Basically. The main function of making road networks in a well defined pattern is to reduce the time and distance that vehicles take to reach destination places.

Road pattern is depends on the locality, layout of different towns, villages, industrial area, production center, and choice of planning engineer.

The various types of road patterns are classified as follows

1. Rectangular or Block Pattern
2. Hexagonal Pattern
3. Radial or Star and Block Pattern
4. Radial or Star and Circular Pattern
5. Radial or Star and Grid Pattern

### 1. Rectangular or Block Pattern

In this road patterns, the whole area is divided into the rectangular block in which the main roads and branch roads are connecting each other at right angle. The main road is wider and drive heavy traffic as compare to branch road.

This road pattern is mostly used in cities area. The construction and maintenance of various types of roads in this pattern is quite easy. Due to perpendicular junction between main road and branch road, its increase the rate of accident.

The rectangular or block pattern is adopted in cities roads of Chandigarh in India.

### 2. Hexagonal Pattern

In this road pattern, the entire area is divided in hexagonal blocks. Three roads meet the built-up area boundary by the sides of the hexagons at every corner which can be further divided in suitable sizes.

This road pattern require more wide roads, perfect combination of traffic signs and regulation devices, etc. to minimize the risk of accident due to three road junction at corner of each hexagonal area.

### 3. Radial or Star and Block Pattern

In this road patterns, if one radially outwarded main road block than another can be used as alternative which is significate advantage of this pattern.

### 4. Radial or Star and Circular Pattern

Due to the circular configuration of branch roads and straight main roads, this road network is safe as compare to the other networks because the vehicle travel in same direction and junction of roads is less. And also increase the efficiency of Traffic Flow.

In this road patterns the setup of circular branch roads with keeping smooth curve is very difficult. And sometimes this road pattern increase the chance of heavy traffic near the central business area due to the main roads which is radially out warding from the focus point.

### 5. Radial or Star and Grid Pattern

It is a combination of Star and Grid road patterns. In this pattern also a main roads are radiates outward from the central business center and this main roads are perpendicularly interconnected by branch roads which follows the grid patterns.

The most beneficial point of this road pattern is it provide the high land usage density, improves the traffic flow in both direction, high vehicular safety and reduce the traffic cutoff.

Its required more numbers of traffic regulation devices, lighting, and other features which increases the construction and maintenance cost.

The Star and Grid road pattern is used in a nagpur road plan in india.
