Answer
In Sustainable Safety five safety principles have been specified: three design principles and two organization principles.
The three design principles are:
- Functionality of roads: road sections and intersections have only one function: a traffic flow function or an exchange function.
- (Bio)mechanics: limiting differences in speed, direction, mass and size and protection of the road user.
- Psychologics: aligning the traffic environment with road user competencies.
The protection of and feasibility for vulnerable road users (cyclists and seniors in particular) are important starting points for a more detailed elaboration of these safety principles.
The two organization principles are:
- Responsibility: responsibilities are laid down unequivocally and are in line with the tasks of the parties involved.
- Learning and innovating: traffic professionals continuously examine the causes of crashes and develop effective and preventive system innovations based on this research.
The traffic professional plays a central role where all these principles are concerned.
