Abstract:With the change of urban land policy, the planning of plot and supporting municipal infrastructure in industrial zone is gradually refined. Especially under the background of narrow rods and dense network, the turning radius of vehicles in the industrial zone is large, and the safety requirements are high. There is a coordination relationship between the opening of the plot and the section of the road. It is necessary to carry out the refined research on the organization of the industrial zone plot. In the planning stage, the plot opening, turning radius and adjoining road width are reasonably planned and pre-controlled in order to ensure the later use convenience of industrial plot.
