“…With our two stage approach participants were on average presented with only 18.35 conditions before a threshold was found. Our advanced method therefore allows researching a broader time headway range compared to the study by Gouy et al (2012Gouy et al ( , 2013 without increasing the number of experimental conditions. Results show that it is important to consider possible effects of the chosen variable for threshold detection, as the valence of the variable appears to influence ascending and descending sequences differently.…”

“…In this study we investigated the thresholds for subjective risk and comfort experience in car following. We used a refined version of the method of limits to determine time headway thresholds similar to the studies by Gouy et al (2012Gouy et al ( , 2013. Time headway was presented in ascending and descending sequences to locate participants' individual risk respectively comfort thresholds for different speeds.…”

“…Small Scale Descending Sequence: The experimental design of ascending and descending time headway sequences is similar to two studies by Gouy et al (2012Gouy et al ( , 2013, who varied time headway between 0.1 and 2.5 second, using ascending and descending 0.1 second steps. Each time headway step was presented for 5 seconds.…”

In this study the location of vehicle to vehicle distance thresholds for self-reported subjective risk and comfort was researched. Participants were presented with ascending and descending time headway sequences in a driving simulator. This so called method of limits of ascending and descending stimuli (Gouy, Diels, Reed, Stevens, & Burnett, 2012) was refined to efficiently determine individual thresholds for stable time headways with a granularity of 0.1 seconds. Time headway thresholds were researched for 50, 100, and 150 km/h in a city, rural, and highway setting. Furthermore, thresholds for self-driving (level 0 automation: NHTSA, 2013) were compared with thresholds for the experience of subjective risk and comfort in assisted driving, similar to adaptive cruise control (level 1 automation). Results show that preferred individual time headways vary between subjects. Within subjects however, time headway thresholds do not significantly differ for different speeds. Furthermore we found that there was no significant difference between time headways of self-driving and distanceassisted driving. The relevance of these findings for the development of adaptive cruise control systems, autonomous driving and driver behavior modelling is discussed.
