  1. 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。
  2. The time headway distribution of the simulation system based on this model can be tuned by two simple parameters, so it can accord with different time headway distribution rule in condition of practical unsaturated traffic

    基於該模型建立的模擬系統，憑借兩個簡單的參數來調節不同車速的期望車頭間距，使車頭時距分佈規律符合交通未飽和時車頭時距的具體分佈情況。
  3. The model assumes that every vehicle tends to keep expected time - headway and each vehicle synchronously updates its velocity by estimating the velocity of the head vehicle, the distance headway and the probability of random slowdown

    該模型假定行駛車輛都趨向于保持一個期望的車頭時距，通過對前車速度和車頭間距的估計，並考慮隨機減速的影響對車速進行同步更新。
  4. Based on the comprehensive analysis of the road traffic flow ' s characteristics due to the bus stop without bus bay, the multivariate linear models of the speed and the headway are formed with the variables of the stop frequency, the stop time, the overall length of the stop and its reserve time of the bus and the vehicle flow applying the software of excel, and then the strict mathematical checks are made

    文章首先比較全面地分析非港灣式公交停車影響下道路交通流特徵，然後藉助于excel軟體，構建關于公交停車頻率、公交停車時間、最大公交停車長度及其存在時間、道路流量的車速和車頭時距多元線性模型，並進行了嚴格的數學檢驗。
