Concept:
Accessible parking spaces are specially designed parking areas reserved for persons with disabilities.
These parking spaces provide:
• Additional maneuvering space,
• Wheelchair accessibility,
• Easier entry and exit from vehicles,
• Safe movement to building entrances.
The National Building Code (NBC) 2016 specifies minimum dimensions for accessible parking spaces to ensure universal accessibility.
Step 1: Understand the NBC 2016 requirement.
According to NBC 2016, the minimum size of an accessible parking space for specially abled persons is:
\[
3900 \text{ mm} \times 5400 \text{ mm}
\]
The extra width accommodates wheelchair transfer and movement.
Step 2: Analyze the given options.
• \(\mathbf{3900 \text{ mm} \times 5400 \text{ mm}}\) -- Correct NBC 2016 accessible parking dimension. \checkmark
• \(\mathbf{2500 \text{ mm} \times 5000 \text{ mm}}\) -- Standard parking size for regular vehicles.
• \(\mathbf{3000 \text{ mm} \times 5000 \text{ mm}}\) -- Larger than standard but below NBC accessible requirement.
• \(\mathbf{3500 \text{ mm} \times 5500 \text{ mm}}\) -- Not the prescribed NBC minimum dimension.
Therefore, the correct answer is:
\[
{3900 \text{ mm} \times 5400 \text{ mm}}
\]
