Study types

A study type specifies the means by which data can be gathered for analysis.  Each study type requires a specific list of parameters that the study will use to get collision records from the database. This section lists and describes each of the available study types and the .  


While a study has a few parameters that are used for data selection, that's just the first step.  After the data has been gathered from the database, the Crash Magic filter can be utilized to further limit the selected records.  So, you can select an intersection study and gather all the crash records that have matching primary and cross streets.  But from there, you can apply a simple filter to indicate that you are only interested in crashes that were within 100 feet of the intersection. You can even have the filter check to see if the crash was a rear-end collision, in which case 200 feet is acceptable.  The filters are extremely powerful and can be as complex you want to make them.


Note that many of the study types lend themselves to multi-purposing through the use of study templates.  So, for example, you may refer to each of your intersections with a "Facility Id", and you may be surprised to find that Crash Magic specifies "node" as the study type in your study template(s).   This flexibility enables Crash Magic to handle almost any sort of data and fields you have available.
