The invention provides a method of selecting a representative node in a traffic road, a system and a client. The method comprises the following steps of acquiring map data corresponding to a preselected closed area and running data of a floating vehicle; dividing the closed area into a plurality of basic meshes on average; according to the running data, acquiring a floating vehicle passing frequency of each basic mesh in the closed area; dividing the closed area into subareas whose number is less than the number of the basic meshes on average; marking the basic mesh with the highest floating vehicle passing frequency in the subareas as a node mesh; matching the node mesh with the map data; selecting a POI point which matches with the node mesh in the map data as a node. By using the method, the system and the client of the invention, the running data is taken as a basis so as to select the node, and bases of a scientific decision, prediction analysis and a technology support are provided for transportation planning and path navigation.
