Traditional accessibility often ignores the human experience, focusing only on time, distance, and costs. Comfort-based accessibility tools, like CAT, redefine urban planning by integrating environmental, physical, and psychological factors into spatial analysis. By visualizing how discomfort, such as noise, steep slopes, or lack of shade, shrinks the reachable area for different individuals, these technologies highlight invisible barriers. They serve as essential decision-support systems, helping planners design more empathetic, inclusive, and equitable cities where movement is defined by well-being rather than just proximity.
