A sample analysis of three of the sites is demonstrated in Figure~\ref{fig:selected-site}. This shows trajectory tracks projected in and with respect to the scene, mean speed and heading, and spatial distribution of motion-pattern-predicted collision point density with a interaction-instant $probability > 1e5$ and instantaneous $TTC < 1.5 seconds$.
Figure~\ref{fig:ttc_distro_sample} demonstrates
cross-sectional comparison of Constant Velocity TTC
distribution comparison across distributions for 20 merging zones for two
testable contributing factors,
each using all interaction-instant aggregation.
... In the first diagram, a cross-sectional comparison is made for merge zones situated nearer or further than 300 metres upstream from another intersection. When this distance exceeds 300 metres, the distribution mass appears to shift left except for a sharp increase in small TTC below 0.5 seconds. While this represents a smaller proportion of interactions, they are more "severe" measures of TTC (i.e. closer to zero). This comparison remains therefore inconclusive. In the second diagram, a cross-sectional comparison is made between merge zones with high approach traffic volume ratios and low approach traffic volume ratios, where $R$ is the flow ratio between approach volumes and total volumes at the merge zone. In this comparison, a clear and consistent mass shift is observed, suggesting that high approach traffic volume ratios contribute to safer merging behaviour in a roundabout.
