From the interaction between the industrial structure and layout of the road network,this paper analysis the factors in the urban road network layout.

The rapid development of economy and society in inserting regions put forward highway network distribution new and higher request.

The lace distribution model of the petroleum processing and cefining plays the most important roles in economic development speed,industrial structuce adjustment and three times of industrial escalation and renewal in certain region.

This paper introduces the integer planning and layout pattern of Suzhou industrial park,illustrates the planning and layout concept of each function area as residential area,industrial park,landscape and leisure area,public utilities land-use and greenbelt,and discusses the concept of road planning,in order to offer experience for the planning of post-transcendent cities.

Numerical experiments show that initial layout points(layout pattern) considerably affect solution quality and computational efficiency,when layout problems are solved using deterministic-search algorithms(e.
