What is the Red Line of the Road, the Green Line, the Purple Line, the Blue Line, and the Yellow Lin

The boundary line of the planned urban road width reflects the width of the road red line, the urban green line refers to the control line of various types of green space in the city, and the city purple line refers to the national historical and cultural city.

In urban planning, what does it mean to have a blue dotted coil outside the red line?

The boundary line of the planned urban road width reflects the width of the road line, which includes: the width of the road required for the passage of motor or non-motor vehicle and pedestrian traffic; the additional width required for laying underground and above-ground pipelines and urban utilities; The width required to plant a street tree.

The green line of the road is used to represent the boundary of the green land on the road, and refers to the control line of the range of various green spaces on the urban road. The road green space formed by the road green line is a kind of urban green line, and the urban green line also includes: public green space, protective green space, production green space, residential green space, unit attached green space, scenic woodland, etc., must be in accordance with the relevant standards for green space construction.

Red line: refers to the approved red line of construction land, the red line of planned roads and the red line of construction;

The so-called "construction red line" refers to the boundary delineated by the local people at or above the county level authorized by the Highway Law of the People's Republic of China in accordance with the principle of ensuring the safety of highway operation and saving land to define whether permanent non-highway facilities can be built on both sides of the highway. The control of the building red line is the management process in which the road administration department strictly prohibits any unit or individual from building permanent off-highway facilities within the scope of the building red line in accordance with the provisions of the laws and regulations of highway management.

The property line consists of the right of way and the building control line. The red line of the road is the planning control line of the land used for urban roads (including residential roads); The building control line is the control line at the base of the building. On the side adjacent to the road, the red line of the road is generally used as the building control line, and if it is necessary for urban planning, the competent authority may set a building control line in addition to the road line, which is generally called the construction of the setback road red line.

No building may exceed a given building line.

The General Principles for the Design of Civil Buildings (JGJ37-87) stipulates that the steps, platforms, window shafts, underground buildings and building foundations of buildings, except for the urban pipelines connected to the base in the base, other underground pipelines are not allowed to highlight the red line of the road. Architectural protrusions that are allowed to protrude from the right line of way: 1 Over the pavement floor:

1) More than 2 meters are allowed to protrude window sashes and window covers, and the protrusion width is not more than 0 4 meters; (2) 2 More than 50 meters are allowed to protrude movable sunshade, and the protruding width should not be greater than the width of the sidewalk minus 1 meter, and should not be greater than 3 meters; (3) 3 More than 50 meters are allowed to protrude balconies, convex windows, canopies, eaves, and the protruding width should not be greater than 1 meter; (4) More than 5 meters are allowed to protrude the canopy and eaves, and the protruding width should not be greater than the width of the sidewalk by 1 meter, and not more than 3 meters. 2. Over the road without sidewalks: (1) 2 50 meters above the sash and window cover are allowed to protrude, and the protruding width should not be greater than 0 4 meters; (2) More than 5 meters are allowed to protrude canopies and eaves, and the protruding width should not be greater than 1 meter.

Green line: refers to the control line of various types of urban green space;

Blue line: refers to the territorial boundaries for the protection and control of urban surface water bodies such as rivers, rivers, lakes, reservoirs, canals and wetlands determined by urban planning;

Purple line: refers to the boundaries of the protection scope of historical and cultural blocks in national historical and cultural cities and historical and cultural blocks announced by the people of provinces, autonomous regions and municipalities directly under the Central Government, as well as the boundaries of the protection scope of historical buildings outside historical and cultural blocks that have been announced and protected by people at or above the county level;

Black line: refers to the control range of the land used for high-voltage lines;

Yellow line: refers to the control boundary of urban infrastructure land that has an impact on the overall development of the city, is determined in the urban planning, and must be controlled;

Orange Line: refers to the control boundary of the land area for railway and rail transit.

As for the white line, I haven't encountered it yet in the learning stage, so I hope the master will guide me).

The building red line, also known as the "building control line", refers to the boundary between the buildings or structures (such as exterior walls, steps, etc.) along the street on both sides of the urban road in urban planning and management. No building or structure facing the street shall exceed the building line.

The blue line of architecture refers to the territorial boundaries for the protection and control of urban river systems and water source projects such as rivers, lakes, reservoirs, channels, constructed wetlands, and flood detention areas determined by urban planning, as well as the planning reserved areas demarcated due to the needs of river improvement, river greening, and river ecological landscape construction.

Yellow line: refers to the control boundary of urban infrastructure land that has an impact on the overall development of the city, is determined in the urban planning, and must be controlled;

The "five-line" control system is a mandatory part of urban planning, and is applicable to different levels of urban planning, from urban master planning to regulatory detailed planning.

The "red line" delineates the construction land approved by the Planning Bureau, which is mainly set up for road control, and the management of the "red line" is reflected in the planning and management of the plot ratio, construction density and construction height; The "green line" delineates public green spaces, parks, unit green spaces and green spaces around the city in the city; The "Blue Line" delineates the city's water surface; The "Purple Line" delineates historical and cultural districts; The "yellow line" delineates the scope of influence of major infrastructure land. In all areas that have been demarcated, urban construction shall not be arbitrarily encroached upon, and all construction in the area will be strictly controlled.

<> yellow line is used to distinguish lanes in different directions, and is generally drawn in the middle of the road, like a separate compound belt, separating the road into two directions

1. Regardless of the single yellow line or the double yellow line, as long as it is a solid line, it is strictly forbidden to cross, such as overtaking, turning, U-turning, etc. The line should not be crossed unless there are special circumstances.

2. Regardless of the single yellow line or the double yellow line, as long as it is a dotted line, you can overtake or make a U-turn under the condition of ensuring the safety of the 100 certificates.

3. The single yellow line is generally used on roads within 4 lanes in both directions (including bicycle lanes), and the double yellow line is generally used on wider roads.

4. If there are double yellow lines, one degree is a solid line, and the other is a dotted line, which side of the dotted line is, the vehicle on that side can temporarily cross from there, such as a super-intelligent car or turn.

2. The white line is used to distinguish different lanes in the same direction, and everyone is in the same direction.

1. The dotted line can be merged and the lane can be changed.

2. The solid line is not allowed to merge, and the lane cannot be changed at will.
