| Abstract: | The traffic division problems were focused in this paper.Firstly,nine indicators were selected from the conditions of transportation facilities,traffic operating and traffic environment.And then the principle of the initial traffic division with the method of unsupervised classification,ISODATA algorithm,was described.Based on this,urban traffic cluster system was explored.The result of classification is effective.The division of traffic network of Beijing City was introduced as a case of study. |
