The process of expressing road in different patterns or shapes is called a road pattern. They are very essential to manage high traffic. The main aim of the road pattern is to connect every place/ building in a network form. Proper road patterning plays a vital role in saving a life in emergency condition like fire fighting, medical emergency conditions(like a heart attack), etc.
Road patterns can be classified into six types. They are:
Types of Road Pattern
1.Rectangular or Block Pattern
-In this pattern, the whole part is divided into rectangular blocks of the plot which intersects streets at right angles.
-The main road passing through the central area should be sufficiently wide and the branch road may be comparatively narrow.
– They are considered unsafe than other patterns because vehicles in opposite directions meet at an intersection.
– The aesthetic view is very beautiful and the geometry of this pattern is easy to understand.
2. Radial or Star Block Pattern
-In this pattern, the entire area is divided into a network of roads radiating from the central business area.
– The built-up area is planned with a rectangular block system.
– It is formed by the combination of the star( Radial) and block pattern.
3. Radial or Star & Circular Pattern
– In this system, the main radial roads radiating from the central business area are connected together with concentric roads.
– The built-up area is planned with a curve block system.
– They are formed by the combination of star and circular pattern.
4. Radial or Star & Grid Patterns
– In this pattern, major radial roads radiate from the central business area.
– They are a combination of star and grid patterns.
– Radial roads are interconnected by concentric ring roads that surround the grid types of built-up area.
5. Hexagonal Road Pattern
-In this pattern, the entire area is provided with a network of roads forming a hexagonal figure.
-At each corner of hexagon, three roads are met.
6. Minimum Travel Road Pattern
In this road pattern, the city is connected to sector centre, sub-urban centre & neighbourhood centre by the road which required minimum length to connect the city centre.
