Aimed at highway network layout theory development and hotspot problem of highway building and social economical development,the dissertation Focus on the analysis method of local highway network topology based on area development theory, harmony development of local economy and layout of highway network. The final purpose is to realize the combination of transportation,economy, and town overall arrangement in space.(1) Having analyzed town arrangement in space and its transportation affecting factors,it is studied that the interacted regulation between highway network and town space layout. The factors that decide the form and development of highway network are explored. The research field covers the commonly developed law of local space distribution.(2) Begin with mode analysis of transportation economy evaluated with time span, it is investigated gather-scatter effect of expressway. The influence of expressway economic lane to highway network layout is concluded.(3) Several principles of highway network topology are proposed according as the rule of local highway network and town space layout, which are: the local city space layout, town node selection sequence and route selection, form and object and principle being considered together. Some new concepts are proposed such as city space development degree, city central degree, space economy contact intension. The combination of highway network, social economy, and city hierarchy depress the disadvantage of former highway network planning. By introducing the ant arithmetic of dynamic route selection, the problems are set forth how to promote utility efficiency and to design highway network topology.(4) Theoretical analysis is proceeding on the relationship of highway construction and social economy development on the aspect of macro-economic. The definition of continuable harmony development of highway construction and social economic is given. It is set forth that evaluation model of highway construction and social economic harmony development with DEA model and AHP confine cone, together with object scale of local highway network at different social
