This ControlBox layer was created for use with the CityWorks work order and traffic data asset management system of Portland, Maine. Each Control Box is designated by its Feature Type including Traffic Signal Controllers, School Flasher Controllers, PedFlasher Controllers, Traffic Flasher Controllers, Parking Ban Controllers, Speed Monitor Controllers, and Lane Use Controllers. Each Control Boxes has a unique ID and is linked to the unique ID of its respective intersection. Additional data on attributes of control boxes useful for maintenance and management is included. Control boxes were largely digitized based on the GIS layer sde.PORTGIS.TrafficLightControlBoxes originally digitized by Michelle Sweeney in 2006 and in updated by Thea Youngs in 2016, with assistance from Nasir Shir and Kevin Thomas in the summer of 2016 using staff knowledge and 2015 orthoimagery. These were updated by Briana Fischella in the summer of 2018 to current status with a combination of Streetscan imagery, 2015, 2017, and 2018 orthoimagery, and field verification for older imagery and newer infrastructure not captured in most recent imagery. In the summer of 2018, fields and domains for all Control Boxes were refined by multiple meetings and discussions with Scott Ouillette, Kevin Thomas, Thea Youngs, Kevin Deneault, Frank Mackie, and Jeremiah Bartlett based on maintenance and management needs of digitized traffic information. These data fields for attributes of assets useful for management and maintenance are included for each ControlBox. Ideally, these data will be updated through the CityWorks platform real-time as maintenance and servicing of assets occurs. |
