Data stream from signal with phase and timing information Cooperative ICA R D in Europe 42 European ICA work is focused within the INTERSAFE project which is part of the PReVENT 6FW Integrated Project. The project running from 2004 to 2007 includes automotive OEM partners BMW Renault PSA and Volkswagen and suppliers TRW and Ibeo. The project s objective to improve safety at intersections is being pursued through a combined approach of sensors that detect potential hazards plus sensors that localize the host vehicle within the situation. Vehicle-infrastructure communication is employed to exchange information about traffic weather road conditions and other key factors. German crash data used to focus the work shows that intersection crashes account for 15 of road fatalities but represent about 43 of the passenger cars involved in crashes. A large number of crashes relate to right of way issues such as yield and stop signs and crossing traffic conditions. The INTERSAFE consortium is mainly focusing on stop sign assistance traffic light assistance turning assistance and right-of-way assistance. Two system development approaches a basic intersection safety system B-ISS and an advanced intersection safety system A-ISS are being pursued they differ in complexity and time-to-market but have similar architecture. As shown in Figure the B-ISS approach uses two laser scanners one video camera and vehi-cle-to-infrastructure communication implemented on a VW Phaeton test vehicle. Additionally communication modules will be installed at selected intersections in Cooperative Approaches for Vulnerable Road Users 203 Figure Basic ISS vehicle integration in the INTERSAFE project.
