Abstract: The new safety paradigm, Vision Zero is built around the basic idea that even if not all traffic crashes can be avoided, all severe injuries can, in principle, be avoided. Building a "safe system," where all predicted crashes have tolerable health losses, requires a new roadway design philosophy. This new philosophy calls for shifting from the traditional preventing crashes to preventing health harm. This shift calls for switching from designing roads to have space for evasive action to managing the kinetic energy transferred in crashes to human bodies to be within its injury tolerance.
