Writing review & editing, Affiliation Over 44,000 California Highway Patrol traffic incidents involving animals between 2009 and 2020 were used to make the report. Secondly, they estimated the costs for species-specific WVCs for deer, elk, and moose-vehicle collisions (Alces alces). Since it was not possible to distinguish among the three injury categories when calculating the species-specific probabilities that a collision would result in a human injury, the relative frequency of each of the three injury categories was determined using the values in table 4. While the standard right-of-way fences are typically a barrier for large livestock species (e.g. Based on a review of the literature, the probability that a collision with a deer, elk, or moose would result in property damage, a human injury, and a human fatality was estimated. So Paulo State is home to approximately 44 million people, 21,6% of the total population in Brazil. This results in a mismatch; the required mitigation measures for wildlife do not adequately match the legal responsibility for animal-vehicle collisions, and the legal responsibilities regarding animal-vehicle collisions do not adequately meet biological conservation requirements. An estimated 12.2 percent were the result of collisions with horses (Equussp.) For example, in Sweden, ungulate-vehicle-collisions accounted for over 60% of all road accidents reported to the police during the 1990s [16]. The average cost for an animal-vehicle crash, regardless of whether human injuries and fatalities occurred, was R$ 21,656 (US $ 9,629). However, this percentage can be much higher in rural or natural areas with more abundant habitat and wildlife populations [14], [15]. We documented and explored the effects of animal-vehicle crashes on human safety in So Paulo State, Brazil. Competing interests: CMH was employed at the law firm Lazzarini Moretti Advogado during the time of study and did not receive any salary support. (72) The net return to the economy of British Columbia from hunting was estimated at Can$1,2707,450 for deer, Can$3,2503,290 for elk, and Can$1,2501,680 for moose. Most of the court cases (69.5%, n = 554) were related to animal-vehicle collisions on roads managed by toll road companies, whereas 30.1% (n = 240) were on state roads managed by DER, and only 0.4% (n = 3) on city roads. The traffic volume on toll roads is typically higher than on DER roads, and the posted legal speed limit usually varies between 80120 km/h [29]. The costs in table 4 are for all AVCs, regardless of the species, while the costs in table 5 relate to specific wildlife species. Motorcycles were most often involved with these fatal crashes (n = 94, 46.8% of all crashes with human fatalities). This is probably related to the relatively high traffic volume, high vehicle speed, and relatively high night-time use compared to DER roads. This type of liability does not suggest actual negligence or intent to harm on the part of the road administrators [41], rather, it is based on protecting the customer who is considered the more vulnerable of the two parties. resulted in human injuries, but the risk increased to 1823% for larger species such as moose (Alces americanus) [17]. and bovines (Bossp.). Interestingly, Brazilian law holds road managers responsible for animal-vehicle collisions. More than 95 percent of all AVCs result in property damage only (table 4), at an average cost over all collisions of $2,451. Supervision, This image provided by the California Highway Patrol, West Valley Division, shows a mountain lion found dead along Interstate 101 in Calabasas, Calif. Tens of thousands of mountain lions, bears, bighorn sheep, squirrels, birds and lizards have met their fate in collisions with vehicles across California in a study released by the Road Ecology Center at the University of California, Davis. A study that used data from nine states ( Colorado, Georgia, Minnesota, Missouri, North Carolina, Ohio, Pennsylvania, South Carolina, and Wisconsin) showed that 77 percent of these fatal accidents involved white-tailed deer. Western Transportation Institute, Montana State University, Bozeman, MT, United States of America, Roles However, airbags did not become mandatory for new vehicles in Brazil until 2014 [32]. (3) There were no similar data available for elk or moose. This number does not include hits that were not reported to law enforcement, and it has varied from about 2,000 to 4,000 each year. Writing review & editing, Affiliation Animals usually die immediately or shortly after having been hit by a vehicle. Additional human fatalities were allocated to the second smallest vehicle and so forth. table 4 the chances that a reported AVC results in a human fatality are based on GES data (table 8), while the chances for the cost estimates in this paragraph are based on a species-specific review of the literature. These carcass removal data were obtained by toll road maintenance personnel that checked the general road condition, including the potential presence of animal carcasses, at least once every three hours, on a daily basis. Funding: KMPMBF received the grant for the productivity fellowship #308503/2014-7 from Conselho Nacional de Pesquisa e Desenvolvimento Cientfico e Tecnolgico (CNPq). These types of collisions have increased substantially over the last few decades [11], [12]. Of the 797 court cases, 14.4% included human fatalities (n = 115 in total, mean = 11.5 per year). The average cost for an animal-vehicle crash without human injuries or fatalities (82% of the 23,415 animal-vehicle crashes) was almost 50% lower; R$ 11,364 (US $ 5,053), whereas the average cost for a crash with human injuries or fatalities (18% of the animal-vehicle crashes) was R$ 67,048 (US $ 29,813). In these select few cases, the judge ruled that the road administrator could not be held legally responsible for animals entering the road because these animal movements were fortuitous, and, as a consequence, animal-vehicle collisions could not necessarily be prevented, at least not along the entirety of the road network. Each crash is recorded only once; there is no possibility for duplicates for the crash records collected by the PMRSP. School of Forestry and Environmental Studies, Yale University, New Haven, CT, United States of America, Roles Examples of costs that are not easily quantifiable and that were excluded from these analyses are the costs associated with emotional distress of people involved in WVCs, the expenses involved with conservation efforts for threatened or endangered species, the costs of the distress of injured animals, the costs associated with the rehabilitation of injured animals, and the cost of cultural values impacted by wounded animals (e.g., native Americans or other groups in society). In general, the region has a tropical climate with seasonal differences in temperature and precipitation (2228 C on average; 14502050 mm precipitation annually) [24]. Of the 28,724 crashes, 71,62% (n = 20,575) occurred at night between the hours of 19:00h and 6:00h, with peaks around dawn and dusk (Fig 5). The total annual cost to society was estimated at R$ 56,550,642 (US $ 25,144,794). PLoS ONE 14(4): Based on the animal-vehicle crashes in the PMRSP database and the IPEA report Traffic Accidents along Brazilian Federal Roads: Characterization, Trends and Costs to Society [19], we calculated the costs associated with each of the reported animal-vehicle crashes between 20032013. No, Is the Subject Area "Livestock" applicable to this article? In addition, estimates were made of the amount of property damage (vehicle repair costs) as a result of a collision with these three species. This then suggests that road administrators are expected to fence the entire length of the road system. Our study demonstrates that the number of reported animal-vehicle crashes and associated costs are increasing in So Paulo State. Copyright: 2019 Abra et al. U.S. Department of Transportation Roles In addition, the decisions by the judges of TJSP were available in electronic format which allowed us to select and investigate a large number of cases. For more information about PLOS Subject Areas, click So Paulo State has one of the highest road densities in Brazil; 0.8 km roads/km2 (37,000 km paved roads and 163,000 unpaved roads) [26]. (72) In Pennsylvania, the average for deer carcass removal and disposal in a certified facility was $30.50 per deer for contractors and $52.46 per deer for the Pennsylvania Department of Transportation in 20032004 (Jon Fleming, Pennsylvania Department of Transportation, personal communication). Low income people in rural areas are known to abandon old or injured horses and dogs so that they do not have to deal with the financial expenses associated with veterinary care (Osnir Ormon Giacon, Concessionria CART, pers. This should ultimately result in a road system with improved human safety, reduced unnatural mortality for both domestic and wild animal species, safe crossing opportunities for wildlife, and reduced monetary costs to society. (15), The percentage of white-tailed deer-vehicle collisions resulting in human injuries was estimated at 1.3 percent in Finland; 3.8 percent in the U.S. Midwest; 4 percent in Ohio, 4 percent across the U.S., 7.7 percent in Ohio; and 9.7 percent in Nova Scotia. The weak seasonal pattern in animal-vehicle crashes in So Paulo State may also be due to the crash data from the Military Highway Police of So Paulo State which were based on a combination of domestic and wild species.

Formal analysis, If the animal has no owner, there is no responsible party, and thus no possibility for compensation [44]. Abandonment of domesticated animals including horses, cattle and dogs is more difficult to address. However, most of the costs (57%) were associated with crashes that involved human injuries or fatalities. Instead they refer to the 1st Instance of the Court of the State of So Paulo to calculate the amounts based on certain guidelines. For more reporting from the Associated Press, see below. In Canada, the clean-up, removal, and disposal costs for animal carcasses were estimated at Can$100 for deer, Can$350 for elk, and Can$350 for moose. En 10 ans, nous avons su nous imposer en tant que leader dans notre industrie et rpondre aux attentes de nos clients. , chapter 2), 20 percent in rural Alaska, and 23 percent in Anchorage, AK. The environmental licensing process can result in the requirement of mitigation measures aimed at reducing direct road mortality and providing safe crossing opportunities for wildlife. If there were multiple human injuries or fatalities, we allocated potential human fatalities and human injuries to the smallest vehicle type, up to the maximum number of occupants for that type of vehicle (see S3 Table). (72) From this information, an average value for recreational wildlife viewing per large mammal was estimated at Can$255. The crashes with human victims resulted in a yearly average of 531 humans with minor injuries, 116 humans with severe injuries, and 20 human fatalities. Though other courts in So Paulo State (e.g. Note the toll roads only covered 17.6% of the total road length covered by the PMRSP, 6,500 km of toll roads out of a total of 37,000 km of roads). No, Is the Subject Area "Domestic animals" applicable to this article? Though the total number of animal-vehicle crashes was similar for roads managed by toll road companies and DER, the number of animal-vehicle crashes with human injuries or fatalities on DER roads was more than double the number recorded along toll roads (Fig 3). Animal-vehicle crashes account for 45% of all reported crashes in the United States [13], [12]. It would take human safety, wildlife, as well as monetary costs into account. Property damage (repair costs for vehicles) has been estimated by a number of studies: Romin and Bissonette estimated the value at $1,200 ($1,881 for deer in Utah and Vermont) in 1992. For the analyses described above, 1994 USDOT estimates of motor vehicle accident costs were used, corrected for the Gross Domestic Product Deflator through the fourth quarter in 2006. The judge considered these animal movements to be fortuitous, and, as a consequence, the animal-vehicle collisions could not necessarily be prevented, at least not along the entirety of the road network. Each fall a group of organizations* come together to get the Wildlife on the Move message to motorists statewide: Be aware, drive with caution, and slow down, especially at night, when the majority of WVCs occur. The awarded amounts can consist of the following components: i) moral and mental suffering (impact on psychological, moral and intellectual mood, whether by offense to their honor, their privacy, intimacy, image, name or in their own physical body), ii) physical injuries and aesthetics (direct offense to the physical integrity of the human person), iii) material damage (damage caused to material property), and iv) loss of income (losses caused by the interruption of work and associated income). The costs in table 4 are for all AVCs, regardless of the species, while the cost estimates in this paragraph relate to specific wildlife species. In addition, we estimate the costs of these animal-vehicle crashes to society, and we summarize the legal perspectives with regard to liability and associated financial compensation for animal-vehicle collisions. Nonetheless, the requirements that result from the environmental licensing system, based on Environmental Impact Assessments or other instruments, are largely focused on biological conservation rather than human safety, and not on reducing collisions with large domestic species such as horses and cattle. (See references 68, 75, 76, 77, 78, and 79.) A total of 52% (n = 14,876) of the crashes were recorded on toll roads and 48% (n = 13,819) on state roads managed by DER. However, since animal-vehicle crashes have been increasing, the costs have likely been substantially higher in recent years. AVCs can cause human injuries. Note that air bags have been standard equipment in all new passenger cars in the United States since 1998. ), the yearly wildlife rehabilitation costs in Connecticut are estimated at $134,400179,200 (Laura Simon, Connecticut Wildlife Rehabilitators Association, personal communication). It is important to maintain control before, during and after a collision with an animal should one occur. The costs of human injuries by species type are $2,702 (deer), $5,403 (elk), and $10,807 (moose) for each collision. Currently, the land use in So Paulo State is dominated by agriculture (~59%mostly sugar cane, pastures, and eucalyptus plantations) and urban areas (~5%) [26]. We searched the TJSP database with the following Portuguese keywords: animal, acidente, rodovia and coliso and identified 2,261 court cases. The total annual costs to society associated with the reported animal-vehicle crashes in So Paulo State was R$ 56,550,642 (US $ 25,144,794 in 2013 [23]. Similarly, in Italy, the road administrator is held liable for wildlife-vehicle collisions [42], where the legal base is similar to Brazilian legal system. This may require different norms in society and a greater awareness of the potential consequences of abandoning animals, not only regarding animal welfare, but also with regard to human safety. Our study is a first step to specifically address human safety, economic and legal issues associated with animal-vehicle collisions in Brazil. While crashes with human injuries or fatalities only represented 18% of the animal-vehicle crashes, they accounted for the majority of the costs (57%). In Southern California, groundbreaking is expected next year for what would be one of the world's largest wildlife crossings, over U.S. 101 northwest of Los Angeles. Note that collisions with smaller animal species (smaller than deer) and domesticated species (e.g. For each court case we identified the total amount awarded by the court (if specified in the documents). In So Paulo State only 17,5% of the Atlantic Forest and the Brazilian Savanah remain [28]. In addition, cattle and horses often enter the road corridor because the right-of-way fences are not present or poorly maintained. Hunting license fees in British Columbia were Can$15125 for deer, Can$25200 for elk, and Can$25200 for moose, for residents and non-residents, respectively.
