Description: This Signal Intersections layer was created in for use with the CityWorks work order and traffic data asset management system of Portland, Maine. Each Signal Intersection is designated by its main signal use including Traffic Signal, School Flasher, PedFlasher, Traffic Flasher, Parking Ban, Speed Monitor, or Lane Use. Each Signal Intersection has a unique ID and is linked to the unique ID of the main Control Box of the intersection. Additional data on attributes of Signal Intersections, such as Location, is included. Intersections were largely digitized based on the older GIS layer sde.PORTGIS.Traffic_Lights originally digitized by Michelle Sweeney in 2006 and updated byh Thea Youngs in 2016, in conjunction with Nasir Shir, and Kevin Thomas using staff knowledge and 2006 orthoimagery. These were updated by Briana Fischella in the summer of 2018 to current status with a combination of Streetscan imagery, 2015 orthoimagery, and field verification for older imagery and newer infrastructure not captured in most recent imagery. Ideally, these data will be updated through the CityWorks platform real-time as maintenance and servicing of assets occurs.
