Road network state statistics method and device and computer-readable storage medium

The embodiment of the invention discloses a road network state statistics method and device and a computer-readable storage medium. The method comprises the steps of acquiring the data information ofa target node; according to the alarm rules corresponding to the data information, determining the state level of the target node; judging whether the target node has child nodes; if so, determining the comprehensive state level of the target node according to the obtained state level of each child node; gathering the target node 's own state level and comprehensive state level to construct the road network state information. According to the above-mentioned processing method, the self-state level and comprehensive state level of each superior node in the whole road network structure can be determined. When displaying the status information of all nodes in a certain level through the display portal map page, the user can intuitively understand the status of each child node in the next level according to the compre
