HLJ 2015

The Helsinki Region Transport System Plan (HLJ 2015) defines the transport system development needs and sets out the most important development measures well into the future. The preparation of the plan was closely linked to the Helsinki Region Land Use, Housing and Transport cooperation (MAL) and regional land use planning.

The goals of HLJ 2015 emphasize the accessibility of the region, flow of traffic as well as social, economic and ecological sustainability.

The following five policy statements summarize the contents of HLJ 2015:
- The funding of the transport system is strengthened
- The service level of sustainable modes of transport is improved
- Information and steering tools are eff ectively utilized
- The needs of logistics and flow of road traffi c are catered to
- Results are achieved by effective methods.

Impact assessment

Impact assessment was a fundamental part of the preparation of HLJ 2015. It supports the planning, interaction and decision-making. The impact assessment of HLJ must meet the requirements of the Act on the Assessment of the Impacts of the Authorities’ Plans and Programmes on the Environment (SOVA).

HLJ Committee

The transport system plan was prepared under the direction of HSL’s HLJ Committee.


Traffic surveys and forecasts

Traffic surveys and traffic forecast models are important tools in transport system planning.

The surveys provide extensive observation data that is then used to produce basic key figures for the movement of people and goods. The key figures include, for example, total numbers of journeys and goods deliveries as well as the modal shares of the different modes of transport in the region.

The data is also used for traffic forecast models. Traffic forecast models are needed for the assessment of the impacts of land use and transport system development on traffic, for example, for predicting changes in traffic volumes and their impacts in different points of the transport network.

The Extensive Traffic Survey conducted in 2007-2008 produced basic data on the movement of people in the Helsinki region commuting area. The data was used for producing the key figures and forecasts needed. In 2012-2013, the traffic survey dealing with passenger transport was updated in the 14 Helsinki region municipalities, and representative data was collected on goods transport. The most geographically central parts of the traffic forecast models were updated on the basis of the new data.

The series of surveys consist of the following sub-studies:

  • Traffic Survey in a smaller area than in 2007-2008
  • HLJ barometer: the survey seeks residents’ views on the transport system development goals and measures.
  • Delivery traffic GPS study: the study examines delivery traffic characteristics and the performance of the transport system from the point of view of delivery traffic
  • Logistics area study: the study seeks to establish freight traffic volumes, composition and distribution in the key logistics areas and harbors in the region.

Accessibility studies (SAVU)

The accessibility studies describe regional accessibility by public transport, walking and cycling. The studies allow us to identify the best land use development areas in terms of sustainable modes of transport.
