Data Notes

This data was provided by PennDOT and will be updated annually, after PennDOT posts the new data. The data dictionary was updated on 6/10/16 to correct the coding for the Lane Closure Direction field. The 2015 data was updated on 6/23/16 to remove duplicate records. NOTE: The 2017 schema differs from all previous ones by the addition of two new fields: TOT_INJ_COUNT and SCHOOL_BUS_UNIT. Also, the source data stopped providing the ACCESS_CTRL and ADJ_RDWY_SEQ fields beginning with 2017 data and the LOCAL_ROAD field beginning with 2018 data. We are keeping these columns in the schema for the 2017/2018/future/cumulative tables for backward compatibility, but the values will all be nulls for the affected years. For the 2019 data, PennDOT stopped publishing MOD_INJ_COUNT (which we are keeping as a field, but the values will all be nulls) and MAJ_INJ_COUNT (which we are populating with the values from the new similar field SUSPECTED_SERIOUS).
