Many states are striving to keep their deer population to a sustainable and controllable level, while maximizing public safety. In Iowa, measures to control the deer population include annual deer hunts and special deer herd management plans in urban areas. While these plans may in effect reduce the deer population, traffic safety in these areas has not been fully assessed. Using deer population data from the Iowa Department of Natural Resources and data on deer-vehicle crashes and deer carcass removals from the Iowa Department of Transportation, we examine the relationship between deer-vehicle collisions, deer density, and land use in select urban deer management zones in Iowa. Further, we estimate models to investigate the factors that influence the frequency and severity of deer-vehicle crashes in these zones. The estimation results showed that multiple factors affect deer-vehicle crashes and corresponding injury outcomes in urban management zones. The identified roadway and non-roadway factors could be useful for identifying locations on the transportation system that significantly impact deer species and safety, and determining appropriate countermeasures for mitigation.
许多州都在努力将鹿的数量维持在可持续和可控的水平，同时最大限度地保证公众安全。在爱荷华州，控制鹿群数量的措施包括每年的狩猎和城市地区的特殊鹿群管理计划。尽管这些计划可能确实减少了鹿的数量，但这些地区的交通安全尚未得到充分评估。利用爱荷华州自然资源部的鹿群数据以及爱荷华州交通部的鹿与车辆碰撞和鹿尸清除数据，我们研究了爱荷华州选定的城市鹿管理区的鹿与车辆碰撞、鹿密度和土地利用之间的关系。此外，我们还建立了模型来调查影响这些区域鹿与车辆碰撞频率和严重程度的因素。估计结果表明，多个因素影响城市管理区的鹿与车辆碰撞以及相应的伤害结果。确定的道路和非道路因素可用于确定对运输系统中鹿种和安全有重大影响的位置，并确定适当的缓解对策。
