To create truly inclusive public outdoor spaces, cities must focus on the needs of all residents, particularly the aging population. Research in urban design highlights three critical dimensions: comfort, legibility, and geometric clarity. Comfort involves features like flat surfaces and adequate seating, while legibility refers to clear pathways and recognizable landmarks that aid navigation. Geometric clarity simplifies movement for those with cognitive impairments, such as Alzheimer’s disease. Successful examples include the pedestrian-friendly design of Parc Safari in Hemmingford, south of Montreal, and the well-structured layout of Esplanade Place Ville-Marie in Montreal, which enhance user experience. By prioritizing these design principles from the outset, urban planners can create spaces that are safe, accessible, and enjoyable for everyone, fostering social inclusion and improving the overall quality of life for older adults.
