  • 1. Chalmers University of Technology Field Operational Tests From Data Collection to Analysis With Focus on Distraction Katja Kircher, Chalmers Foto: Tedd Soost

2. Chalmers University of TechnologyFOT a Hot Topic In Sweden and Europe now many FOTs underway Netherlands: Roads to the Future (ACC & LDW; 20 cars, 5 months, finished 2006???); LDWA FOT (35 trucks 1 coach, LDW) Sweden:ISA, TSS-FOT, SeMiFOT, (Distraction Project) EU:euroFOT, TeleFOT 3. Chalmers University of Technology In the US completed (examples) UMTRI (ACAS FOT, RDCW FOT) Volvo FOT, Drowsy Driver Warning System FOT ongoing (examples) IVBSS, CICAS-V, SafeTrip 21 (naturalistic driving: 100 car; SHRPII) 4. Chalmers University of TechnologyEvaluated Functionscomfort systems decreasing activity frequency ACC activity ISA Lane Change/Merge LDW, CSW (RDCW) criticality Drowsy Driver Warning FCW (IVBSS)event warning systems increasing criticality 5. Chalmers University of TechnologyDriver State So far not often a main factor in FOTs(except Drowsy Driver Warning SystemFOT, VTTI). However, FOT and naturalistic driving (ND)data useful to answer driver statequestions (e. g. prevalence in differentsituations) 6. Chalmers University of TechnologyDriver State Intoxication Drowsiness Distraction Illness Stress andFoto: Tedd Soostother mentalstates 7. Chalmers University of TechnologyDriver State Possible Questions prevalence during different situations/ events possible to warn before critical events occur? effect of warnings? general change of behaviour? long-term effects, e. g. system abuse validation of simulator/test track findings 8. Chalmers University of Technology Driver State FOT Difficulties not easy to log in real time(necessary to give real time warnings/info) not even easy to log reliably at all(e. g. stress, intoxication, ) 9. Chalmers University of Technology FOT and Distraction Visual distraction accessible via eyetrackers (gaze direction), which by now aremature enough for field use Distraction quite common in everydaydriving (reasonable FOT duration enough) Distraction difficult to provokenaturally somewhere else thanin field (FOT method of choice) 10. Chalmers University of TechnologyFOT and Drowsiness Drowsiness accessible via eyetrackers (blink behaviour),which by now are mature enough for field use Drowsiness not so common in everyday driving(FOT duration? Special driver selection?) Drowsiness in field/natural environ-ment qualitatively different thanforced drowsiness in simulators? 11. Chalmers University of TechnologyFOT for Studies of Driver State + natural environment + long-term observation of behaviour(adaptation) + prevalence data obtainable - not easy to collect data (sensors) 12. Chalmers University of TechnologyGeneral FOT issues ethical issues (integrity, data access) legal issues (filming, data access) logistics issues (data collection, upload,back-up) analysis issues (retrievingrelevant info, data loss,statistics) 13.
