All Data

The all data study type is special in that it does not gather data for a specific geographic location.  The only parameter this study type accepts is a date range.  This makes the study useful for aggregated system-wide reporting such as high crash location lists, injury severity analysis, monthly trend analysis, etc.  In addition, the ad-hoc nature of this study type makes it useful for querying data for which a study type is not otherwise available.  Using the filter mechanism, the data returned from this query may be limited to a particular crash type, roads with a certain attribute, drivers with specific attributes, etc.  Creative use of filters within an all data study can even identify streets, intersections, zip codes or other geographic regions.

The parameters you'll need to provide for this study type are:

•Start date

•End date
