In Orange County, CA, truckers and other motorists have a new way of
calculating their travel time.
The state’s Department of Transportation has embedded 5,500 sensors in
the pavement on freeways. The devices will determine whether traffic is moving
normally – or at a snail’s pace.
According to the Orange Country
Register, the information is then transmitted to overhead electronic
message boards along the routes, which will inform drivers how long it will
take them to reach given points.
