Cyclists
Examples of what City Safety interprets as a cyclist
— with clear body outline and bicycle outline.
Good performance requires that the system
function that detects a cyclist must receive the
clearest possible information about the body
and bicycle outline, requiring the ability to
identify the bicycle, head, arms, shoulders,
legs, upper and lower body plus a normal
human pattern of movement.
If large parts of the cyclist's body or bicycle
are not visible to the function's camera then
the system cannot detect a cyclist.
For the function to be able to detect a cyclist,
he/she must be an adult and riding a bicycle
designed for adults.
WARNING
City Safety is supplementary driver sup-
port, but it cannot detect all cyclists in all
situations and, for example, cannot see:
•
partially obscured cyclists.
•
cyclists if the background contrast of
the cyclist is poor – warning and brake
interventions may then be late or not
occur at all.
•
cyclists wearing clothing that obscures
the body outline.
•
bicycles loaded with large objects.
The driver is always responsible that the
vehicle is driven correctly and with a safety
distance adapted to the speed.
Pedestrians
Examples of what the system regards as pedestrians
with clear body outlines.
Good performance requires that the system
function that detects a pedestrian must
receive the clearest possible information about
the body outline, requiring the ability to iden-
tify the head, arms, shoulders, legs, upper and
lower body plus a normal human pattern of
movement.
In order that it shall be possible to detect a
pedestrian there must be a contrast with the
background and this will be affected by such
things as clothes, the background and the
weather. With poor contrast the pedestrian
may either be detected late or not at all, which
may mean that warnings and braking are late
or omitted.
City Safety can also detect pedestrians in the
dark if they are illuminated by the car's head-
lamps.
