Planning and construction
Transport and traffic planning in Helsinki embraces all modes of transport: public transport, cars, cycling and walking. There is a special emphasis on public transport to ensure smooth and high-quality service. Traffic safety is the key goal in all transport and traffic planning.
From city plan to street plan
Major transport and traffic solutions, including main streets and rail lines, are defined in the city plan and partial city plans.
More specific transport and traffic arrangements are defined in traffic plans prepared with detailed plans. Transport and traffic plans define how streets are divided among different transport modes (cars, trams, pedestrians, cyclists, etc.), the number of lanes and parking.
A smaller arrangement, for example, conversion of a junction to a roundabout, can be made on the basis of a transport and traffic plan alone without revising the detailed plan.
Street plans are made on the basis of transport and traffic plans. Street plans define street dimensions, elevation, pavement materials, plants, lighting and draining solutions.
Transport and traffic plans are made by the City Planning Department’s Transport and Traffic Planning Division, and they are approved by the City Planning Committee. The smallest arrangements, such as street bumps, are approved by the Director of the Transport and Traffic Planning Division.
Street plans are made by the Public Works Department, which is also responsible for street construction.
Street plans are approved by the Public Works Committee.
In case of large implementation costs for transport and traffic plans, the plans are approved by the City Board and City Council.
The street network is improved on the basis of initiatives and feedback from residents and organizations. Feedback can be submitted through the City feedback system. Initiatives are sent to the City Register Office.
Anyone can participate in transport and traffic planning by giving feedback on plans under preparation. Information on current plans is published on the Internet, in newspapers and by mail to the parties concerned.
