This paper describes the evaluation and testing of the two INTERSAFE demonstrator vehicles developed and implemented for intersection driver assistance. The tests were carried out in three evaluation phases: sensor test, system test and user test. During the sensor test, sensors (laserscanner and video system) and the communication module were under investigation. The focus of this phase was to verify the sensor performance required for the INTERSAFE functions. The chosen sensors were fully suitable to fulfill the tasks in the INTERSAFE Intersection Driver Assistance System. The system test was carried out to check the system functionality before the user test. Because of the system layout, a false-alarm-free result had not been achieved. In average, the correct alarm rate of the intersection assistant system was 97% and for the traffic light assistant 90% for both demonstrators. In the last testing phase, sixteen subjects had driven the demonstrator vehicles on the test track and assessed the performance of the INTERSTATE Intersection Driver Assistance Systems. Generally (and in particular, male and older subjects) think the INTERSTATE systems are helpful and relieving. Subjects think Traffic Light Assistant is more helpful than Intersection Assistant. Intersection Assistant for left turn scenarios is rated more useful than the one for lateral traffic scenarios. The INTERSTATE systems would have helped the subjects in their daily driving and it was agreed that it would improve traffic safety and that they want to have them in their car.
