The TransisèreTransisère

Transisère, the transportation network operated by the General Council of Isère

  • It provides a unique zone fares for everyone in Isère;
  • A single visual identity for every player operating the network;
  • A network of points of sale on the whole area;
  • A more effective public transport solution.

 Several dozens of companies with their easily recognizable yellow and blue coaches operate the network under contract to the Department. Their mission is to operate one or several routes and maintain efficient public transportation services in the area.
Years after years, the public transport network expands, the transit network and the efficiency of provided services are increasing.
Thus, thanks to key bus and coach stations in Grenoble and Villefontaine, the network is equipped with high-quality services routes called “Lignes Express”. Apart from its outstanding frequency for an intercity route (one bus every 5 minutes during the morning peak time leaving from Voiron) the Ligne Express 1 Voiron-Grenoble-Lumbin is subject to tests that aim at improving its services quality. For instance, the implementation of a double decker coach was successfully tested in February 2011.
The General Council takes actions to improve the network regarding road transportation and infrastructure. Thus on September 3rd, 2010, a bus-only lane has been opened on the A48 highway in the direction going from Lyon to Grenoble between Saint-Egrève and Pont d'Oxford.
Since March 17th, the exclusive bus lane (XBL) extension has been built on 5 kilometres between Saint-Egrève dam and Veurey interchange. This XBL enables coaches to keep a good pace when car traffic is hampered. The extension is built by the company AREA, managing the project operation and maintenance.
The Department, still aiming at being as close as possible to the population, wishes to offer a unique service to liaise with. It has established a services manager combined with the network: Transisère Services. Among other things, this entity is responsible for the customer relationship management (Allo Transisère, the travel information helpline; the complaints department and so on).
Besides, a community manager maintains Facebook pages for Lignes Express 1, 2, 3 and 1920 to establish a customer dialogue updating news reports about the routes on daily bases.
In the future, efforts will be made to implement intermodality and complementarity between the different transport modes. In this perspective, Transisère network offers since April 1st 2011, the OÙRA! card. This contactless card enables users to travel on the entire Transisère network, Isère urban networks and TER trains with a single card. Besides, the General Council is working on developing new mobility services such as dynamic carpooling, car-sharing system, a multi-modal mobility hub or the Itinisère project.


Transisère in few numbers:

  • 1 000 vehicles
  • 4 789 stops daily served;
  • 385 local routes;
  • 95 routes connecting the department including 7 Lignes Express (express routes).
  • During winter, ski resorts are connected thanks to the Transaltitude services
  • This represents a budget of more than 76 million euros for the Transisère network.

Carbon footprint

When you use public transportation (171 kgeqCO2/, you may reduce up to 20% of your carbon emission compared to the use of your private vehicle.

Transport services: CO2 emissions display is mandatory since October 1st 2013. A decree published in the Journal Officiel (official bulletin giving details of laws and official announcements) in April 18th 2012, sets October 1st 2013 as the date from which public transports users have to be informed of the quantity of carbon dioxide emitted by the mode(s)of transport they use.

In order to favour the most eco-friendly mode of transport, the Grenelle II Act (the latest French environmental law) imposes on every transport provider (organizing the transportation of persons or goods) to inform users of the environmental impact assessment of their services.
