The invention discloses a high-grade road (highway and city expressway) multi-bottleneck-point congestion evolution space-time range identification method and aims to overcome the defect that in existing road bottleneck congestion evolution range identification, mutual influence among multiple bottlenecks cannot be identified. The method comprises the steps of: firstly, carrying out traversing and operation on data in time and space on the basis of data acquired by traffic flow detection equipment in a multi-bottleneck region; according to a traffic flow theory building algorithm, carrying out real-time operation and reproduction on boundaries of traffic flow congestion and dissipation and simultaneously, identifying and judging relevance among bottleneck points in the region; and finally, obtaining a complete congestion evolution space-time range in the multi-bottleneck-point region.
