ATMS12-Roadside Lighting System Control (Service Package*)
This service package includes systems that manage electrical lighting systems by monitoring operational conditions and using the lighting controls to vary the amount of light provided along the roadside. These systems allow a center to control lights based on traffic conditions, time-of-day, and the occurrence of incidents. Such systems can increase the safety of a roadway segment by increasing lighting and conserve energy at times when conditions warrant a reduction in the amount of lighting.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.
The entire process is under the asynchronous monitoring (traffic operator data) and control (traffic operator inputs) of Traffic Operations Personnel. Operator input affects the control of the lighting system and status collected from the lighting system is reported to the operator.
The Traffic Management Subsystem remotely controls the operation of roadside lighting systems (lighting system control data), issuing requests for data, commands that alter locally stored configuration data, or commands that directly control the lighting equipment. Operational status of the lighting systems is monitored by the Traffic Management Subsystem (lighting system status).
