SLShuang LuoChongqing Jiaotong University KCKuan ChenChongqing Jiaotong University RCRuilin ChenChongqing Jiaotong University

Key Points

The aim is to understand how diverging drivers navigate challenges in closely spaced tunnel-interchange structures by adapting their visual attention.
Conducted a field study observing driver behavior in tunnel-interchange structures.
Assessed drivers' visual attention engagement and allocation.
Analyzed visual search strategies used by drivers.
Drivers show varying levels of visual attention based on the complexity of the tunnel-interchange structures.
Adjustments in search strategies are correlated with the proximity of guide signs.
Findings can inform better design and placement of guide signs to aid driver navigation.

Abstract

This study reveals how diverging drivers navigate the challenges of CSTI structures by adjusting their visual attention engagement, visual attention allocation, and visual search strategies. The findings can offer a reference for designing and placing guide signs in CSTI structures.
