From the Rural ITS Toolbox report: Subsection 7.4 Animal Warning Systems
An Animal Warning System has been deployed in the Greater Yellowstone Rural Intelligent Transportation Systems (GYRITS) corridor. A transmitter is installed along the road where a high number of animal-vehicle incidents have occurred. The transmitter has a range of 1-mile in each direction. When an animal is detected, the transmitter sends a signal that is received by an in-vehicle radar unit. The estimated cost for the system is $3,800 and includes one transmitter, one solar pack, and installation. The cost does not include off-the-shelf in-vehicle radar detectors required to receive the signal from the transmitter.
System cost: $3,800 per site.
