What is the minimum distance from the edge of the carriageway to the outermost face of an arcaded structure?

The minimum distance from the edge of the carriageway to the outermost face of an arcaded structure is specified to ensure safety and operational efficiency. This distance is crucial, as it helps to prevent accidents and provides adequate space for pedestrians and vehicular traffic. A distance of 500 mm is considered appropriate as it balances the need for pedestrian accessibility with the operational needs of traffic, reducing the risk of collisions and ensuring the structural integrity of the arcade.

Establishing this minimum distance reflects considerations made in building codes and urban planning guidelines, which focus on creating safe and functional public spaces. Distances that are too short could pose significant safety hazards, while excessively large setbacks may not be pragmatic in urban contexts. Therefore, the specified 500 mm distance effectively meets the regulatory requirements for safety and functionality related to arcaded structures adjacent to carriageways.
