Is it possible to have zero traffic deaths in a year?
Is it possible to have zero traffic deaths in a year? Is it even probable? As it turns out, yes. Here’s an article on what Helsinki did in order to make this a reality:
Andrei, M. (August 1, 2025) “Helsinki went a full year without a traffic death. How did they do it?” ZME Science, https://www.zmescience.com/science/news-science/helsinki-went-a-full-year-without-a-traffic-death-how-did-they-do-it/ [Last accessed: 8/19/2025]
To quote from the article:
“A lot of factors contributed to this, but speed limits are one of the most important,” said Roni Utriainen, a traffic engineer with the city’s Urban Environment Division.
More than half of Helsinki’s streets have a speed limit of 30 km/h (approximately 20 mph). Half a century ago, the city barely had half of its area with a 50 km/h limit (30 mph). They gradually worked to reduce the speed limit, especially around schools and kindergartens.
Smarter street design also played a key role. Pedestrian and cycling infrastructure was prioritized for upgrades in recent years. More and more people started using public transit or bikes, or just walking. Substantial investments also made public transit more efficient and reliable.“Public transport in Helsinki is excellent, which reduces car use, and with it, the number of serious accidents,” Utriainen noted.
Another key component was bringing the police on board. Helsinki introduced automated traffic cameras and enforcement systems, which also helped bring down reckless driving.”
Safety or speed?
We start June by sharing a video on why safety and vehicle speed are incompatible:
I saw this video while browsing an article on “Dangerous by Design”. The article discusses a new publication where road designs are evaluated from the perspective of safety. Most of our roads have been designed with speed in mind. That is, how to facilitate the movement of motor vehicles to ensure they travel faster. Forgotten or, even worse, disregarded is the most important element of safety. Why do we widen roads or insist on higher speeds in populated areas or school zones? Such questions are not addressed directly or not answered at all by agencies in charge of planning, designing, constructing and maintaining roads and bridges. The same is true for agencies or units in charge of traffic regulations or management. The result not surprisingly is an increase in the number of road crashes, fatalities and injuries due to our roads being ‘dangerous by design’.

Lower speed limits may not slow drivers, a before-and-after study shows
I am sharing this article on drivers not reducing their speeds after speed limits have been lowered along certain roads. My first reaction after reading the article is that it is that perhaps in the US case, the after study was conducted quite early and before people have become aware, understood and adjusted to the lower speed limits. The responses or reactions to lower speed limits (particularly those posted or on signs) may vary among cities and countries. In the Philippines, where drivers and riders appear to be oblivious to speed limits, other interventions may be required including some types of traffic calming devices. This is very much a concern particularly in school zones where children are exposed to the risks of being run over by motor vehicles speeding along the roads and not minding the speed limits in the area.
