Over the course of the winter, many a motorist may have noticed speed display signs in unexpected places, such as on Nokelantie Road in Oulu or near Alakylä in Kiiminki.
According to Jyrki Suorsa, a project manager at the Ramboll consulting engineering group, the speed display signs are being used in an engineering project to explore the effects of the signs on driving speeds.
Suorsa says that the idea was first brought up by the Oulu Traffic Safety Committee. The committee decided on a plan to continuously rotate the speed display signs around Oulu and neighboring municipalities, keeping the signs in one spot for about a week and later compiling the data.
”We’ve already been through Kempele, Haukipudas, Oulunsalo and Kiiminki,” lists Suorsa. “The overall aim is to find out whether utilizing this kind of speed display sign can reduce driving speeds, and if so, for how long”.
“It was recently decided that the display signs will be in use until early summer in the other municipalities in the Oulu area, including Hailuoto, a couple of weeks in each spot,” Suorsa adds.
