77 their positioning is not the most accurate available. Note that there is only one clearly corrupt track in the set, and this is screened out in the next stage, which is to apply the KF to the 367 cases and use speeds and distances to calculate TTC time histories.

78 was 1.4 s. There is a clear pattern of conflict frequencies increasing roughly linearly with increasing TTC value.
