Book Description
Animal-vehicle collisions are a growing concern in terms of human safety; costs related to injury, property damage, and disposal; and the viability of wildlife populations. These collisions are rapidly increasing throughout the United States, and Virginia is consistently ranked among the states with the highest number of deer-vehicle collisions, in particular. Federal and state agencies have consequently placed added pressure on transportation departments to implement measures to reduce these incidents. It is often unclear to transportation practitioners, however, which mitigation measures are effective and where, how, and under what circumstances to use a measure for a particular road project. Although determining a definitive solution for any particular situation is difficult, the toolkit developed in this study is intended as a "quick" guide to provide information on the latest research available on the effectiveness of various mitigation measures to reduce animal-vehicle collisions. More extensive information on one particularly effective technique, wildlife crossings, is provided to assist in implementation and design decisions.

Book Description
This report reviews 39 mitigation measures that reduce animal vehicle collisions and that provide habitat connectivity for wildlife across highways. The overview is restricted to mitigation measures aimed at large terrestrial mammals (deer size and larger). However, this report also includes information regarding how such measures may affect or benefit federally endangered or threatened species in Montana, regardless of their size. In addition to the detailed information for each mitigation measure, a summary table is provided that provides at a glance information on the costs and benefits of the individual mitigation measures for which such data were available. Furthermore, the report graphically illustrates which measures have the best monetary balance (the difference between benefits and costs) and which measures reduce animal vehicle collisions and associated costs best. Based on the results, the authors of this report identified wildlife fencing, with or without wildlife underpasses or a combination of wildlife underpasses and overpasses, and animal detection systems with wildlife fencing, as the most cost effective mitigation measures. Animal detection systems without wildlife fences or wildlife fences with a high density of wildlife overpasses are also cost effective, but more data on system effectiveness are needed before these systems are recommended for implementation rather than further study. The final section of the report provides suggestions on the implementation or study for each of the 39 mitigation measures.

Book Description
Animal-vehicle collisions (AVCs) have a growing impact in the United States in terms of safety, economic loss, and species conservation. According to estimates from insurance claims, Virginia has consistently ranked as one of the top seven states for deer-vehicle collisions (DVCs) since 2002. Of the state's estimated 43,500 to 47,700 DVCs in 2006, less than 14% were reported to the police and stored in the Virginia Department of Transportation's (VDOT) accident database. Virginia has no standardized method of sufficiently tracking AVC occurrences and locations, creating difficulty in researching and implementing mitigation efforts to reduce accidents. Valuable AVC data can be obtained from documenting the instances and locations of animal carcasses from the roadway, but most transportation organizations do not systematically record these removals. This project entailed testing a personal data assistant (PDA) enabled with a global positioning system (GPS) receiver for the collection and analyses of animal carcass removals (CRs) from the roadway. Using GPS-enabled PDAs and software developed by Western Transportation Institute, maintenance personnel from a VDOT area headquarters in Rockbridge County collected 8 months of spatially accurate CR data. Rockbridge County DVC estimates derived from the CR data collected for this study were more than 9 times greater than the number of AVCs reported in police records. These spatial data can be easily used for density analyses to determine "hotspots" of AVCs. Implementing mitigation at these areas can ultimately lead to fewer AVCs and associated reductions of human deaths, injuries, and financial losses; improved traffic operations; a reduction in maintenance costs related to carcass removal and disposal; and wildlife conservation. VDOT is currently undergoing changes to its method of documenting roadway maintenance activities, including the deployment of GPS-enabled PDAs to all area headquarters. These PDAs provide a mechanism for collecting spatially accurate and standardized CR data, but collecting and reporting CRs are currently not requirements. Given the PDA's ease of use and the benefits these data would provide, the study recommends that this procedure be integrated into regular practice by VDOT area headquarters. As VDOT is receiving added regulatory pressure to implement measures to reduce AVCs, improving CR data collection using the technology described in this report can help provide an objective method for deciding whether and where mitigation is needed.

Book Description
This toolbox contains what is believed to be the most detailed summary and evaluation of DVC countermeasure information. Three levels of discussion are provided that focus on the current state-of-the knowledge countermeasure related to 16 potential DVC countermeasures and specific findings and conclusions for each countermeasure are discussed.

Book Description
In all western states, domestic animal and wildlife populations are increasing as well as the vehicular traffic volumes. Consequently, increases in animal-vehicle collisions have been reported by many states. The purpose of this report is to provide a synthesis of animal-vehicle collision mitigation measures utilized by other states and to provide a cost-effective recommendation for ADOT to further reduce animal-vehicle collisions. Preparation for this report included assembling documented studies currently underway and existing reports, and conducting a survey among selected states and countries to learn what practices have been used for solving or alleviating animal-vehicle collisions.

Book Description
As important habitats are being lost to human development, transportation agencies are facing increased expectations that their road projects avoid or minimize further habitat destruction and adverse effects on wildlife populations. Wildlife linkage or landscape corridor analyses are being conducted in an increasing number of states, and more transportation agencies are using this information during the planning of proposed road projects. The Virginia Department of Conservation and Recreation's Natural Heritage Program is creating a GIS tool, the Virginia Natural Landscape Assessment (VANLA), that identifies large patches of natural land cover (habitat cores) and the habitat linkages connecting these areas (landscape corridors). This analysis can be integrated into the Virginia Department of Transportation's (VDOT) existing GIS applications for access by staff involved with transportation planning and environmental scoping activities. Analyzing a proposed project in the early stages of project development would allow VDOT to identify important natural resource areas and habitat corridors to avoid or for which mitigation may be appropriate or necessary. This can result in fewer project delays, promote collaboration between VDOT and state natural resource and regulatory agencies, and meet the directives of the new habitat conservation provision in SAFETEA-LU, the federal transportation legislation. In addition, basing particular project decisions on a project's location relative to a habitat corridor can decrease the risk of costly animal-vehicle collisions.
