Interestingly, our performance tests on offspring born in captivity showed that the progeny of older females were also slower (analysis based on mean speeds per litter, age: F1,30 = 8,18; P = 0.0078; size: F1,30 = 0.45, P = 0.5; interaction: F1,30 = 0.01, P = 0.9; Figure 3).
For the range of mean speeds typically found on 30 mph roads, the percentage accident reduction per 1mph speed reduction is around 4% for cameras and 7 8% for schemes with horizontal features.
On the other hand, the observed mean speed on the first post-sleep trial (26.6 sequences) was statistically indistinguishable from the corresponding theoretical speed (27.5 sequences; t(43) = −0.87, P≫0.1).
Results show that a 1% increase in mean speed on urban arterials was associated with a 0.7% increase in total crashes, and larger speed variation was also associated with increased crash frequency.
In contrast, the arthritic animals receiving indomethacin and NHAG treatments exhibited a significant reduction in the mean speed on day 20 (P < 0.02 for drug control and P < 0.001 for NHAG) possibly because of slight inflammation in their paw at the end of the experiment.
However, in a review of Graham et al. [ 20], only pace (fast or preferred gait speed) seems to have an influence on mean gait speed performance.
Previous studies on the variation of wind mean speed profile with inhomogeneous terrain usually assumed that wind speed profiles sense the roughness averaged in a large-scale terrain-grid, so terrain roughness patches of different distance to the site are regarded of equal importance.
Small size is advantageous in these movements because, for example, the mean speed achievable on vertical structures is indirectly proportional to body length (Moya-Laraño, Halaj & Wise, 2002).
Although the use of 1-second or 5-second analysis intervals had no meaningful effect on the distance covered or the mean speed reached, it did have a significant bearing on the detection of peak speed.
