IWAY: Towards highway vehicle-2-vehicle communication and driver support

This paper describes the Alert Manager subsystem which merges information coming from: (i) an in-vehicle sensing system, (ii) the road infrastructure and (iii) neighbouring vehicles to generate high level and useful information for car drivers. The subsystem is a part of the I-WAY system, whose aim is to provide drivers with timely warnings and meaningful suggestions to avoid potential hazards in the driving environment. The Alert Manager can efficiently handle multiple information sources, fusion of complementary data and management of incoming events´ priorities. Moreover, the Alert Manager controls the broadcasting of messages to keep Road Infrastructure and other vehicles updated about potential hazards. We focus on the determination of the dominant risk prevailing in the road environment.
