Exploitability of vehicle related sensor data in cooperative systems

This paper shows how extended vehicle related sensor data is gained and used within the cooperative system developed in the project KOLINE. This system aims at coordinating traffic in order to achieve a reduction of delay and emissions in urban networks by exchanging information between traffic signals and approaching vehicles. Besides receiving information about the signal program and traffic state at the intersection the vehicle also uses data of multiple sensors and different sensor technologies. This allows the creation of a redundant representation of the vehicle´s environment which is used to improve the vehicle´s approach to intersections. Additionally, the information can be used by the infrastructure to improve the performance of the adaptive traffic control system by using it for tailback approximation and for the calibration of the underlying traffic model.
