Researchers are studying ways to use existing fiber-optic cables as distributed sensors to collect data on city road conditions. Verizon and NEC recently conducted a proof-of-concept field trial
"Distributed fiber optic sensing techniques offer powerful tools for the monitoring of long, linear assets, such as highways, " reports Gareth Lees, FOSA Technology Committee Chairman.
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.
Fotech’s trials in Calgary are one of the first instances where we have shown the value of DAS monitoring platforms by offering the transport insights smart cities will need.
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.
