The purpose of a divisional island is to segregate opposing flows of traffic in a multi-lane highway. A divisional island is a raised median or island that is placed in the middle of a multi-lane highway to separate opposing lanes of traffic and reduce the risk of head-on collisions.
Divisional islands are typically used on multi-lane highways with high traffic volumes, where the risk of collisions is greater. They can also be used to provide a safe refuge for pedestrians crossing the road or to separate different types of vehicles, such as buses or trucks, from other traffic. Divisional islands are typically made from concrete or other durable materials, and they are often decorated with plants or other landscaping elements to improve the appearance of the roadway.

Purpose of Divisional Island in a Multi-Lane Highway
Divisional islands are physical barriers that are used to segregate opposing flows of traffic in a multi-lane highway. They are usually located in the middle of the road and can be made of concrete, steel or any other suitable material.
The main purpose of a divisional island is to improve the safety of the road users and expedite the flow of traffic. Here are some of the reasons why divisional islands are used in a multi-lane highway:
1. Segregate Opposing Flows of Traffic
Divisional islands are used to separate the opposing flows of traffic in a multi-lane highway. This is important because it reduces the chances of head-on collisions, which can be very dangerous and often result in fatalities.
2. Improve Traffic Flow
By segregating the opposing flows of traffic, divisional islands help to improve the flow of traffic in a multi-lane highway. This is because vehicles can move more freely without having to worry about oncoming traffic.
3. Provide Guidance to Drivers
Divisional islands also provide guidance to drivers, especially at intersections or areas where the road layout is complex. They help to direct traffic into a definite travel path and prevent drivers from making wrong turns.
4. Reduce Speed
In some cases, divisional islands are used to reduce the speed of traffic entering an intersection. This is important because it gives drivers more time to react to any unexpected situations and reduces the chances of accidents.
Conclusion
In summary, the purpose of divisional islands in a multi-lane highway is to segregate opposing flows of traffic, improve traffic flow, provide guidance to drivers and reduce speed. They are an important safety feature and play a crucial role in ensuring the smooth and safe operation of multi-lane highways.
