Regional Road Network Od Survey A Number Of Technical Studies

On the basis of the basic theory study of Road-network OD Survey, this paper made a deep research into the key technic problems of the former stage and data disposal stage of region Road-network OD Survey, including: the traffic zone division method based on the Fuzzy Clustering Analysis, the zone borderline setting method of OD survey spots. In the light of the subjectivity in former methods of OD survey time confirming, according to the feature of Road-network OD Survey, this paper put forward a new method that can objectively confirm the OD survey time through comprehensively analyzing the road traffic feature and the road physical feature. These above methods have been applied into the Road-network OD Survey practice of HeBei province and got satisfactory results. According to the thought of zone borderline setting method, this paper put forward an OD table merging method based on the zone borderline setting method. Aiming to meet the practical need of Road-network OD Survey in our country, the problem of merging different time OD tables was put forward, and a economical solving method of this problem was subsequently worked out. In the end, the TQM (Totle Quality Management) system of region Road-network OD Survey was formed out through applying the relative theory of Management Economy theory.
