Traffic lights

Our traffic light service is responsible for the traffic light control of all the highways in Finland. The traffic light service plans, implements and maintains the traffic lights of highways and the related operating and control systems and data communications in a reliable manner with affordable life-cycle costs.

Planning and construction according to the traffic environment

Our planning work is always based on the best possible efficiency of physical and functional solutions. The functional level of quality determines our choices and solutions from the preliminary and general planning phase.

In the actual construction planning phase, we prepare a plan report, drawings, work-specific quality requirements, work specifications, traffic light timing forms, the type drawings to be complied with and cost estimates.

In the implementation phase, we take full responsibility for the measures taken during construction from contractor tendering to work supervision and testing. We are also responsible for the deployment of equipment and systems, including the related user and maintenance training and final documentation. 

The roles and responsibilities related to planning and implementation are always agreed and specified on a project-specific basis.
