As in most big cities, the Stockholm metropolitan area suffers from excess of demand from road and street traffic. That creates problems for the environment, for general safety and for mobility efficiency. There is a need for an efficient distribution of traffic in the road network. However, part of the road network is a responsibility for the City, and part of the road network is a responsibility for the Swedish National Road Administration (SNRA). The City of Stockholm is a municipality, an entity which is independent of the Swedish national government. The SNRA is an administration under the government. An agreement has been signed between the City of Stockholm and the Swedish National Road Administration for establishing a joint traffic management centre, covering all national roads and all the City main streets in the Stockholm region. That means that the centre will cover both motorways and business streets with traffic signal systems. Other municipalities will join the centre, as well as the public transport authority and the traffic police.
