researchers at NEC have shown it is possible to monitor traffic using “lit” fiber after separating out sensor and telecom data. Giovanni Milione of NEC Laboratories America, and colleagues used such fiber in Dallas and New Jersey to record the speed of cars as accurately as can be done with cameras
DAS converts a standard single mode telecoms fiber optic cable into an array of distributed sensors to deliver spatially and temporally rich traffic management information.
If cities are serious about improving traffic flows…then technologies like [Distributed Acoustic Sensing] DAS have a key role to play in gaining intelligent insights, managing motorways and roadways, and managing transport networks more efficiently.
When it comes to smart cities, DAS is set to be a vital part in the technology puzzle.
Due to its flexibility, DAS is likely to be one of the first ‘live’ installations of true smart city technology.
