Availability and Current Use

ITS4mobility is available globally today and has been deployed in several Nordic cities.

Tromso, Norway provides travel information in real-time for 17 of its 100 buses using ITS4mobility, with plans to link the whole system.

In Gothenburg, Sweden, ITS4mobility tracks over 450 buses and trams, providing real-time passenger information to traffic controllers, information officers, to passengers at more than 140 at-stop displays, and also via the Internet and WAP. The on-board units will also be installed shortly on ferries operating in the public transport system of Gothenburg.

ITS4mobility can use any radio communications protocol, and can be installed for any size of fleet, Volvo claims.
