Parking Violations Issued in March 2010

Parking citation locations in the District of Columbia. The Vision Zero data contained in this layer pertain to parking violations issued by the District of Columbia's Metropolitan Police Department (MPD) and partner agencies with the authority. For example, the District Department of Transportation's (DDOT) traffic control officers write parking violations to prevent congestion through enforcement and control at intersections. Parking violation locations are summarized ticket counts based on time of day, week of year, year, and category of violation. Data was originally extracted from the District Department of Motor Vehicle's eTIMS meter work order management system. Data was then loaded into the DC GIS, where the Office of the Chief Technology Officer (OCTO) geocoded citation data to the street segment level. Data are visualized using the street segment centroid coordinates.哥伦比亚特区停车罚单点位数据集。本图层所包含的零愿景（Vision Zero）数据，涵盖哥伦比亚特区大都会警察局（Metropolitan Police Department，MPD）及具备执法权限的合作机构开具的停车违章记录。例如，哥伦比亚特区交通运输局（District Department of Transportation，DDOT）的交通管控警员会通过在路口开展执法与管控，开具停车违章罚单以缓解路口拥堵。停车违章点位数据会根据每日时段、年度周次、年份及违章类别，对罚单开具数量进行汇总统计。该数据集最初提取自哥伦比亚特区机动车管理局的eTIMS计费工单管理系统，随后被导入DC GIS地理信息系统，由特区首席技术官办公室（Office of the Chief Technology Officer，OCTO）将罚单数据地理编码至街道路段层级。最终数据通过街道路段质心坐标实现可视化展示。
