What makes an automated vehicle a good driver? Exploring lane change announcements in dense ...
summary
A fixed-base driving simulator study with N = 66 in Germany manipulates lateral offset (three levels including 0.75 m offset) and duration of lateral movement to test how a merging vehicle’s lane-change announcement reads to a lag driver. Main finding: medium offset with moderate duration rates highest on perceived cooperation; a fast 0.75 m move reads as aggressive and more critical. A new algorithm derived from these results outperforms a conventional human-behavior baseline in follow-up tests.
