摘要：	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. A total of 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. For the covering abstract and the URL of the conference see ITRD E205706.
