that have successfully reduced road deaths over long periods did not choose one or the other. They combined enforcement, lower speeds, and safer street design — but they placed the greatest emphasis on the measures that work continuously, not intermittently.
Eight cities, one consistent pattern

Looking across cities such as Helsinki, Tokyo, London, Paris, and Shenzhen, road deaths have generally fallen over the past decade. Cities such as Hong Kong, New York City, and Singapore have seen flatter or worsening trends in recent years.
The difference is not that some cities enforce traffic laws and others do not. All of them use cameras, fines, and enforcement operations. The difference is what sits at the centre of the safety strategy.
In cities where fatalities fall steadily, the strategy usually includes:
Lower urban speed limits
Traffic calming and fail-safe street redesign
Automated enforcement with high certainty
Systematic crash investigation
Network-level policy changes rather than isolated programmes
Enforcement exists everywhere.
But enforcement alone has not been sufficient anywhere.
Temporary behavior change vs permanent behavior change
Education campaigns and enforcement operations can change behaviour quickly, but the effect often fades. When enforcement intensity drops or drivers learn camera locations, behaviour adapts again.
Infrastructure and road design work differently. They influence behaviour continuously and subconsciously. Drivers naturally slow down when:
Lanes are narrow
There are raised crossings
Trees or buildings are close to the road
Junctions are frequent
The road visually feels local rather than highway-like
Drivers do not think about it — they simply adapt to the environment.
This is why traffic calming and lower-speed street design produce long-lasting safety improvements, while campaigns must be repeated every year.
The lesson is not that campaigns are useless.
The lesson is that campaigns cannot carry the safety system by themselves.
Singapore’s own data already shows what works
Singapore already has one of the clearest case studies in its own policy toolkit: Silver Zones.
Silver Zones include:
30-40 km/h speed environments
Raised crossings
Narrowed carriageways
Traffic calming features
These zones have reduced senior pedestrian accident rates by around 80 per cent. This is an extremely large safety effect by international standards.
Another example comes from heavy vehicle speed limiters.
Where speed is physically limited, speeding violations drop to near zero. Where speed relies on enforcement detection, violations still occur.
These two examples illustrate a consistent safety principle:
The most reliable way to reduce dangerous behaviour is to design the system so dangerous behaviour is difficult or impossible.
This principle is used in aviation, workplace safety, and industrial safety. Road safety is no different.
The speed limit and the reality of Singapore traffic
Singapore’s urban speed limit is generally 50 km/h, but Land Transport Authority data shows that average speeds on arterial roads are around 28 km/h.
This is important because on signalised urban roads, journey time is determined mainly by:
Traffic lights
Queue lengths
Bus stops
Turning traffic
Pedestrian crossings
Not by the maximum speed between junctions.
A driver who accelerates to 50 km/h usually arrives at the next red light earlier, not sooner. This is why many traffic engineering studies show that reducing speed limits on signalised urban roads often has little effect on overall travel time.
In practice, Singapore roads already operate closer to 30 km/h than 50 km/h. The higher speed limit mainly affects the speed vehicles reach between junctions — which is also where the most severe crashes occur.
This creates a situation where the speed limit influences crash severity more than travel time.
The enforcement gap: the 10 km/h buffer problem
There is another issue that is rarely discussed publicly but is important for policy effectiveness: the practical enforcement buffer.
In Singapore, exceeding the speed limit by around 10 km/h is often treated as a minor violation in practice. Many drivers understand this and treat the effective speed limit as speed limit + 10 km/h.
This creates a policy contradiction.
If the posted speed limit is 50 km/h but enforcement effectively begins at 60 km/h, then:
The real operating speed becomes 55–60 km/h
The safety benefit of the 50 km/h limit is largely lost
The speed limit becomes a guideline rather than a limit
Cities that successfully reduced road deaths treat the speed limit as an actual limit, not a target with a wide tolerance.
This does not mean enforcement must be punitive. But it does mean consistency and certainty matter more than occasional large penalties.
ERP 2.0: Singapore may already have the solution
Singapore is currently rolling out ERP 2.0, a satellite-based electronic road pricing system that tracks vehicle movement continuously rather than at fixed gantries.
ERP 2.0 is primarily designed for congestion pricing, but it also creates a new possibility: network-wide, continuous speed enforcement instead of camera-based spot enforcement.
Traditional speed cameras enforce speed only at specific points. Drivers slow down near cameras and speed up afterwards. This is known internationally as the “kangaroo effect”.
A satellite-based system could instead measure average speed over a road segment, which is much harder to evade and encourages consistent speeds rather than braking only at camera locations.
If used this way, ERP 2.0 could:
Reduce the need for more roadside cameras
Enforce speed limits consistently across the network
Remove the camera-location guessing behaviour
Make enforcement more certain but less visible
Align actual driving speeds with posted limits
In other words, ERP 2.0 could shift Singapore from point enforcement to system enforcement.
That would be a major structural change in how speed limits are enforced.
The real policy issue is not enforcement vs infrastructure
The discussion is often framed as:
Cameras vs road design
Enforcement vs infrastructure
Drivers vs pedestrians
But this is the wrong way to frame the problem.
The cities that improved road safety the most did not choose one tool.
They changed the centre of gravity of their road safety policy.
Instead of relying mainly on:
Enforcement campaigns
Penalties
Awareness campaigns
They relied mainly on:
Lower urban speeds
Traffic calming
Safer crossings
Road design for lower speeds
Consistent automated enforcement
Enforcement still existed. Campaigns still existed.
But the system did not depend on perfect behaviour to prevent deaths.
Road safety is about design tolerates human mistakes
Every road system must assume that people will:
Look at their phones
Misjudge gaps
Cross slowly
Ride unpredictably
Speed occasionally
Make errors at junctions
If the system only works when everyone behaves perfectly, it will not be safe, because human do make mistakes.
The safest road systems are designed so that when mistakes happen, people are injured less severely or survive.
Speed is the most important factor in whether a crash becomes a fatality.
That is why speed policy, road design, and enforcement must work together.
The question going forward
Singapore already has:
Strong enforcement
Road safety campaigns
Silver Zones
School Zones
Traffic calming programmes
Advanced road pricing technology
Detailed traffic data
Strong transport planning institutions
Singapore does not lack tools.
Singapore does not lack data.
Singapore does not lack enforcement.
The policy question is this:
Should enforcement and campaigns remain the primary road safety strategy, or should Singapore gradually shift towards lower urban speeds, traffic calming at scale, and system-wide speed enforcement using new technology?
That is not an engineering decision.
That is a policy direction decision.
The cities that reduced road deaths consistently made that shift over time.
They did not abandon enforcement, yet they changed what enforcement was supporting.
The difference is subtle, but important:
One approach tries to make road users behave perfectly safe and no mistakes allowed.
The other approach tries to design a road system where natural user behavior, sometimes with mistakes are less likely to be fatal.
That difference often determines whether road deaths fall, stagnate, or rise over the long term.
