The City of Minneapolis Traffic and Parking Services Division is currently performing a major upgrade to their Traffic Management Center (TMC) and traffic signals in order to cut commuter delays and reduce overall fuel consumption throughout the City.
The City’s TMC facility at 300 Border Avenue N. is being renovated to improve communications with all of its traffic signals and various other ITS devices throughout the City. The existing Fortran central traffic signal computer system and its associated communication hardware was installed in the 1970’s and system component replacement is no longer supported by the vendor.
Renovation of the TMC facility will feature the following:
- A new TACTICS central traffic signal control system, including the following:
- New servers for hosting the TACTICS software package
- A new video management system for viewing CCTV cameras
- A video wall system for staff to view and manage multiple cameras at a time
- Remote access to the traffic signal control system
- A new conference room with a ceiling mounted projector for viewing traffic signal system operations and other ITS devices
- 3 new workstation consoles for communicating with traffic signals, 15-55” LCD monitors, and new office furniture
- New air handling units for the conference room and the TMC facility and a revised computer server room
In the field, the City is performing traffic signal re-timing at nearly all of its signals in the City limits. This will be done in three general phases:
- Phase 1: The downtown Central Business District includes 204 traffic signals located in and around the downtown area. New timing plans will be implemented in July 2013 and fine-tuned in August 2013.
- Phase 2: The area south of downtown includes 342 traffic signals. New timing plans will be implemented in October 2013 and fine-tuned in late 2013 / early 2014. This area excludes the Hiawatha Avenue LRT traffic signals, which were recently improved in December 2012 as part of a project to better time traffic signals affected by LRT operations.
- Phase 3: The area north of downtown includes 232 traffic signals. New timing plans will be implemented in May 2014 and fine-tuned in June 2014. This area excludes the Central Corridor LRT traffic signals.
The City is also replacing 141 obsolete traffic signal controllers and cabinets. Approximately 19 are located in the north / northeast areas, 50 are located in the downtown area, and 72 are located in south Minneapolis. The City will also be collecting vehicle, bicycle and pedestrian counts, mass transit data, and other field data to establish new traffic signal timing plans.
When all the work is completed, the new traffic signal timing plans will be programmed into the traffic signal controller at each signalized intersection and integrated into the new central traffic signal computer system. Staff will then evaluate the new timing plans and make adjustments as necessary.
Approximately 80 percent of the funding for the Traffic Signal Timing Project comes from a federal Congestion Mitigation Air Quality grant. The remainder of the funding comes from various other sources.
