A method for determining a driving strategy for a driver of a motor vehicle includes receiving local information about a plurality of other motor vehicles using a receiving device, wherein the plurality of other motor vehicles are ahead of the motor vehicle and are relevant to the traffic situation. The method further includes recording the local i...

We describe a distributed and self-regulated approach for the self-organisation of a large system of many self-driven, mobile objects, i.e., cars in traffic. Based on methods for mobile ad-hoc networks using short-distance communication between vehicles, and ideas from distributed algorithms, we consider reactions to specific traffic structures (e....

As part of our project AutoNomos, we have investigated traffic information and management systems that motivate the usage of new methods and tools inspired by Organic Computing paradigms. Current traffic monitoring and management approaches with stationary infrastructure lack flexibility with respect to system deployment and have difficulties with...

In recent years, tremendous progress has been made in understanding the dynamics of vehicle traffic flow and traffic congestion by interpreting traffic as a multiparticle system. This helps to explain the onset and persistence of many undesired phenomena, for example, traffic jams. It also reflects the apparent helplessness of drivers in traffic, w...

Today Vehicular Ad-Hoc Networks (VANETS) are a promising field for increasing comfort and safety on the road. They have the potential to connect cars with each other and thereby extract information about road conditions or dangers that drivers can't ldquoseerdquo, e.g., the end of a traffic jam behind a curve. In this article we will focus on the p...

Traffic applications, in which vehicles are equipped with a radio interface and communicate directly with each other and the road traffic infrastructure are a promising field for ad-hoc network technology. Vehicular applications reach from entertainment to traffic information systems, including safety aspects where warning messages can inform drive...

We propose a decentralized traffic information system—Auto-Nomos—that is based on a thorough investigation of the properties of traffic and recommends a hierarchical data aggregation and forwarding for providing individualized information and support to road users. Our approach differs from work in the field by consequently applying local rules and...

With the change from wired to wireless technologies the complexity of computer networks increases significantly. Distributed applications built on top of these wireless networks must be well designed to work in this difficult and changing envi-ronment. Especially the ad-hoc wireless communication between devices with wireless transceivers based on...

Vehicular Ad-Hoc Networks (VANETs) enable communication among vehicles as well as between vehicles and roadside infrastructures. Currently available software tools for VANET research still lack the ability to asses the usability of vehicular applications. In this article, we present Traffic Control Interface (TraCI) a technique for interlinking roa...

For today's mobile applications in ubiquitous/pervasive environments, the classical client-server approach with tightly-coupled components does not suit anymore. Instead, new ways of information passing between such mobile components have to be searched: components will often have no dedicated communication partner, but rather send data into a cert...

Routing within wireless mobile multi-hop networks is a challenging task. Therefore, in the past several routing protocols have been developed with various extensions and adoptions to certain specific scenarios. The consensus of the discussion about routing is that depending on all aspects of their application reaching from number of nodes, mobility...

Protocols and applications that rely on unicast and multicast communication are well accepted and still gain more and more popularity. However, these communication paradigms are not optimal for a class of wireless applications where communication partners neither establish specific relationships nor need roles like client and server between each ot...

Many complex structures in our modern world exist independent of the individual entities they are composed of, giving them an "organic" quality. Important examples include traffic phenomena, e.g., traffic jams; despite of strong efforts over many years, centralized computing has been unable to deal with the resulting problems in a satisfactory mann...

With ever-increasing numbers of cars, traffic congestion on the roads is a very serious economic and environmental problem for our modern society. Existing technologies for traffic monitoring and management require stationary infrastructure. These approaches lack flexibility with respect to system deployment and unpredictable events (e.g., acciden...
