The reliability and effectiveness of an electromagnetic animal detection and driver warning system
The reliability and effectiveness of an electromagnetic animal detection and driver warning system
This report contains data on the reliability and effectiveness of an animal detection system project along US Hwy 160 between Durango and Bayfield, Colorado. The system that was first installed was a Perimitrax® system from Senstar Corporation. In the fall of 2010 this system was replaced by an OmniTrax® system, manufactured by the same company, Senstar Corporation. The Perimitrax® system was also installed at a controlled access facility near Lewistown, Montana. Here more detailed investigations were conducted into the reliability of the system using horses, llamas and sheep as a model for wild ungulates. The number of reported large mammal carcasses and crashes with wild animals was highly variable and the number of years that data were available for after system installation in the fall of 2008 was low. Therefore it is difficult to draw conclusions about the potential effectiveness of the system on the number and severity of wildlife-vehicle collisions at this time., Description based on online resource; title from PDF cover; (viewed January 2013), "March 2012.", "Report No. CDOT-2012-2, Final Report.", Final Report.;, "Sponsored by the Colorado Department of Transportation in cooperation with the US Department of Transportation, Federal Highway Administration.", Includes bibliographical references (p. 56-57).

Tire-pavement and environmental traffic noise research study
Tire-pavement and environmental traffic noise research study
Following a rigid set of testing protocols, data is being collected on highway traffic noise characteristics along with safety and durability aspects of the associated pavements. This report completes a comprehensive, long-term study to determine if particular pavement surface types and/or textures can be used as quieter pavements, and possibly be used to help satisfy FHWA noise mitigation requirements., "Report No. CDOT-2012-5.", "June 2012.", Research performed by the Transtec Group, Inc., "Prepared in cooperation with the U.S. Department of Transportation Federal Highway Administration.", Includes bibliographical references (p. 22-25)., Mode of access: World Wide Web.
