Parking Violations Issued in April 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.本数据集为哥伦比亚特区（District of Columbia）停车罚单点位数据。该图层所包含的零愿景（Vision Zero）相关数据，涵盖由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）的交通管制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。停车违章点位数据会根据当日时段、年度周次、统计年份及违章类别，对罚单数量进行汇总统计。该数据集最初提取自哥伦比亚特区机动车辆管理局（District Department of Motor Vehicle）的eTIMS停车咪表工单管理系统，随后被导入哥伦比亚特区地理信息系统（DC GIS），由哥伦比亚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。最终数据集通过街道路段的质心坐标完成可视化呈现。
