A visual analysis method, device and medium for traffic simulation decision-making

Abstract

The application discloses a visual analysis method, equipment and medium for traffic simulation decision, wherein the method comprises: acquiring input data, wherein the input data comprises a road network with static attributes and a set of OD pairs containing OD travel related attributes; modeling the road network as a directed graph; assigning OD travel to paths and roads in the road network, calculating actual traffic volume and actual travel time of each road based on a traffic assignment algorithm; and constructing and displaying a map view and a comparison view according to the directed graph, the actual traffic volume and the actual travel time of each road. The application realizes the map view supporting the interactive road network editing function and the comparison view combining the history tree and the matrix, provides a new way to show the attribute comparison of multiple road network states, and supports in-depth analysis and decision-making process in the geographical background and attribute context.
