Create your first study

Top  Previous  Next

In order to generate a report, you must first decide on the data you would like the report to display. Perhaps you are looking for all the crashes at a particular intersection for the past year.  Or, you might be looking for the crashes that occurred on a particular stretch of highway.  Depending on how you would like to gather your data, you select a particular "study type".   Start by clicking on the "New study" button above the project tree.

 

Note about available study types: Crash Magic supports many types of studies. Your installation of the software has been customized to show templates for studies that can be supported by your data.  For example, as a local agency with no rural roadways, you may not have a "milepost" field.  In that case, your configuration will not include a "route milepost" study template.  However, you are likely to have an "Intersection" or "Node" study template.

 

Note about using your own safety management system to gather data: In some agencies, the data selection is done by your own in-house system.  Your safety management system has a link, or button that you can click on to "send" the data to Crash Magic.  In this case, you will not click on a study template button for this tutorial step, but rather, you should now log into your safety management system and request that it send a selection of crashes to Crash Magic.  Please see your internal documentation for more information on this step.  Depending on how your system was written, you may jump to the end of this step, or all the way to a new diagram or chart.

 

The study settings panel will be displayed for you to select your desired study type and pick criteria for it to use while gathering data. For example, an intersection study will require a date range and two street names.  A route milepost study will require a date range, route name and starting and ending milepost. Choose an intersection, node or route-milepost section with a sampling of crashes available.

 

Depending on your choice of study type, you will now be presented with several properties to fill in such as street names, dates, etc. Fill in those properties.

 

You'll notice that the page you are on contains several tabs.  The one you are currently working in is the green settings tab. Click the "Study information" tab.  You will now be presented with a report showing you some basic information about the data you have selected.

If you've got values (other than 0) in your record count fields, you're good to go.  If not, return to the green settings tab and change the criteria so that the study contains data.  (i.e. different dates, streets, id's, routes, etc.)  A common problem is a time period without data. If you've got settings for dates available, be sure to include a valid date range.

 

For the purposes of this tutorial, it is best to have a query with 5 to 75 crashes in it.
