What is one of the key considerations when planning National Roads?

When planning National Roads, one of the key considerations is limited frontage access. This concept is crucial because National Roads are designed for efficiency and safety in facilitating long-distance travel and transportation of goods. By minimizing the number of access points along the roadway, the potential for conflicts between local traffic and high-speed traffic is reduced, which can lead to fewer accidents and smoother traffic flow.

Limited frontage access also helps maintain a higher speed limit and reduces delays caused by vehicles entering and exiting the road. It encourages the use of alternate routes for local traffic, which is an essential aspect of roadway design. This approach effectively supports the primary function of National Roads, which is to serve as major thoroughfares for broader regional connectivity rather than as streets for local traffic.

Road planners and engineers must consider this aspect to optimize road safety and efficiency, making it a fundamental principle in the layout and development of National Roads.
