The development of network media causes great impact on the communication patterns in our country, the media transfers from the disseminators as operation center to the acceptant as operation center. of course, our country gets the new spread way at present, and network media become a new window to helping readers both at home and abroad to understand china
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
Such was the course adapted by him.
We sent advance copies of the new course book to the teacher and the students who were to use it
" of course - if you ain t afeard.
