CTDOT Traffic Monitoring Data

A collection of layers maintained by the Traffic Monitoring Unit. The traffic signal control area polygons were developed by the CTDOT and updated by UConn and VHB. The feature class was developed by digitizing the area that represents the geographic extent of the signalized intersections. Attributes were migrated from the previous system and only the intersection number has been maintained. Long term plans are to remove some of the fields and migrate them to correct geographic asset in the signals data model. This will preserve the asset lifecycle.本数据集为交通监测部门（Traffic Monitoring Unit）维护的图层集合。交通信号控制区域多边形由CTDOT开发，并由UConn与VHB完成更新。该要素类（feature class）通过数字化表征信号控制交叉口地理范围的区域创建而成。其属性字段源自原有系统的迁移，仅保留了交叉口编号字段。长期规划将移除部分字段，并将相关信息迁移至信号数据模型中适配的正确地理资产位置，以此保障资产生命周期的延续性。
