Important results from the project
The project’s objectives were largely achieved, as the data analysis identified locations with potential traffic safety risks. The narrow scope focusing on interactions between motorists and unprotected road users somewhat limited the method’s overall potential. With more time, it would have been valuable to further examine the relationships between braking, speeds, and accidents. The data indicated clear correlations, for example, between heavy braking and rear-end collisions on access roads
Expected long term effects
Hopefully the project will encourage road authorities to make greater use of data from connected vehicles, given the clear benefits such data provides across multiple areas. Beyond facilitating complementary traffic safety analyses, vehicle-generated data also holds considerable potential for supporting road maintenance and the management of transport infrastructure.
Approach and implementation
The project implementation followed the outlined activities. However, the schedule did not allow for a complete data collection before the site selection process began. Initially, this was not considered to have any significant impact. But, the volume of braking data increased substantially during the spring of 2025, which may have caused a different selection in one municipality. The project timeline was maintained, and the collaboration between the partners has overall functioned very well
