In recent years Zagreb has experienced a drastic growth in the level of motorisation. This has had a huge impact on the environment and the traffic situation. The large number of personal cars in the city centre is result of an insufficient road network in the northern part of the city, thus requiring all vehicles to travel across the city centre to go from east to west. There is also an inadequate level of public transport with an insufficient number of vehicles and an ill equipped management system.
The study proposes modalities for introducing congestion charging in the city centre, and defining the exact target area. It also familiarised the public with the possible positive results of such a measure, thus ensuring their support for its implementation. There was also a focus on mitigating the impact of private and transport vehicles on the city environment and finding the most appropriate instruments to achieve its purpose.
