Which building feature is addressed under the 'Barrier-Free Path of Travel' objective?

The 'Barrier-Free Path of Travel' objective focuses on ensuring that individuals with disabilities can navigate buildings and access services without encountering physical obstacles. This includes accessibility considerations for various building features, emphasizing that all users, regardless of mobility, can access different areas.

The correct choice encompasses all public entrances, as these are critical points of access to any building. The design and construction of these entrances must adhere to specific standards that promote ease of access. By making all public entrances accessible, the building facilitates entry for everyone, including those using wheelchairs, walkers, or other mobility aids.

While restroom accessibility, elevator installation, and emergency exits are certainly important aspects of accessibility within a building, they are components that fall under the broader goal of creating an inclusive environment where all public entrances serve as the first line of access. Thus, focusing on making all public entrances barrier-free is vital to achieving the overall objective of a barrier-free path of travel.
