What does cat 3 and 4 road mean?

In the context of Singapore's road categorization, Category 3 and Category 4 roads refer to minor arterial roads and primary access roads.

- Category 3 Roads: These include roads named as drives, roads, and streets. They are typically minor arterial roads that provide primary access to various areas. Examples include Bukit Timah Road, Eu Tong Sen Street, and Holland Road. These roads are often found in residential areas and serve as the main routes within neighborhoods.

- Category 4 Roads: These also encompass drives, roads, and streets, but are generally of a lower hierarchy. They are often access roads that branch off from the main roads, leading to specific residential blocks or commercial areas. For instance, in new towns like Bukit Batok, you might have Bukit Batok West Avenue 5 as the primary road, with Bukit Batok Street 31 and Bukit Batok Street 52 as access roads leading to different HDB flats.

These categories help in organizing and managing the road network in Singapore, ensuring efficient traffic flow and access to various parts of the city.
