To explore the impact of travelers' subjective spatial perceptions on travel behavior in the context of distinct urban terrain, this study takes Lanzhou, a typical rivervalleytype city, as an example. It establishes an integrated model of SEMLogit and explores the impact of the spatial perception of rivervalleytype city travelers on rail transit travel mode choice based on questionnaire data. The results show the following: ① Compared with the logit model without considering travel space perception, the goodness of fit of the logit model considering travel space perception by SEM increased by 0.234, and the prediction accuracy increased by 7.75%. ② The spatial perception of travelers in rivervalleytype cities has a significant positive impact on the choice of rail transit travel intention and behavior. ③ The spatial perception of travelers in the rivervalleytype city from five aspects, including the unnecessary detour, rivers in the river-valley-type city, wasp waist blockage, convenience of inter-group travel, and degree of being affected by road slope, l significantly influences travelers in the river-valley-type city to choose rail transit. The degree of influence decreases sequentially among these factors.
