COMPARISON OF HEALTH vs AUTOMOTIVE SECTORS FOR SAFETY

COMPARISON OF HEALTH vs AUTOMOTIVE SECTORS FOR SAFETY   NEXYAD poposes a comparison between HEALTH and AUTOMOTIVE sectors approaches for safty improvement. In particular, we explain that criticality assessment is very different from risk assessment: one notion (criticality assessment) is linked to emergency situations, and that the other notion (risk assessment) is linked to normal situations and the question "how to behave in order to avoid emergency situations". Here is the presentation:   Read... [Lire la suite]

SELF-DRIVING CAR MUST DRIVE "WELL" IN REGULAR CONDITION … SOUNDS EASY ? READ THIS BEFORE AND THEN TELL

SELF-DRIVING CAR MUST DRIVE "WELL" IN REGULAR CONDITION … SOUNDS EASY ? READ THIS BEFORE AND THEN TELL Human drivers don't have the sharp reflexes of ADAS. But they have only 1 accident in average every 100 000 km and 3 fatalities in average every billion km (OECD). Drivers that have the best reflexes are in average the Young ones - 18 to 25 - (biology). However, they also have much more accident than the 50 years old drivers (not as fast as they used to be when they were 20). Well, it seems that finally road safety is not... [Lire la suite]

FOUR SHADES OF ROAD SAFETY : ANTICIPATION, ADAS, PASSIVE SAFETY

FOUR SHADES OF ROAD SAFETY : ANTICIPATION, ADAS, PASSIVE SAFETY Here is a diagram of different shades of road safety. The pyramid witdh corresponds to the number of cases. "Normal" driving is the regerence, is is the most frequent situation, while fatality is fortunately an exception. Tools among the pyramid are filters made to avoid fatality :.

AI should help increasing road safety for robot taxi allowing to put them in function soon

AI should help increasing road safety for robot taxi allowing to put them in function soon Robot taxis are under testing in many cities such as Phoenix Arizona. Globally it works but the issue is still the rate of accident. Human driver has an accident in average about every 70 000 km and there are about 3 deads every billion km. This very high performance of human driver makes it difficult to automate driving, especially in urban traffic where road infrastructure characteristics are very complex. This explain why tests long more... [Lire la suite]
