【摘要】：暴風(fēng)雪天氣下信息獲取是保障高速公路使用者出行安全的重要手段,研究駕駛員信息獲取策略可以保障道路使用者信息獲取的及時(shí)性及成功率。選取樣本量為200的不同車型駕駛員進(jìn)行調(diào)查問卷,統(tǒng)計(jì)駕駛員出行目的和信息需求,利用綜合分析法建立信息需求邏輯模型;通過調(diào)研依托工程現(xiàn)有信息發(fā)布設(shè)施及信息發(fā)布手段,分析現(xiàn)有方案存在的不足,提出改善建議;總結(jié)信息發(fā)布潛力技術(shù),通過對(duì)其進(jìn)行可行性分析,利用信息融合手段對(duì)已有設(shè)施及網(wǎng)絡(luò)技術(shù)進(jìn)行融合,建立綜合信息發(fā)布系統(tǒng);從發(fā)布時(shí)段、發(fā)布對(duì)象、發(fā)布范圍、發(fā)布內(nèi)容及發(fā)布方式進(jìn)行信息發(fā)布方案設(shè)計(jì),提出信息發(fā)布流程,為冬季暴風(fēng)雪天氣下高速公路管理提供技術(shù)支撐。
[Abstract]:Information acquisition is an important means to ensure the safety of freeway users in snowstorm weather. The study of driver information acquisition strategy can ensure the timeliness and success rate of road users' information acquisition. In this paper, the drivers with 200 samples are selected to carry out the questionnaire, the purpose of travel and the information demand of drivers are counted, and the logical model of information demand is established by comprehensive analysis method. Through investigation and research on the existing information release facilities and information release means of the project, this paper analyzes the shortcomings of the existing scheme, puts forward some suggestions for improvement, summarizes the potential technology of information release, and analyzes its feasibility. The information fusion method is used to fuse the existing facilities and network technology, to establish a comprehensive information publishing system, to design the information release scheme from the release period, the release object, the distribution range, the release content and the publishing method. Information release flow is proposed to provide technical support for highway management in winter snowstorm weather.
