The file, "Evidence_for_Traffic_at_Pompeii", is a spreadsheet containing the description of 1024 curbstones, guard stones, and stepping-stones, upon which the evidence for ancient traffic at Pompeii were inscribed. These data underlie and support the tables, figures, and arguments of Poehler, Eric. E. 2017 The Traffic System of Pompeii. (New York: Oxford University Press) and should be used in consultation with that work. Using tabs in the spreadsheet, these data are combined as a single table (Traffic_Evidence_All) and also divided into each object type. Field names are intended to be both human readable and in formats ready for use in other software environments. Copies of these data in more sustainable formats, such as .csv and .txt, are appended as additional files, but include only the combined data table.
