Bonj gives us some occassional updates on the IT consolidation efforts in Missouri. I looks like right now, one of the major discussion items is the shared use of Missouri DOT's dark fiber. DOT's around the country are putting in fiber networks to support the development of intelligent transportation systems (ITS).
Massachussetts is using the ITS fiber to provide internet service in underserved areas of the state and enhance regional competitiveness.
Fort Bragg is anticipating savings of $50,000 a month through the implementation of a fiber based control network for their energy management system.
An article in ITS world states that the fiber in Salt Lake Valley was installed at a cost of $51 million, but the ATMS (advanced traffic management system) has an annual benefit of $179 million. That sounds pretty significant. Another article provides details about the system:
"...the ATMS provides instrumentation on 70 miles (112 km) of area freeways. The system includes closed circuit TV (CCTV) camera coverage every 3,300 ft (1,000 m), traffic monitoring systems that entail embedded loop detectors and microloops approximately every 2,640 ft (800 m), 31 variable message signs (VMS) located on the freeway, four weigh-in-motion stations on the I-15 corridor, seven roadway weather information stations (RWIS), and a fully redundant, self-healing fiber optic backbone communications system."
Costs and other information are found in the 2004-2008 Wasatch Front STIP.
There are some interesting comparison's with San Antonio's system. Here's a look at their current data.
