      Process Step:
        Process Description:
          Data originated from the TRansportation Information and Planning Support (TRIPS) mainframe database which in turn then feeds into a sequel database which offers greater flexibility in reporting. The information is then extracted using the tool Hyperion and exported into the Excel format.

      Process Step:
        Process Description:
          The excel spreadsheet was imported into a personal geodatabase. From the personal geodatabase, route events were created for the corresponding routes. (Due to the nature of the Vertical Curve, route events were placed on the Increasing LRS using the BegARM.) Route events were exported into feature classes and merged into one data set. If errors, error messages were reviewed. An EVENTERR column was added, 0 = No Error and 1 = Error.
