Extended Peer-To-Peer-based Traffic Information System
Recently a whole community consisting of public authorities, academia,
and car manufacturers has formed in
pursuit of improving driving security and comfort by enabling inter-vehicle
communication. Proposed applications span from the reduction
of road casualties by means of brake warning, intersection assistance,
or collision avoidance systems to offering guidance to
available parking lots, discovering the traffic
situation on a planned route, and coordinating
car flow and traffic lights.
In this project, we focus on non-safety applications that can be
subsumed under the term distributed traffic information systems (TIS).
Such applications aim to improve the driving comfort by
enhancing a driver's awareness regarding the current traffic conditions
and enabling dynamic route guidance
In Peer-to-peer TIS the participating cars are not only consumers of
information but at least some of them also produce information by
sharing their observations. An observation is, for instance, a local
measurement of the current traffic conditions or the number of
currently free parking slots, which is then distributed to other
TIS usually rely on communication among many participants over
relatively large geographical distances that can span some ten kilometers in the
case of a city scenario up to some hundred kilometers on highways.
Furthermore the provided information need to be up-to-date what makes
the implementation of the system even harder.
In this project, we use infrastructure-based communication to build a distributed, cooperative TIS - only requiring
every participant to maintain an Internet connection.
We envision such a solution based
on distributed hash tables, i.e., on peer-to-peer technology: a huge
peer-to-peer network of vehicles. Such a system, implementing
well-designed distributed data structures and algorithms allows to
build the scalable TIS application.
X-PeerTIS is conducted with support of the DFG within the Project: "Car-to-Car Communication via Infrastructure-based
Peer-to-Peer Networks" (DFG 560198)
