Risk models can reduce number of collisions with wild animals

18.12.2003


Hundreds of thousands of animals are killed in traffic every year. The threat traffic represents to badgers is greater than was previously known. A new dissertation at the Swedish University of Agricultural Sciences (SLU) illuminates the conflict between traffic and animals in Sweden and provides models that predict the risk of accidents involving wild animals.



It is only in recent years that the impact of traffic on animal populations has been taken seriously. Today increasing traffic is regarded as a considerable threat to biological diversity in the world. In his dissertation, Andreas Seiler, Department of Conservation Biology, Grimsö Research Station, SLU, presents a new picture of traffic mortality among some common Swedish mammals.

For most animal populations in Sweden, traffic does not constitute a serious threat to the species, despite high numbers of traffic deaths per year. For badgers, on the other hand, the situation is different: estimates indicate that 12-13 percent of the Swedish badger population dies on Swedish roads every year. This is very close to the level that the population can bear, assuming that pressures from hunting and other mortality are constant. Andreas Seiler and his research colleagues therefore recommend that greater attention be paid to badgers in constructing and maintaining roads.


Following extensive research into the connections between traffic, density of wild animal populations, the make-up of the landscape, and the number of collisions between cars and deer and moose reported to the police, Andreas Seiler has developed models to predict the risk of moose accidents. He has made use of remote analysis, landscape maps, and statistics on traffic, roadways, and moose density (indicated by hunting harvests). The models show that lower speed is the single greatest contributing factor in bringing down the risk of accidents.

A combination of lower speed limits and fencing, possibly in combination with alternative passages for animals and increased distance to adjacent woods, seems to be the most effective measure to prevent moose collisions. Preventing collisions between vehicles and especially moose, but wild animals in general, requires a holistic approach that involves road construction, property owners, and drivers.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
