Parking Violations Issued in December 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.本数据集涵盖哥伦比亚特区（District of Columbia）的停车罚单点位信息。本图层包含的零愿景（Vision Zero）数据，涉及由哥伦比亚特区大都会警察局（Metropolitan Police Department，缩写MPD）及其他具备执法权限的合作机构开具的停车违规罚单。例如，哥伦比亚特区交通运输局（District Department of Transportation，缩写DDOT）的交通管制人员会在交叉口开展执法管控以缓解拥堵，期间开具停车违规罚单。停车违规点位数据按照当日时段、年度周次、年份及违规类别，对罚单发放数量进行汇总统计。该数据集最初从哥伦比亚特区机动车辆管理局的eTIMS咪表工单管理系统中提取。随后数据被导入哥伦比亚特区地理信息系统（DC GIS），由首席技术官办公室（Office of the Chief Technology Officer，缩写OCTO）将罚单数据进行地理编码至街道段层级。数据集采用街道段质心坐标进行可视化展示。
