Parking Violations Issued in September 2015

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。本图层所包含的零事故愿景（Vision Zero）数据，均来自哥伦比亚特区大都会警察局（Metropolitan Police Department, MPD）及具备法定执法权限的合作机构开具的停车违章罚单。例如，特区运输局（District Department of Transportation, DDOT）的交通管控人员会通过在交叉口开展执法管控以缓解拥堵，届时将开具停车违章罚单。该数据集基于单日时段、年度周次、年份及违章类别统计罚单数量并汇总停车违章点位信息。原始数据提取自特区机动车管理局（District Department of Motor Vehicle）的eTIMS计费器工单管理系统，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）将罚单数据地理编码至街道分段层级。最终数据通过街道分段的质心坐标实现可视化展示。
