This Signals layer was created in order to establish a baseline for the CityWorks work order and traffic data asset management system of Portland, Maine. Each Signal is designated by its Feature Type including Traffic Signal, School Flasher, PedFlasher, Traffic Flasher, Parking Ban, Lane Use, Informational Signal, Speed Monitor and PedLight. Each Signal has a unique ID and is linked to the unique ID of its respective Intersection, Pole(s) and Controller. Additional data on attributes of Signals useful for maintenance and management is included. Signals were digitized 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. Also in the summer of 2018, fields and domains for all Signals 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 involving attributes of assets useful for management and maintenance are included for each Signal. Ideally, these data will be updated through the CityWorks platform real-time as maintenance and servicing of assets occurs. |
