Using transport telematics in preventing animal accidents
2001 (English)Report (Other (popular science, discussion, etc.))
Abstract [sv]

Finland has six species of animals in the deer family. The most significant

from the standpoint of road safety are the elk (Alces alces), the

white-tailed deer (Odocoileus virginianus) and the reindeer (Rangifer

tarandus). Because of its weight and size, the elk, in particular, is a

significant cause of accidents. The number and cost of elk and deer accidents

have risen again throughout Finland after a slight drop in the beginning of

the 1990's. Finnra has conducted a survey in which several concentration

points of elk accidents on the road network of Uusimaa region were

identified. Finnra has traditionally averted animal accidents mainly by using

warning signs to warn drivers about animals, by clearing roadside vegetation

to improve visibility and by building game fences along roads. With the help

of transport telematics special road safety measures can be arranged at elk

crossing points. The risk for accidents can be kept low by designing the

crossing points well. The sites for the openings in the elk fence must have

especially good visibility from both directions of road. Automatically

variable elk warning signs were built on highway 7 in Uusimaa region. 1 650

metres long new elk fence was built along highway 7 in 1996 and the new

"door" for passing elk was opened. The detection system observes large

animals by the sides of the road. The signs on highway 7 turn on whenever

sensors detect an approaching animal. Static warning signs are placed 500

metres and variable fibre optic message signs 200 metres before the "door" on

both sides of the carriageway. "The door" was about 200 metres wide opening

in the elk fence. Totally 20 microwave detectors were installed on both sides

of the road on five poles on each side. There is also a video camera and

recorder in the system, which starts when the alarm system is on. To monitor

traffic volume and speeds there are inductive loop detectors on the road in

the middle of the "door". The paper presents the results from a study

concerning measurements in two winter months and two summer months.
