grouping 2 columns to see totals in pivot chart

Using Power Query which is called Get and Transform in your version of Excel, here is the Mcode to get the results shown in the attached file

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Crash Date", type date}, {"Crash", Int64.Type}, {"On System Flag", type text}, {"Crash Latitude", type number}, {"Crash Longitude", type text}, {"Crash Severity", type text}, {"Highway", type text}, {"Reported Street Name", type text}, {"Reported Road Block Number", type text}, {"Reported Intersecting Street Name", type text}, {"First Harmful Event", type text}, {"Manner of Collision", type text}, {"Object Struck", type text}, {"Weather Condition", type text}, {"Light Condition", type text}, {"Crash Contributing Factor List", type text}, {"CountA", Int64.Type}}),
    #"Removed Other Columns" = Table.SelectColumns(#"Changed Type",{"Crash Date", "Crash", "Reported Street Name", "Reported Intersecting Street Name"}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Removed Other Columns", {"Crash Date", "Crash"}, "Attribute", "Value"),
    #"Replaced Value" = Table.ReplaceValue(#"Unpivoted Other Columns","Reported Street Name","Main",Replacer.ReplaceText,{"Attribute", "Value"}),
    #"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","Reported Intersecting Street","Secondary",Replacer.ReplaceText,{"Attribute", "Value"}),
    #"Grouped Rows" = Table.Group(#"Replaced Value1", {"Value", "Attribute"}, {{"Count", each Table.RowCount(_), Int64.Type}}),
    #"Sorted Rows" = Table.Sort(#"Grouped Rows",{{"Value", Order.Ascending}})
in
    #"Sorted Rows"

Power Query is a free AddIn for Excel 2010 and 2013, and is built-in functionality from Excel 2016 onwards (where it is referred to as "Get & Transform Data").

It is a powerful yet simple way of getting, changing and using data from a broad variety of sources, creating steps which may be easily repeated and refreshed. I strongly recommend learning how to use Power Query - it's among the most powerful functionalities of Excel.
