Knowra Vision Zero Vision Zero Vision Zero is a road-safety strategy that treats deaths and serious injuries as preventable and makes their elimination the central goal of transport planning.
Safe System approach : A road-safety framework that assumes people make mistakes and designs transport systems to prevent those mistakes from causing fatal harm. Vision Zero is a prominent policy expression of this broader safety framework.
Swedish road safety policy : The national policies through which Sweden has pursued safer roads, including its adoption of Vision Zero. Sweden’s policy history provides the strategy’s original national setting.
Human factors : The study of how human abilities, limitations, and behavior affect interactions with systems and environments. Vision Zero begins from the premise that human error is inevitable.
Traffic calming : Street design and management measures that reduce vehicle speeds and discourage through-traffic. Calmer streets can bring vehicle speeds closer to levels compatible with human survival.
Three Es of traffic safety : A traditional traffic-safety framework organized around engineering, education, and enforcement. Vision Zero shifts emphasis from separate intervention categories to shared system responsibility.
Road hierarchy : A street-planning approach that assigns different roles and safety expectations to roads based on their function and users. Classifying streets helps match speeds and designs to the risks Vision Zero seeks to control.
Claes Tingvall : A Swedish road-safety researcher and policymaker associated with developing and advancing Vision Zero. Tingvall helped shape the strategy and explain its systems-based approach.
Kinetic energy : The energy an object possesses because of its motion, increasing with its mass and the square of its speed. Crash energy rises sharply with speed, shaping the limits of survivable road design.
Complete streets : A street-planning approach that considers safe, accessible travel for people using different modes and abilities. It supports Vision Zero by including pedestrians, cyclists, and transit users in street design.
Road safety campaigns : Public communication efforts intended to influence behavior and reduce traffic risks. Campaigns alone cannot compensate for roads and speeds that make ordinary mistakes fatal.
