| Περίληψη: | Autonomous vehicles (AVs) are rapidly entering commercial deployment, but large-scale empirical comparisons with human driving remain limited. Using naturalistic data from two demonstration zones in Beijing and Shanghai, this study analyzes 444 vehicles and over 100 million 1Hz trajectory records from multiple permitted AV operators. A hierarchical segmentation pipeline merges any sub-five-second AV/manual mode-indicator switch with adjacent segments to suppress transient flicker that would otherwise be misread as takeover events, yielding stable segments for multi-granularity comparison of longitudinal dynamics, ride comfort, and human-machine interaction. The two zones represent contrasting operational regimes: a congested Beijing demonstration zone and a higher-speed Shanghai commercial robotaxi corridor, allowing recurrent cross-regime patterns to be separated from regime-sensitive variation. Routine jerk levels are similar between AV and human driving, whereas AV jerk is 47.5% lower during active longitudinal maneuvers in Shanghai. After filtering near-stationary events, in-motion takeovers are classified into Smooth, Braking, and Accelerating types. Accelerating takeovers account for roughly one quarter of in-motion events in both cities, whereas Braking dominates Shanghai and Smooth transitions dominate Beijing. An exposure-adjusted Shapley additive explanations (SHAP) analysis with AV traffic volume as a fixed offset identifies distinct environmental associations: curvature and sinuosity rank highest for Braking, whereas intersection proximity ranks first for Accelerating. Total disengagement counts therefore conflate behaviorally distinct intervention types and city-specific operational variation, both visible only after decomposing events by post-takeover dynamics and stratifying by operating regime.
