Abstract
En 中文
To address space constraints in dense freeway interchange sections, this study proposes the Traffic Control Device Selection Model for Traffic Information (TCDSM-TI). It overlays optimised signs on existing information via selected facilities to convey road details effectively. A driving simulation experiment involving 39 drivers evaluated various designs. The results indicate the following: (1) Iterative TCDSM-TI optimisation, statistical validation, and comprehensive assessment are required because of the varied optimisation effects of different sign combinations and sequences. (2) Optimal sign combinations are crucial for enhancing route clarity and driving stability. (3) Sign effectiveness is closely linked to road geometry, with multiple exit warning signs enabling smoother speed adjustments. A 2.5 km exit guide sign should be optimised for continuous guidance, while ground text guides and navigation prompts should improve comfort and stability. This study supports the optimised design and practical application of traffic facilities in dense freeway interchanges, thereby mitigating the negative impacts of complex road conditions on drivers.
