Description

A traffic signal, also known as traffic light, is a signaling device positioned at a road intersection, pedestrian crossing, or other location that indicates which driver, rider, or walker is assigned the right–of–way at a given moment, using a universal color code (and a precise sequence for those who are color–blind)

Functional ObjectDescriptionUser Defined
Roadway Basic Surveillance'Roadway Basic Surveillance' monitors traffic conditions using fixed equipment such as loop detectors and CCTV cameras.False
Roadway Signal Control'Roadway Signal Control' includes the field elements that monitor and control signalized intersections. It includes the traffic signal controllers, detectors, conflict monitors, signal heads, and other ancillary equipment that supports traffic signal control. It also includes field masters, and equipment that supports communications with a central monitoring and/or control system, as applicable. The communications link supports upload and download of signal timings and other parameters and reporting of current intersection status. It represents the field equipment used in all levels of traffic signal control from basic actuated systems that operate on fixed timing plans through adaptive systems. It also supports all signalized intersection configurations, including those that accommodate pedestrians. In advanced, future implementations, environmental data may be monitored and used to support dilemma zone processing and other aspects of signal control that are sensitive to local environmental conditions.False
