Description: The dataset contains the location and attributes of traffic signals in the District of Columbia. Attributes are aggregated to the controller level (ACISA), where a single controller directs one or more traffic signals at one intersection or clustered intersections. The following attributes of signalized intersections are tracked: leading pedestrian intervals (LPIs), No Turn on Red (NTOR) signage, all-pedestrian phases, bike phases, queue jumps, transit signal priority (TSP), pedestrian recall mode, HAWK/PHB signals, and accessible pedestrian signals (APS).This data is updated periodically and may not be current at the time of viewing. More information on safety features implemented at traffic signals can be found here: https://visionzero.dc.gov/pages/engineering.
