Abstract: Interchange ramp areas present complex environments where drivers' mental workload varies significantly.Thedrivers'mental workloads were analyzed while theycrossed diferent interchange ramp types,with thedataofdriver heartratesbeing collected byreal-vehicleexperiments.Amental workload evaluation system was established byusing dual-modal electrocardiogram indicators (the HR (heart rate) andthe HRV(heart rate variability)).The results show that drivers experience higher mental workload in hub interchange ramps than that in general interchange ramps.Within interchanges,the mental workload isthe highest insmall-radius loopramps,followed bytheleft-turnsemi-directionalramps,and the lowest in right-turn directional ramps.Drivers also exhibit greater tension in hub interchange scenarios.The mental workload demonstrates a significant negative correlation with ramp radius.The authors recommend installing decelerationsigns inadvance on hub interchange sections
