Evaluating the traffic development level(TDL) accurately plays a great significant role in monitoring the processing constructed from the Jinpu new district in Dalian. This paper refined a term of index hierarchy fitted on the study area according to the characteristic of its TDL. Based on the Geographical National Census Production(GNCP) and other relevant auxiliary thematic data, this study computed those values in the index hierarchy using street property information as the basic unit. Meanwhile, the Entropy Weight Algorithm was used for gaining the corresponding weights of the index. And then, the TDLCI(Traffic Development Level Comprehensive Index, TDLCI) of our study area was calculated by Weighted Average Method. According to the thematic map of TDLCI, Not only the current traffic development situation of every street in the new district it reflected, but also can provide guidance for the further construction.
