However, the traditional ways which obtain the O-D data usually cost a large amount of time, money, and human resources. In addition, since it could be affected by weather, artificially negligence or mechanical disorder, the O-D data we obtained might have low accuracy. Therefore, the research on the model in O-D estimation has been a continuous study topic in transportation. Due to the assignment between each O-D pair in corridor is hard to obtain, so the data set used by estimation in research are often the in-flow and out-flow counts of access ramps, and how to use these flow data to build the relationship between each O-D pair is very important in the model. This research is based on fluid analogy method proposed by Tsygalnitzky, following the research of Kuo(2005) and Lin(2006), continued to discuss the development and application of fluid analogy method on O-D estimation of access-controlled corridor. The hypothesis used in the past, including the unitary factor of relative attractiveness for all day long and the fixed distance among ramps were re-examined in this research. For the modified model in this study, the fixed factor of relative attractiveness in the time-dependent fluid analogy method varies with time, and so do the distances among ramps. According to the simulation tests, the model was able to deliver sound results in the situation of flow varying along time dimension. Yu-Chun Liao 廖祐君 2007 學位論文 ; thesis 106 zh-TW |
