ITS Botnia

The iRoad project addresses both research challenges and industrial needs. Test sites are used to acquire the necessary data for research and to test concepts and prototypes in a real-life setting. Currently, tests are conducted in Northern Sweden (public roads in the Luleå-Piteå region) and there are three primary test sites:

  • E4 at Rosvik

    The test site is actively used since the very beginning of the iRoad project. Currently, a road strip of approximately 1.5 km is in use, where a two lane road merges into a one lane road just before the intersection "Rosvik north". The installation is in the south-going direction, but is partially visible when travelling towards Luleå.

    The main objective of this test site is to test physical installation properties and the resilience of the road marking units towards snow plowing and heavy traffic. For example, during one winter several hundred plowing events can occur. The road marking units should tolerate these events and operate without malfunction.

  • Road 94 close to Alvik

    Another test site is the rural road 94 towards Älvsbyn. Intelligent road studs are installed on the center lane marking prior to the bridge over Aleån River. To enhance visibility of the narrowing driving lane road studs are mounted on same lateral position as the left and right lane markings along the bridge.

    The main objective of the installation is to study the effect of the improved visibility of the lanes on the perceived safety of the road users. This is of special interest when vehicles pass over a narrow bridge while there is oncoming traffic in the opposed lane.

  • LTU Roundabout in Luleå

    The latest test site is the LTU roundabout close to the Luleå campus of Luleå University of Technology. The primary objective of this test site is to collect data, to test the technology platform (hardware and software) and to analyze the performance of distributed functions created by a wireless sensor network. This means that the road marking units communicate with each other, a road side unit, other parts of the infrastructure, vehicles and road users.

    The current feature is a traffic triggered running light that informs approaching road user on the upcoming roundabout and the traffic direction in the roundabout. This application involves detection of vehicles that are either in the roundabout or are about to enter the roundabout, and subsequent coordinated actuation of the distributed wireless road studs. It is important to note, that the test site is active even if the installation is not interacting with road users.

Demonstrators are also used to present the current achievements and involve the general public into research activities.
