Abstract (en)

[origin: WO2011120194A1] This invention discloses a method, system and node for journey time measurement in a road network. The method includes: designating multiple measured points in the road network, placing a node at each of the multiple measured points, and detecting characteristic of a car sequence sequentially passing through the measured point of the node; determining, at a first node, one or more neighbor nodes of the first node, and reporting to a neighbor node the characteristic of the car sequence of the first node, wherein the first node is any node in the road network; comparing, at the neighbor node, the characteristic of the car sequence of the first node and the characteristic of the car sequence of the neighbor node to find a matching position; obtaining, at the neighbor node, a journey time from the first node to the neighbor node according to the matching position.
