And the deficiencies are pointed out in present researches, such as highway capacity, level - of - service, influence factor of road alignments, etc. from these, it has confirmed that the thesis should be studied from rational analysis, quantitative analysis of level - of - service, impact on capacity of road alignments, setting - up simulation model, etc. the high - accuracy gps dynamic data acquisition appearance is proposed to be used for the first time to carry on the experiment of overtaking on two - lane highways, and experiment scheme is designed according to the driver ' s perceive to judge each overtaking course. based on the experiment data, it can get two important parameters of acceptant gap ? the critical gap of overtakable time headway and returnable time headway through data processing, which can offer the strong support to the research of two - lane highway capacity with qualitative and quantitative analysis. besides, the experiment methods is provided to observe overtaking ratio and to measure the
研究中首次提出了運用高精度gps動態數據採集儀對雙車道公路上的超車行為進行觀測，設計了根據駕駛員感受度來衡量超車過程的實驗方案，並通過後期數據處理得到了超車過程中兩個重要的可接受間隙參數-可超車車頭時距和可回車車頭時距的臨界間隙值，為定性和定量分析雙車道公路通行能力提供有力的數據支持;同時，還提出了觀測超車率的實驗方法以及測量加速度干擾的實驗方案，統一了計算加速度干擾的時間統計間隔，為雙車道公路的服務水平量化研究奠定基礎;最後還簡單介紹了駕駛員問卷調查法和模擬程序中模型參數標定和驗證的數據採集方法。 -
A recommend value of appropriate roadbed height is put forward according to the sand dune type and the highway grade, make investigation to the sand harm and other problems of built highways in desert areas gathering the related materials of present day highways, and then make comprehensive and systematic statistics to related data and racious factors which affect the roadbed height ; analy the suitable roadbed height for the windblown sand drift passes through smoothly according to the open country windblown sand field test ; test and verify the outcome according to indoor wind tunnel test ; finally a appropriate recommend roadbed height value will be put forward for different grade highways in different areas, which is according to the analysis of roadbed stability the roadbed height economic analysis and different use requirement to different grade highways
收集現有沙漠公路的有關資料，對全國已建沙漠公路進行沙害及其他病害調查，對相關數據和影響沙漠公路路基高度的各種因素進行綜合系統地統計分析；通過野外風沙流場測定，分析適宜風沙流順利通過的路基高度；通過室內風洞試驗進行驗證；結合路基穩定性分析、路基高度的經濟性分析，考慮不同等級公路的使用要求，最終提出不同地區不同等級沙漠公路路基填土高度的合理高度建議值。 -
