Vision Zero: a Revolutionary Approach to Road Safety
Looking for inspiration to improve road safety in your city? The Vision Zero movement continues to grow in the world. A few years for an ambitious but achievable goal: 0 traffic death on the roads!
“Because human life is priceless!” This could be the slogan of the international Vision Zero approach. Born in Sweden in 1997, this revolutionary approach to road safety aims to reduce the number of people killed and seriously injured on the roads. How? By placing the responsibility for the risks of accidents on the designers of the road and not only on its users. From Stockholm to Toronto, through the largest cities in the United States, dozens of cities have joined the Vision Zero movement around the world. We invite you to discover this concept of a city primarily centered on respect for human life!
Different Strategies for Road Safety
The Vision Zero approach is based on a simple principle: fatalities are preventable, so they are unacceptable. This is to eliminate all causes of foreseeable accidents during the design or rehabilitation of the road network. The protection of life and human health is non-negotiable and is at the forefront of any other benefit (traffic flow, travel speed, etc.). The designers of the road networks must then make every effort to secure the travel of all, without forgetting the most vulnerable users: children, the elderly, people with disabilities or reduced mobility. While it is unrealistic to want to remove all accidents, it is almost always possible to limit their impact on the physical integrity and health of the victims.
3 Flagship Measures: Reducing Speed, Securing Roads and Raising Awareness Among Stakeholders
To succeed in your Vision Zero project, you should better proceed in stages. Before establishing an action plan, it is necessary to involve all stakeholders under strong and determined leadership. This is the approach adopted by the city of Montreal by forming a dedicated team, with 7 additional hires, and by forming a steering committee bringing together the most influential players in road safety. The next step is to analyze accident data in order to identify the risks and hazards present on the road network. The analysis of these data serves as the basis for the action plan.
Travel Speeds Adapted To The Infrastructure
The higher the speed, the greater the risk of mortality. The maximum speed in a given area is therefore calculated according to the characteristics of this area and adapted to the type of users:
⊗ In areas with motorized vehicles alongside pedestrians, the speed must not exceed 30 km/h (19 mph). This is the limit not to be exceeded for a pedestrian to have a chance of survival in a collision. It is even recommended to lower it to 20 km/h (12 mph). If the maximum permitted speed is greater, the pedestrian routes must be physically separated from the traffic lanes.
⊗ In areas with many intersections where vehicle crossings are possible, the speed must be less than 50 km/h (31 mph). Beyond that, a side impact can be fatal. At 50 km/h (31 mph), pedestrian flows must be protected.
⊗ In less dense traffic areas, with rare intersections, the recommended speed limit is 70 km/h (43 mph).
⊗ Finally, a speed greater than 100 km/h (62 mph) can only be justified when traffic lanes in opposite directions are clearly separated, eliminating any risk of frontal impact.
Measures To Eliminate Road Hazards
Street users should never be at risk of accidents as long as they follow the rules. This is the foundation of Vision Zero philosophy. It is the responsibility of the designers of the road to prevent as much as possible all the dangers. Some examples of measures to put in place:
⊗ Reduce the presence of motorized vehicles in the city;
⊗ Secure pedestrian crossings;
⊗ Upgrade the traffic lights using the most advanced technologies: digital countdown, activation of Accessible Pedestrian Signals for the blind and visually impaired, possibility of increasing the duration of the crossing for people with reduced mobility, etc. ;
⊗ Improve lighting;
⊗ Regulate the traffic of alternative modes and Personal Light Electric Vehicles (PLEVs), such as electric scooters, hoverboards, Segways, skateboards, etc. ;
⊗ Secure school surroundings;
⊗ Improve cycling conditions.
By reversing the traditional vision of road safety, the Vision Zero approach implies a change in mindsets among the decision makers and designers of the road and its users.
For the benefit of users, the city of Montreal has issued a charter of good conduct on which everyone can commit to road safety.
San Francisco’s LightHouse for the Blind and Visually Impaired has launched its own awareness campaign to remind drivers of the right of way for pedestrians with a white cane or guide dog when crossing the street.
250 stakeholders have already joined the global Vision Zero movement.
Speed reduction, securing roads and educating stakeholders, there are countless measures to make the city safer for all its users.
The success of a Vision Zero project comes first and foremost through political commitment, the coordination of stakeholders and the scrupulous monitoring of actions.
