SITAC organizes your urban bus trips in Châlons-en-Champagne and its surrounding area. The network is made up of eight lines serving the ten villages around Châlons-en-Champagne and five peri-urban lines serving the other 28 municipalities.

To enjoy a bus ride, it's very easy as you have different options:
- Buy a single ticket from the bus driver
- Download the Sitac E-ticket application which allows you to buy one or more tickets (single ticket, modulo 12 trips or 24h ticket)
- Go to the SITAC agency located at Monseigneur Tissier square

The additional services offered by the SITAC:

- Flexo service:
The Flexo service, which runs from Châlons-en-Champagne train station or Monseigneur Tissier square, allows you to tell the driver which stop on the line you want to go to.

- ResaGo service
The ResaGO service allows you, by telephone reservation, to be picked up at a stop that would not be served without a reservation, and transported to a stop of your choice on the line concerned.

- TPMR service
In addition to the urban lines, people with reduced mobility are offered an adapted on-demand transport service available throughout Châlons Agglo.
