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。 -
