-The database seems to be well-organized. The information it contains is significant to and relevant many kinds and directions of analysis. The database has a good structure, too. The data is divided into three tables: One containing information on the CRASH (its occurrence), the VEHICLES involved, and the PERSONS involved. +The information contained is significant to and relevant many kinds and directions of analysis.

 What the data does a poor job at is accommodating the inherent differences in a crash with a bicyclist. Bicycles do not appear in the data as vehicles; instead of noting whether or not bicyclists carried legally-required lighting devices, it notes if they were wearing "contrasting clothing." The data does not include dooring (although this will change for 2011 data).  What the data does a poor job at is accommodating the inherent differences in a crash with a bicyclist.
