Enhanced Optimization of Traffic Flow and Traffic Safety by Means of Cooperative Control.

Abstract:

This paper presents a new concept for traffic flow optimization. Traffic flow optimization and road safety are attained by means of car2carcommunication and decentralized vehicle control in the form of a multi-agent system which initially excludes driver input. An optimal traffic situation respecting both traffic flow and traffic safety measures is assured using local (vehicle-level) control algorithms. Consensus algorithms form the core of these control laws. This allows a spatially distributed self-organized vehicles adaption to the current aggregate traffic variables through an ad-hoc communication network. An integral aspect is the mapping of aggregate traffic variables to vehicle-level state variables (such as relative positions, speed). A decision is made concerning a traffic flow optimized formation using game theory approaches and by modeling relative vehicle positions with Petri-Nets. Road safety is therefore improved by the self-adjusting inherent dynamics and the determined formations. This contribution has not been published anywhere else before and is approved by all authors.
