Filtering by TMC Tables
A customer profile includes a set of TMC tables, which specify the traffic data that you can request from the service. Requests that use TMC tables follow the same pattern as requests for traffic flow tile overlays, but differ in terms of parameters.
For a list of sample TMC codes, see Traffic Coverage.
You can include or exclude certain tables in your profile via the
tables parameter in the request, paired with the TMC code (see also TMCCodeType). Positive values for the TMC code specify which tables are to be included, and negative values specify tables to exclude. You cannot combine a positive and negative value in a request: such a request is not support an results in an error.
