It uses buses, trams and cable car to organize a transportation of students and also provides special transportation to people with disabilities.

Since the 1 of July 2006 ZET is a branch of the Zagreb Holding.
ZET, aside from its primary function, passenger transportation, in more than one century of its existence, greatly influenced the development of Zagreb, and this influence continues to grow by covering important day routes people take in Zagreb and suburban areas with its extensive tram and bus system. However, ZET continues to follow the city development and connects many newly built districts, and together with the City District Councils adapts the routes and stations to address the needs of citizens.
Thanks to financial support of the city and citizens of Zagreb many projects came through in the last couple of years which contributed to substantial progress in the development of public transit system. So far 70 new, modern, low-floor trams were purchased and the delivery of the second series which includes 70 low-floor trams is scheduled for March 2008.

Following the environmental standards, in the year 2007 ZET started to use biodiesel in public transportation vehicles, and from 2008. used compressed gas.
The radio connection system is modernized and traffic monitoring and control are also computerized by introducing vehicle location system. Setting up the infrastructure for 147 displays on tram and bus stations, on which passengers should be able to receive real-time arrival information, is in progress.
