Somewhat making a guess at what you're trying to accomplish: I think the InLineQuerier might give you what you want, with a SQL query something like:
SELECT COUNT(*) AS "Headon Loss Of Control", "CRA_ROUTE_" FROM "InputData" where "CRA_RUM_CO" in (20) GROUP BY "CRA_ROUTE_"; 
The results are a summary accident report :
I've also attached an FME Template file with your data and the workspace (FME 2017.1)
