different worldwide regulations and consumer tests are considered during a car development project- far away from harmonisation


14/16


Fisita 2008

pedestrian protectionexample for a standardized test approach

active safety is lacking of standards

repeatable test scenarios must be developed to evaluate systems

the potential of systems must be evaluated in a new efficiency approach

-> accident research has to look into the future (and not in the past)

Conclusion I

Fisita 2008

on boardsystems

Vision Zero: accident prevention by use of

vehicle tovehicle-communication

vehicle toinfrastructure-communication

> high income contries:

> developing contries:

investment in infrastructure and re-newing car fleet;adaption of integrated safety approaches


16/16


Conclusion II

> integrated safety systems

> first systems are at the market

> offer high potential to enlarge benefit and efficiency of today's protection systems

> future actuators for integrated safety systems should be an essential

emphasis of the development

> test procedures as well as simulation surroundings of integrated safetysystems are necessary for the future
