Parking Violations Issued in October 2017

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（District of Columbia）停车罚单点位数据集。本图层所包含的零愿景（Vision Zero）数据，均源自哥伦比亚特区大都会警察局（Metropolitan Police Department，MPD）及其他具备执法权限的合作机构开具的停车违章罚单。例如，哥伦比亚特区运输局（District Department of Transportation，DDOT）的交通管控人员会在交叉口开展执法管控，开具停车违章罚单以缓解交通拥堵。该数据集的停车违章点位信息，会依据当日时段、年度周次、年份以及违章类别对罚单数量进行汇总统计。数据最初提取自哥伦比亚特区机动车管理局（District Department of Motor Vehicles）的eTIMS停车计时器工单管理系统，随后被导入哥伦比亚特区地理信息系统（DC GIS），由特区首席技术官办公室（Office of the Chief Technology Officer，OCTO）将罚单数据进行地理编码，匹配至街道路段层级。最终采用街道路段质心坐标对数据进行可视化展示。
