摘要
将一套车载实测系统安装在一辆昌河微型面包车上,研究合肥市不同道路的行驶状况。用速度、加速度等行驶特征参数为准则数,通过将记录的车速曲线在停顿处分割成运动学片段的方法来研究交通状况特征。根据统计分析的概率随机选择并重组实际运动学片段,得出一个基于实际汽车速度、加速度等准则数的行驶工况。
Experiments were carried out by an on-board real-time measuring system mounted on a ＇Chang he＇ mini-van and the results were statistically analyzed to get the characteristics of vehicle mode in Hefei. A typical driving mode was obtained based on criteria such as real speed, acceleration. The characteristics of vehicle mode were got by cutting the recorded speed line into segments at the halt points. According to the statistical analysis and the probability randomly selected, the segments were selected and reunited. And a typical driving mode was got based on criteria such as real speed, acceleration.
