Abstract: Buliding large developmental projects in urban fringe regions has become a civil developing trend under the condition that urban area expanded contiously. Based on analyzing the limitation of traditional traffic impact analysis, this paper presents the fundamentals of passage traffic analysis. The object is selected to be those traffic passages constructed within short distance in the proposed project. The paper advocates traffic bottleneck studies according to surrounding passage traffic, and examines passage traffic sensitivity based on the impact analysis of the under-constructed project on passage traffic. It is necessary to identify the passages that the project should take. Finally, the proposed theory is illustrated by an example. The passage traffic analysis effectively dissolved the conflict between undergoing construction and passage traffic, which makes improvement of traditional traffic impact analysis. In this way, it avoids significant side effect on the passage traffic after construction.

Key words: passage traffic, traffic bottleneck, urban fringe region, traffic impact analysis (TIA)
