Title
Resolution authorizing and directing the Commissioner of Public Works to design an advanced street lighting control and monitoring system, and to design and implement a pilot project in a subarea of the street light system to deploy and operate the advanced system on a test basis.
Analysis
This resolution authorizes the Commissioner of Public Works to design an improved street lighting control and monitoring system utilizing the latest advancements in control system technology; to design communications systems improvements necessary to support the advanced control system; to extend the advanced communications system where practical to improve traffic signal system coordination; and to deploy and operate the advanced communication and control system in a subarea of the city on a test basis.
Body
Whereas, Street lights are currently turned on and off at over 250 substations and enclosures citywide, which in turn are operated by 10 separate electronic control circuits emanating from a centrally located master street light controller which utilizes a photocell to determine ambient light levels to control street light operation; and
Whereas, In the event of failure of all or a portion of an individual street lighting control circuit, street lights must be manually turned on or off at the substation or other enclosure once the failure is detected; and
Whereas, The operational status of street lights cannot be monitored from the central control location, and street lighting system failures are generally determined from citizen reports or complaints, or by street lighting personnel patrolling the city; and
Whereas, Technological advances in electronic control systems can provide for more efficient control of street lights, including turning street lights on and off by means of a photocell or astronomical clock, full-time monitoring of the status of street-lighting circuits and alarming in the event of circuit failures, monitoring power consumption on individual street lighting circuits, default time-based street light control at substations and enclosures in the event of system failure, and automated archiving of data related to overall system operation; and
Whereas, Capabilities of the advanced control system can provide for automated emergency backup control of street lights at substations and enclosures in the event of communication system failure, as well as the immediate detection of street lighting circuit failures, thereby improving response time to area wide street lighting outages, reducing the duration of these outages, and reducing the number of citizen reports and complaints relative to street light trouble; and
Whereas, Communication system infrastructure currently being deployed by the City can serve as the backbone for improved and more reliable communications systems necessary to support the advanced control system; and
Whereas, Communications systems installed to control street lighting circuitry can also be used to support and improve the reliability of synchronization of adjoining traffic signals; now, therefore, be it
Resolved, By the Common Council of the City of Milwaukee, that the Commissioner of Public Works is authorized and directed to undertake, or engage a consultant to undertake, the design and engineering of an advanced street lighting control system capable of the control, monitoring and archiving of data relative to the operation of street lights, and backup control and operation of local street lights in the event of control system failure; and, be it
Further Resolved, That engineering and design of the advanced street lighting control system include the development of the most reliable and cost effective communications system necessary to support the control system, utilizing to the extent practical the fiber optic-based communications system currently being deployed in the city; and, be it
Further Resolved, That communications facilities to be deployed in support of the advanced street lighting control system be capable of supporting anticipated future communications requirements for synchronization of traffic signals under the jurisdiction of the City; and, be it
Further Resolved, That a pilot advanced street lighting project be designed and implemented to deploy and test the above-mentioned system in a small subarea of the city; and, be it
Further Resolved, That the City Comptroller is authorized and directed to create within the Capital Improvement Fund, the necessary Project/Grant Chartfield values for this project, and to transfer to these accounts the amount required for this project and City Accounting Policy, but not to exceed a 10% increase in the total amount reserved for this project, or $5,000, whichever is greater as follows:
