##### Traffic Estimation - Ticket Analysis

This method consists of collecting communication tickets in all the exchange centres in text files containing the following information:

- Location of the centre (header of the file);
- Collection time in days (header of the file);
- Origin of the call;
- Destination of the call;
- Time of the communication in minutes.

Once the files have been read by the system, the user has to assign to each possible origin/destination couple, a type of communication (urban, interurban, international outgoing, etc.).
If for any reason, the file is not available for a given location, the user has the possibility to copy the data from another location considered as similar.
The collection of the data must be performed in a "normal" period (avoiding, for instance, holiday periods) and the ideal duration would be five days.
If some files do not have the same collection time, the system will automatically normalize.
If the format of the data in the file is not correct, a message will be generated telling the user where the mistake is and asking him to correct the file manually.

#### Import text file

This button allows the user to import a new data file. When done, a data set number is automatically assigned and the “ticket interpretation” dialogue box is automatically started.

#### Import from another location

This button allows the user to import data from another location considered as similar, if the data file could not be extracted. The user has the possibility of selecting a data source from all the existing data sets in the system. The new location name must be entered manually, and a new data set number is automatically assigned by the system.
When done, the “location information” dialogue box is automatically started, as if the file had been normally imported.

#### Suppress data set

This button allows for suppression of an existing data set from the system. It will no longer be taken into account in the traffic estimation. A deleted data set cannot be recovered.

#### Ticket interpretation

This button allows for starting the “ticket interpretation” dialogue box that will allow assignment to each possible origin/destination couple, a type of communication (see dedicated contextual help or help file for more details).

#### Generate report

This last button allows for generation of a report that displays the content of all the data sets imported or copied, and for each line, the type of communication, if it has been defined by the user.
