Looking into the Path Future: Extending CAMs for Cooperative Event Handling

Research output: Chapter in Book/Report/Conference proceedingConference paperpeer-review


Cooperative driving is a key enabler for safe and efficient
driving. The European Telecommunications Standards Institute
(ETSI) published standards for message dissemination and
packet formats for continuous status notification, i.e., Cooperative
Awareness Message (CAM), and asynchronous event notification,
i.e., Decentralized Environmental Notification Message (DENM).
Cooperative Intelligent Transportation Systems (C-ITS), such as
platooning, rely on these messages that are exchanged between
vehicles and infrastructure. However, CAM and DENM do not
target cooperativeness: future paths can not be shared. Therefore,
in this paper we present a modified CAM structure that allows
a vehicle to indicate its own future trajectory over a variable
spatial and temporal horizon. It may be used in combination with
DENM to cooperatively handle events and limiting their impact.
The presented approach is tested in simulation using Omnet++
and Simulation of Urban Mobility (SUMO) considering an IEEE
802.11p network.
