Summary: The problem of synchronicity quantification based on event occurrence time is currently heavily researched in various fields. Synchrony measurement methods provide an effective approach to explore the spatial propagation characteristics of extreme events. By using event coincidence analysis, a directed weighted network is constructed to investigate the direction of correlations between event sequences. The synchrony of traffic extreme events of base stations is measured based on trigger event coincidence. The study analyzes the topology characteristics of the network and the spatial propagation features of traffic extreme events, including the propagation area, influence, and spatial aggregation. This research establishes a network modeling framework for quantifying the propagation characteristics of extreme events, which is beneficial for further studies on extreme event prediction. Additionally, it examines the differences between precursor event coincidence and trigger event coincidence, as well as the impact of event aggregation on synchrony measurement methods. The study can serve as a reference for analyzing extreme climatic events such as rainstorms and droughts in the field of climate.
