Data Column Descriptions

Here are all the columns in the results tables generated by the TOPS Lab. The columns that appear only in the HPMS-specfic format (see FHWA guide here for more detail) are indicated in red font.  Abbreviations used throughout include traffic message channel (TMC), national highway system (NHS), level of travel time reliability (LOTTR), truck travel time reliability (TTTR), and peak hour excessive delay (PHED), which is calculated anywhere posted speed limit and volume distributions are available (and officially reported for the Milwaukee adjusted urbanized area).
