【摘要】：目前交通需求与交通供给之间的矛盾，导致交通拥堵、交通安全等各种问题越演越烈，城市路面交通正面临发展的极限。建设地下隧道式道路，能有效解决当前存在的部分问题。但是地下道路与地面道路之间存在很大的差异。从空间上来看，地下道路内部空间是封闭的，景观单一，通风条件较差；与地面道路的交通状况相比较，地下道路的横向和竖向都受到宽度限制，只能在固定出入口进出等，这些差异都说明地下道路的驾驶环境明显差于地面道路；再加上没有自然光照等条件限制，地下道路的视认情况变差，尤其是对交通标志的视认。首先，文章以地上道路和地下道路驾驶环境为对比、设置交通标志和不设置交通标志为对比，进行正交试验。并采用模拟驾驶实验和问卷调查相结合的方法，收集数据。以该数据为基础，并以驾驶特性为因变量，采用多因素方差分析的方法，找出影响驾驶安全的显著因素。研究结果显示，地下道路有标志路段，驾驶员的驾驶特性最差。其次，文章以上述研究结果为基础，重点研究地下道路有标志路段的驾驶场景下，驾驶员对交通标志视认的影响因素，采用Logistic回归方法，建立影响因素模型，找出关键影响因素。最后，总结研究结果，，提出相应的建议措施，为地下道路交通安全管理提供建议措施，以供相关部门参考。文章最后还列举了本文的研究缺陷，并提出下一步的研究计划。
[Abstract]:At present, the contradiction between traffic demand and traffic supply leads to traffic congestion, traffic safety and other problems, and urban road traffic is facing the limit of development. The construction of underground tunnel road can effectively solve some of the existing problems. However, there are great differences between underground roads and ground roads. From the spatial point of view, the internal space of underground road is closed, the landscape is single, the ventilation condition is poor; compared with the traffic condition of ground road, the transverse and vertical direction of underground road is limited by width, and can only enter and leave at the fixed entrance and exit, these differences show that the driving environment of underground road is obviously worse than that of ground road. Coupled with the lack of natural light and other conditions, the recognition of underground roads becomes worse, especially the recognition of traffic signs. First of all, the orthogonal test is carried out by comparing the driving environment of the above-ground road with that of the underground road, and setting the traffic sign and not setting the traffic sign. The data were collected by combining simulated driving experiment with questionnaire survey. Based on the data and driving characteristics as dependent variables, multi-factor variance analysis is used to find out the significant factors that affect driving safety. The results show that the driving characteristics of drivers are the worst when there are marked sections of underground roads. Secondly, based on the above research results, this paper focuses on the influencing factors of drivers' recognition of traffic signs in the driving scene of marked sections of underground roads. Logistic regression method is used to establish the influencing factor model and find out the key influencing factors. Finally, the research results are summarized, and the corresponding suggestions are put forward to provide suggestions for underground road traffic safety management for reference by relevant departments. At the end of the paper, the research defects of this paper are listed, and the next research plan is put forward.
