基于视觉感知的匝道—隧道衔接段交通诱导设施设计与评价

Design and evaluation of traffic induction facilities for ramp-tunnel connecting sections based on visual perception

  • 摘要: 匝道—隧道衔接段是城市道路网络中的关键交通节点,安全风险尤其突出,采取合理的诱导措施对提升该区段的驾驶安全性具有重要意义。通过构建6种诱导措施方案,并结合视觉测试指标与TOPSIS法(Technique for Order Preference by Similarity to Ideal Solution)对各方案进行综合评价。结果表明,在主线及分流区行驶时,方案五(采用全部诱导措施)下驾驶员对中央视区的注视兴趣度最高;在隧道区段行驶时,方案三(无隧道侧壁优化)及方案六下驾驶员的兴趣区分布占比几乎一致,说明驾驶员在隧道区段的注视兴趣主要变侧壁条件影响;综合考虑各项诱导措施的提升效益,匝道—隧道衔接段诱导措施效果最优的方案为方案五(采取全部诱导措施)。

     

    Abstract: Ramp-tunnel connecting sections as critical traffic nodes in the urban road network, undertake the convergence and passage of a large number of vehicles with particularly prominent safety risks, adopting reasonable induction measures is of great significance to improving the driving safety of such sections.In this study, six implementation schemes with different induction measures were constructed, and each scheme was comprehensively evaluated by combining visual test indexes and the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution). The results show that when drivers are driving on the main line and the diversion area, Scheme 5 (with all induction measures adopted) enables drivers to achieve the highest gaze interest in the central viewing area compared with other schemes; when driving in the tunnel section, the proportion of interest area distribution of drivers under Scheme 3 (without tunnel side wall optimization) and the original scheme is almost the same, indicating that drivers' gaze interest in the tunnel section is mainly related to side wall conditions. Comprehensively considering the improvement benefits of various induction measures, Scheme 5 (with all induction measures adopted) is the scheme with the optimal design effect for ramp-tunnel connecting sections.
