Description
This involves the installation of warning systems for the prevention of accidents involving deer at known deer crossing points. A network of infrared sensors covers both sides of the road to a distance of around 300 m. If an animal enters this area, it is detected by the sensors. These send an impulse to a traffic warning signal which lights up and warns approaching drivers of the immediate danger.

Impact
|
|
Impact in particular on
|
Big mammals
|
|
Ecological impact
|
|
|
Reduction of fragmentation or creation of new valuable habitats
|
Does not mitigate the barrier effect of a road. However, it is a very effective method of reducing the number of accidents involving deer at hazard hot-spots. |
|
Other
|
The system aims to change the behaviour of car-drivers, not deer. Drivers are alerted to an acute, rather than a potential, hazard. |
|
Time of realisation for measure
|
Immediate:
Impact starts as soon as the system comes into operation.
|
|
Impact scope
|
Very localised (plot):
This measure has a very localised impact on both sides of a section of road to a distance of around 300 m. If integrated into regionally significant wildlife corridors, however, it can also have impacts beyond the immediate locality.
|
Implementation
|
|
Implementation period
|
Days:
The system can be installed quickly once a decision has been taken on where it should be located (in consultation with hunters).
|
|
Frequency
|
Recurring:
Long-term measures, to be adapted as required.
|
Economic and legal aspects
|
|
Costs
|
Medium (10'000-100'000 EUR):
Costs of this type of system amount to approx. € 60,000-100,000. More compact and flexible solutions are also available (e.g. mobile systems).
|
|
Socio-economic impacts
|
Medium:
Prevents damage to vehicles, physical injury to individuals and loss of game animals.

Sources of financing

Public: local,
Public: regional,
Public: national,
Public: European

|
Legal situation
|
Voluntary cooperation among stakeholders. |

Evaluation
|
A pilot project involving Calstrom-type warning systems carried out from 1995-1997 in Switzerland had very positive effects. |
