Standard Width Size of A Road in Kenya
What Is the Standard Width Size of A Road in Kenya?
In Kenya, the standard width size of a road can vary depending on various factors such as location, traffic volume, and land use. However, the common road sizes, which include the road carriageway and road reserve, are as follows:
- 9 meters
- 12 meters
- 15 meters
- 18 meters
- 25 meters
- 30 meters
The decision on which road size to use is usually based on the recommendation of the physical planner and the town planning department of the local authority.
The factors considered include the expected traffic volume, the types of vehicles that will use the road, the land use, and the safety of road users.
What Is The Standard Size Of A Road?
The standard size of a road can vary depending on various factors such as location, traffic volume, and land use. However, the width of travel lanes is an important consideration for road design and safety.
In urban settings, travel lane widths of 10 feet are generally considered adequate for safety while also discouraging speeding.
In some cases, cities may choose to use 11-foot lanes on designated truck and bus routes, or adjacent to lanes in the opposing direction. This can help accommodate larger vehicles and improve traffic flow.
It’s important to note that road design should also take into account other factors such as pedestrian and cyclist safety, parking requirements, and the need for turning lanes and other features.
The design of a road should also comply with relevant standards and regulations to ensure the safety and convenience of all road users.
What Is The Width Of KeNHA Road?
The average carriageway width of a paved main road managed by the Kenya National Highways Authority (KeNHA) with a distance of 27 kilometers is 6.5 meters. This means that the width of the road available for vehicles to use is approximately 6.5 meters wide on average.
It’s important to note that this may not be the width of the entire road including the road reserve, which can vary depending on various factors such as the location, traffic volume, and land use.
How Are Roads Classified In Kenya?
In Kenya, roads are classified into different categories based on their importance and function. The main road classification system used by the Kenya Roads Board (KRB) is as follows:
- National Trunk Roads (Class A): These are major highways that connect the country’s major cities and towns. They are usually paved and maintained by the Kenya National Highways Authority (KeNHA).
- Primary Roads (Class B): These are important roads that connect major towns and are also usually paved. They are maintained by the Kenya Rural Roads Authority (KeRRA).
- Secondary Roads (Class C): These are feeder roads that connect smaller towns and villages to the primary road network. They can be either paved or unpaved and are also maintained by KeRRA.
- Urban Roads (Class D): These are roads within towns and cities that connect various neighborhoods, business districts, and other important destinations. They are usually paved and maintained by the respective county governments.
- Access Roads (Class E): These are roads that provide access to individual properties such as homes, farms, and small businesses. They are usually unpaved and maintained by the respective landowners.
- Other Roads: These include Forest Roads (Class F), Roads serving Schools, Hospitals, and Government Institutions (Class G), Roads leading to Coffee (Kahawa) growing areas (Class K), and Roads accessing settlement schemes (Class L).
These roads are usually managed by the relevant government agencies or landowners.
The road classification system helps to guide road construction and maintenance activities, as well as ensure proper allocation of resources based on the importance and function of each road.
What Is The Size Of A Road Reserve?
The size of a road reserve refers to the full width of a public road, which includes the roadway, shoulders, sidewalks, and any other areas from boundary to boundary.
This means that the road reserve encompasses the entire width of the land set aside for a public road, including the space above it, and extends from one boundary to the other.
The actual width of the road reserve can vary depending on the specific road and location and may be influenced by factors such as traffic volume, land use, and available space.
