碩士 === 國立交通大學 === 土木工程研究所 === 83 === Origin-Destination(O-D) matrix is an important data in ur- ban transportation planning. Conventional method such as home interview surveys for obtaining O-D matrix in urban areas are prone to considerable sampling error and become prohibitively costly. For these reasons several researchers try to develop methods for estimating O-D matrix from link traffic count data . Most previous research works on O-D matrix estimation conce- ntrated on rule of user-equilibrium whiich analyzes driver''s behavior, but its condition is too stringent.Therefore, the p- urpose of this thesis to develop an estimation method which is more correspond real driver''s behavior. For vehicles continue to survey at study area for five da- ys.We discover which drivers are uncertain clutch network suf- ficient information, uncertainly selects shortest path and it has the phenomenon of use habitual path. This thesis with hab- itual domains makes drivers select path basis. Assume every d- river be able select habitual path. Path habitual drive proba- bility adopts the form of logit model. Use the method of leas- t square to construct the model of O-D matrix estimation.
