Abstract
A method of estimating one or more properties of traffic of vehicles passing along roadway segments of a road network includes receiving, from a radio navigation receiver located at each vehicle of a subset of the vehicles, first properties of each of those vehicles, and receiving, from a distributed acoustic sensor, signals representing acoustic vibration caused by the traffic at sensing optical fibers that extend along the roadway segments to determine second properties of the traffic in the road network. The method further includes combining the first properties received from each vehicle in the subset of vehicles with the second properties of the traffic to estimate third properties of the traffic that are used to provide navigation services in the road network.
