ABSTRACT:
During the last
decades, the total number of vehicles in our roads has experienced a remarkable
growth, making traffic density higher and increasing the drivers’ attention
requirements. The immediate effect of this situation is the dramatic increase
of traffic accidents on the road, representing a serious problem in most
countries. New communication technologies integrated into modern vehicles offer
an opportunity for better assistance to people injured in traffic accidents.
Recent studies show how communication capabilities should be supported by
artificial intelligence systems capable of automating many of the decisions to
be taken by emergency services, thereby adapting the rescue resources to the
severity of the accident and reducing assistance time. To improve the overall
rescue process, a fast and accurate estimation of the severity of the accident
represent a key point to help the emergency services to better estimate the
required resources. This paper proposes a novel intelligent system which is
able to automatically detect road accidents, notify them through vehicular
networks, and estimate their severity based on the concept of data mining and
knowledge inference. Our system considers the most relevant variables that can
characterize the severity of the accidents (variables such as the vehicle speed,
the type of vehicles involved, the impact speed, and the status of the airbag).
Results show that a complete Knowledge Discovery in Databases (KDD) process,
with an adequate selection of relevant features, allows generating estimation
models able to predict the severity of new accidents. We develop a prototype of
our system based on off-the-shelf devices, and validate it at the Applus+ IDIADA
Automotive Research Corporation facilities, showing that our system can notably
reduce the time needed to alert and deploy the emergency services after an
accident takes place.
