Improvement of the Traffic District Partition in Resident Trip Investigation

In order to reduce the workload and cost in resident trip investigation,data including age,profession,incomes and vehicle ownership rate of the late survey were used.According to the equivalent matrix fuzzy of cluster analysis,and with MATLAB programming,the optimal classification numbers were determined using F-statistics,and the traffic districts were re-classified.By this way,only a traffic district was chosen from each type traffic zone,the accuracy will meet the demands when conduct a traffic investigation.To verify the method,a fuzzy C-means cluster was used.The results showed that the fuzzy cluster analysis method can be conveniently applied to the partition of traffic zone in resident trip investigation.
