Autonomous mobile entities, for example automated
guided vehicles, are playing an increasingly important role in
our everyday lives. Since these entities share their environment
with each other and with humans, they need to coordinate
their behaviour to ensure that strong safety constraints are
respected. However, as sensing range and accuracy are inherently
limited, and communication in wireless networks is unreliable,
autonomous entities have access to only limited information about
their environment and the current behaviour of other entities.
This makes ensuring system-wide safety constraints particularly
In this paper, we show how system-wide safety constraints can
be translated into requirements on the behaviour of individual
entities depending on the information available. We first present
a formalism to express high-level system-wide safety constraints.
We then introduce a notion of distributed responsibility allowing
requirements on the behaviour of individual entities to be
deduced. We show how this process can be applied to an example
from the Intelligent Transportation System (ITS) domain.
