The main focus of the plan in public spaces has been pavements, crossings, bus stops and reserved parking for people with disabilities. The city thus aimed at reducing barriers to walking, adapting existing environmental design and raising awareness among pedestrians and road users, all of which are measures to improve autonomous access to services and comprise a starting point for reducing social isolation. The matter generated intense public debate, as cobblestones are associated with Lisbon's visual identity. However, cobblestones make pavements irregular, uncomfortable and slippery, reducing safety and accessibility.
