| Summary: | 碩士 === 中原大學 === 土木工程研究所 === 93 === Information of trip interchange between areas is vital in most transportation planning practices; however the OD data collecting is difficult, costly, and frequently fragmented. Compared to such complication, it is relatively easy to gather ramp inflows and outflows of an access-controlled. The estimation of trip interchange between corridor access points is different from urban road network which has open limits with zonal trip distribution estimated by conventional gravity models in use of zonal attributes. This study aims to develop a simplified estimation process of origin-destination matrixes on access-controlled corridors without branches based on limited and easily attainable data, e.g., ramp flow counts. The estimation method is also application on other transportation system with similar forms such as bus lines or regional rails.
The estimation process in this study was based on Fluid Analogy Method proposed by Tsygalnitzky(1977) and applied on closed-ended tube system. In the first part of the study, the basic estimation method was developed and the factor of relative attractiveness derived as well as systematically examined. Next, the estimation process was modified by allowing incomplete ramp flow counts and invited rectifying mechanism in the second concluded that the modified estimation method is able to generate satisfying OD estimates without use historical, complicated, or sampled data. More conclusions and suggestion for future works were stated.
