Boundary Line Control and Cross-sectional Design of Urban Roads in Inventory Development Stage
The city is facing with the transition from spatial expansion to stock renewal in China,need to study the urban road network planning facing the new requirements of determine boundary line and cross-sectional form of roads.Based on the requirements of the current relevant standards for road boundary lines,combined with the necessity of planning and the feasibility of construction,a method is proposed to optimize the already planned boundary line of urban roads.Based on the requirement of managing the territory space through"three zones and three lines",and the requirement of dividing the urban roads into"three major categories,four medium categories,eight minor categories"according to the functions,a cross-section matrix is constructed which includes the road category and the area where the road is located,and the principles of cross-sectional design for different types of roads are summarized.Taking Nantong City as an example,this article describes how to apply the above methods to determine or optimize the boundary line and cross-sectional design of urban roads in typical cases such as the width of the already planned boundary line is too large,too small or the road crosses the agricultural zones.
