The effect of newly installed Puffin crossings on collisions.

Webster, N.

This study looked at changes in collisions before and after implementation at 23 new stand-alone Puffin crossings grouped into 16 site groups. The Tanner test was performed, which combined the results from sites and compared any changes with borough control data for the same time periods. Over all sites, following the introduction of a Puffin crossing, there were reductions of 15% in total collisions and 26% in pedestrian collisions. These reductions were not statistically significant at the 0.05 level. When grouped by previous crossing facility, there were reductions in total and pedestrian collisions for nearly all site types. Therefore, there is no evidence that Puffin crossings pose a significantly greater risk to road users than other formal crossing types. However, where there had previously been no formal crossing, total collisions rose slightly but not statistically significantly. (Author/publisher)
